The palpi have the humeral joint moderately long and slender: the cubital joint is clavate, slightly bent downwards, and about half the length of the humeral joint: the radial joint is short, spreading, prominent behind, and produced at its fore extremity on the upper-side into a very large apophysis, covering the greater portion of the digital joint; this apophysis is considerably the broadest at its fore extremity, where it is strongly emarginate or bifid, the outer limb of the bifid part being the longest, prominent, and obtuse, and broadest at its extremity ; the inner one has a curved point directed rather downwards, and just within this curved point is a small, slightly-curved, sharp-pointed spine: the digital joint is of moderate size and of a somewhat oblong form : the palpal organs are well developed and complex; from their fore extremity a strong, black, tapering,- sharp-pointed spine curves round outwards and backwards in a somewhat sinuously circular form. The falces are neither very long nor strong ; they are obliquely cut away on their inner sides towards the extremities, armed with minute teeth, and directed strongly backwards towards the maxillae. The maxilla, labium, and sternum are normal in form and structnre. The abdomen is large, of an oval form, tolerably convex above, and projects over the base of the cephalothorax ; it is of a dull brownish black colour, and sparingly clothed with short hairs. A single example of the adult male of this species was sent me by M . Eugene Simon from the Col de Natoia in France ; it is very similar to some others in the form of the cephalothorax ; but the structure of the palpi will serve to distinguish it at once. ERIGONE COCCINEA, sp. n. (Plate XXVIII. fig. 14.) Adult male, length nearly li line. The cephalothorax, falces, maxillae, labium, and sternum, as well as the upper part of the abdomen, of this Spider are of a bright orange-red colour, that of the legs and palpi being bright orange-yellow. The cephalothorax has the hinder, or thoracic, portion marked with strong circular punctures, disposed in converging lines, following mainly the course of the normal indentations : the caput has an oval, tolerably strong eminence near the occiput; the fore extremity of the caput is also prominent, thus dividing the caput into two tolerably distinct lobes, of which the foremost or lower one is the strongest; the upper lobe is divided laterally from the lower one by a large excavation running backwards from its broadest and deepest part, above and behind each lateral pair of eyes, to the hinder part of the upper lobe (or eminence) ; the front slope of this eminence is steep though rounded ; but the hinder one is much more gradual: the height of the clypeus is about half that of the facial space, its upper part is rounded and prominent, the lower part impressed and retreating ; on the fore slope of the cephalic eminence are a few bristly black hairs directed forwards and downwards, meeting a few |
