POCOCK ON THE S C O R P I O N S [Mar. 18, spots : the fourth caudal segment of L. fischeri is described as infuscate; in L. nigrimanus it closely resembles the second and third segments in presenting an inferior median fuscous band and two antero-lateral fuscous spots: the bandm L. fischeri is furnished with blackish lines ; in L. nigrimanus it is wholly fuscous: in L. fischeri the general tint is " flavo-fuscus " ; in L. nigrimanus it is olivaceous: and lastly the seventh tergite in L. fischeri is furnished with only a median keel, whereas in L. nigrimanus the two lateral keels in each side are distinct although not well developed. It must be borne in mind, however, that specimens of the typical L. fischeri have been recorded by Dr. Karsch from Madagascar as well as from Barawa. Consequently on account of the wide range of this species it is quite likely that fresh collections will show that the characters here relied upon are too unstable to be even of varietal importance. In the Ann. Soc. Ent. Fr. (5) x. p. 397, M . Simon expresses an opinion that his species, Lepreus occidentalism (Plate XIV. fig. 4 ) , may he synonymous with L. fischeri, Karsch. But judging from tbe series of occidentalis that the Museum possesses-namely two from the Gaboon, six from Angola, and two from the Congo-the two species are distinct, although very closely allied; occidentalis may be at once recognized by the presence on the under surface of the tail of three fuscous bands, whereof the lateral are bifid in front; in fischeri there is a single median band and two anterior spots. UROPLECTES INSIGNIS, sp. n. (Plate XIII. fig 4.) Colour variegated, testaceous and fuscous, the latter predominating ; the tubercle and ante-ocular area infuscate, the posterior and lateral portions of the cephalothorax variegated; tergites with a testaceous stripe close to each side margin, a V-shaped testaceous mark nearer the centre, and a large yellow median patch which behind is divided by a black streak covering the median keel; upper surface of caudal segments infuscate in the middle, testaceous at the sides, lateral and inferior surface of the anterior segments adorned with black lines ; inferior surface of the fifth almost wholly black ; vesicle banded with yellow. Humerus and brachium infuscate above, manus lined and reticulated with black : dactyli infuscate at the base; femora with a black line along the lower margin, patellce testaceous in the middle, tibice and tarsi with a patch of black at their proximal ends; under surface almost wholly testaceous, the last tergite with a conspicuous black band on each side. Cephalothorax somewhat coarsely, but sparsely, granular; the ocular tubercle wholly smooth. Tergites nearly smooth in front, coarsely and sparsely granular posteriorly ; the first six furnished with an abbreviated smooth keel; the last with two coarsely granular keels on each side and a median nearly smooth prominence in its anterior half. Sternites wholly smooth throughout, very sparsely hairy. 1 ? Syn. Tityus chinchoxensis, Karsch, Zeitschr. ges. Naturw. 1879, |
