about equal length. The third antennal segment and its appen- 

 dage do not, in this species, appear as such : in fact if one considered 

 this species alone the reason for considering the appendage present 

 at all would not be apparent, but if one would imagine the appen- 

 dage of the third segment in a form such as G. processus (described 

 elsewhere in this paper), which is visibly appendage-like, as enlarged 

 so as to become continuous with the segment proper, and imagine 

 the last two joints as much reduced, he would see just such a form 

 as we are now desctibing, and see the origin of this type. Below 

 the antenna is a rounded ocular blotch and the clear prominent 

 eye which bears posteriorly a short hair The temples are quite 

 square and are rather darker coloured than the rest of the head, and 

 the margin, which is bordered by a pale, broken band ending in a 

 narrow blotch behind the eye, bears two long, stout hairs and 

 three short spines. Occiput concave, slightly sinuous, bare. 



Thorax much longer than head. Prothorax trapezoidal with 

 sides divergent and bordered by a dark band ; posterior angles 

 acute, bearing a long hair ; posterior margin indefinite. Metatho- 

 rax slightly broader than head, triangular, with apex forming a 

 slightly obtuse angle on the abdomen ; anterior lateral margins 

 curved, with marginal bands which curve in toward the meson ; 

 the coxal bands appear within, parallel to those just mentioned. 

 Each of the rounded lateral angles bears two hairs on a pustule, 

 while on the posterior margin on each side are three submarginal 

 hairs, two together near the lateral angles and one near the meson. 

 Legs pale, ordinary. 



The abdomen is shorter than the head and thorax together, 

 is short and rounded, widest at the third segment ; on each seg- 

 ment are lateral marginal bands, well chitinized, those behind 

 the first entering into the segment preceding and curving in- 

 ward. The large, dark, transverse blotches do not meet in the 

 centre, the space left being uncoloured ; dorsal hairs occur 

 on the first five segments, confined to the central area, and 

 on these segments, near the inner termination of the late- 

 ral marginal bands below the spiracles, arises a group of 

 three or four hairs. The last three segments are compressed, 

 the last entire and not reaching back as far as the one before, 

 nor that one as far as the one before it ; there is a fringe of 

 about twen£y-two long hairs across the dorsal surface of the last 

 segment and the usual ones in the lateral angles of the other 

 segments. The genitalia are prominent with heavily chitinized 

 rods reaching to the second abdominal segment.
