GLYPTOBASIS SPINICORNIS. 



The following part is almost angularly curved inwards and 

 bears two large, equal, sharp spines at the innerside; the 

 rest, which is nearly straight, bears three feebler spines 

 at its base, which increase very distinctly in size towards 

 the tip. 



Head black, with dense black villosity on the face and 

 between the antennae. Vertex and occiput yellow. Eyes 

 bronzy. 



Thorax and legs black with black villosity, the yellow 

 stripe on the dorsum is as in G. nugax Wlk., the oblique 

 stripe on the breast is cream to yellowish. 



Abdomen in both sexes shorter than the hindwings, 

 yellowish above, venter and sides black. The gonopoda of 

 the <ƒ (fig. 2) have short and somewhat curved app. sup., 



^. . the tips of which are thick

and broad with many short 

 spines. The genitalvalve is 

 more primitively formed than 

 in the other species of this 

 genus and broadly pentago- 

 nal. 



The wings are more nar- 

 rowly petiolated and broader 

 than in dentifera and nugax. 

 The pterostigma is pale brown 

 to black, with 5 crossveins. 

 The apicalfield has 3 — 4 rows 

 of cells. 

 Nervature brown and dense. 

 In both wings are 8 — 11 

 cells between the ramus obli- 

 quus and the postcosta, in the hindwings this number is larger 

 than in the fore wings. Radialsector with 7 — 8 branches. 

 Between cubitus inferior and hindborder are at the most 

 14 cells in one row in the forewing, in the hindwing 9 

 cells. Membrane hyaline in the <ƒ, in the 9 the tips of 

 all wings have a brown quadrangular spot, which is of
