border and a black stripe which is dilated on the fore border, and in the 

 middle a luteous dot on each side and a posterior luteous streak, the latter 

 ending in a dot ; sides straight. Oviduct tawny, slightly curved upward, 

 much longer than the abdomen. Legs stout, rather long; femora indis- 

 tinctly streaked with piceous ; hind femora with three minute black-tipped 

 spines on the outer side and with two on the inner side, the first of the 

 latter extremely minute ; fore tibiae black above ; four posterior tibiae with 

 a black band near the base; hind tibia? with four minute black-tipped spines 

 on the outer and with five on the inner side. Wings pale cinereous, full 

 as long as the body ; veins pale. Length of the body 16 lines ; of the 

 wings 36 lines. 



The markings of the head and of the prothorax will distinguish it from 

 G. libialis, to which it seems to have most resemblance.

33. GHYLLACBIS ALIENA. 



Fo3m. Testacea ; caput prothorace latins, antice rugulosum, vertice sub- 

 globoso, fascia frontati lata niyra ; prothoracis laterafere recta; ovi- 

 ductus brevis, valde recurvus ; pedes longiusculi, pubescentes, tibiis 

 basi piceo unifasciatis ; alee abdominis dimidio paullo longiores. 



Female. Testaceous, smooth, shining. Head rather broader than the 

 prothorax, somewhat tumid on the fore part of the vertex ; a broad black 

 band on the front, which is transversely and finely rugulose; face largely 

 rugulose. Eyes piceous, prominent. Mandibles black. Fifth joint of the 

 maxillary palpi longer than the fourth, hardly incrassated at the tip ; third 

 joint of the labial palpi clavate, truncated. Prothorax slightly transverse, 

 with a transverse furrow near the fore border and with an oblique furrow 

 on each side; border slightly reflexed, sides nearly straight. Oviduct 

 about one-third of the length of the abdomen, over which it is recurved. 

 Legs stout, pubescent, rather long ; hind femora with six minute black 

 spines on each side, four on the inner side extremely minute; tibia? with a 

 piceous band near the base; hind tibiae with six minute black-tipped 

 spines on each side. Wings rudimentary, a little more than half the 

 length of the abdomen ; fore wings shorter than the hind wings. Length 

 of the body 14 lines. 



The specimen described is probably immature. The much-retracted 

 oviduct distinguishes it from the other species here described.
