The whole of the abdomen is rufous ; and the posterior fascia is recurved more on the margin and less on the suture. The distinction of the alutaceous surface of the thorax appears to m e also to be a good character. Two specimens in Murray's collection, purchased by me, are labelled n. sp. in Crotch's handwriting. 19. AULACOCHILUS INCLYTUS. Niger, supra carulescens, nitidus, capite thoraceque fere glabris; elytris valde convexis, singulis maculis duabus magnis subrotun-datis fulvis, striis obsoletissime punctatis, fere obliteratis. Long. 10g-ll millim. Hab. Philippine Islands, Panaon (Semper). This species is distinguished from all its congeners (except A. doria) by having /our large subquadrate or roundish red spots, of which the hinder one is not arcuate, on its elytra. Of these this one is separable by the blue shining thorax, which is scarcely visibly punctate ; the head has a few scattered punctures, which are distinct under a good glass. The elytra are somewhat cordate; the front spot touches the base and just reaches the scutellum, it leaves the humeral callus and margin black ; the hind spot is squarish, sometimes transverse, very nearly reaching the suture and margin. The underside is almost or quite black, without any of the blue tint observable in the whole upper surface. This species is not in the Crotch collection at Cambridge. 20. AULACOCHILUS AGABOIDES. (Plate XVIII. fig. 10.) Ovatus, niger, nitidus; capite distincte, thorace minute haud profunde punctatis; elytris tenuiterpunctato-striatis, singulis maculis duabus, una basilari intus tridentata, altera ante apicem valde arcuata ; abdomine rufo, segmento basali nigro. Long. 8 millim. Hab. Philippine Islands, E. Mindanao, N. Luzon (Semper, Cuming). The ground-colour of this species is quite black; the basal spot occupies the whole base, extending in an oblique direction from the scutellum across the shoulder, but leaving the reflexed edge of the margin black ; it emits three rather long denticulations, between the first and second of which it is excavated rather deeply; the hind spot is undulated on its basal, produced on* each side of its apical margin ; both the spots are usually pale yellow. The elytra are finely punctate-striate, the interstices very finely, scarcely visibly punctate ; the abdomen pitchy-red excepting its basal segment, or very nearly quite black. I have seen one specimen of this in the Crotch collection at Cambridge. The specimens taken by Cuming were obtained by m e from Mr. Waterhouse's collection. |
