SCOLOBATES.— -BANCHUS. 311 



tures, and covered with longish fulvous hair ; the antennae originating from tubercles ; 

 the clypeus depressed round the base; eyes oblong, comparatively small; the space 

 behind the eyes considerably developed. Thorax shining, impunctate ; mesonotal 

 sutures obsolete ; scutelluni moderately raised, longer than broad, the sides not keeled ; 

 metathorax depressed at the extreme base, and having a gradual slope to the apex ; the 

 spiracles round, and situated a little before the middle. Abdomen a little longer than 

 the head and thorax united, shining, impunctate, covered with a dense fuscous pile ; 

 becoming gradually widened to the apex of the fourth segment, thence gradually 

 narrowed; the apices of the second and following segments and the ventral surface 

 testaceous. Legs stout, the tarsi densely pilose ; hind tibiae curved inwardly, the spurs 

 short and thick; metatarsus narrowed and bent at the extreme base, scarcely so long 

 as the three following joints united ; the second tarsal joint longer than the third, the 

 latter twice the length of the fourth, the fifth joint (with the claws) a little longer 

 than the second. There is no areolet ; the recurrent nervure is interstitial. 



In this insect the neuration of the wings is as in Heteropelma sonorensis and Beta- 

 nisia ; the much thicker hind tibia? and tarsi (the tarsi, moreover, being longer than 

 the tibiae), the non-lobed mesonotum, and the smaller eyes (which do not reach so near 

 to the clypeus) sufficiently distinguish it from the latter. The short antennae, the large 

 eyes (reaching quite near to the mouth), the long compressed abdomen, the broader 

 scutellum, and the more slender tarsi (of which the metatarsus is also longer), separate 

 Heteropelma from 8. varicornis.

Antennae not much longer than the head and thorax united, involute, stout, micro- 

 scopically pilose. Head much broader than long, not much developed behind the eyes ; 

 the latter curve round on the top, and reach nearly to the base of the mandibles ; an 

 oval depression over each antenna; the face slightly projecting in the middle; the 

 clypeus transverse at the apex, the sides oblique ; the mandibles without teeth ; the 

 face and clypeus punctured ; yellow, the depressions over the antennae and the space 

 between them black; the centre of the face and the base fulvous; the tips of the 

 mandibles black, the palpi yellow. Thorax rather strongly and closely punctured, fulvous; 

 the scutellum not so strongly punctured and ending in a sharp nipple-like point; 

 scutellum (except the point and a line down from it), a spot in front of the mesonotum, 

 a quadrate mark beneath the tegulae, a broad mark on the mesopleurge in front, and
