88 SPOLIA ZEYLANTCA. 



pronotum, represents the scutellum. It is broadly triangular in 

 form, except that the apex is rounded, and has a smooth surface 

 sparsely covered with minute recumbent hairs. Similar hairs 

 occur on the dorsal surface of the thorax proper, the integument of 

 which is sculptured in the same manner as that of the head. In 

 lateral view the thorax is distinctly divided into three segments ; 

 the metathorax extends backwards for some distance on the sides 

 of the abdomen, forming an acute triangle with the two long sides 

 somewhat curved ; the bases of the posterior legs are situated at 

 about one-third of the length of the whole insect, if the measurement 

 is taken from in front backwards. 



Wings. — The wings, although very narrow, are distinctly spindle- 

 shaped and acutely pointed. They lie parallel to the sides of the 

 body with the tips pointing obliquely downwards and reaching a 

 point some little distance behind the level of the third coxse. No 

 veins are apparent, but there are three distinct rows of minute 

 bristles running along the surface. The hal teres are almost 

 cyhndrical ; they are situated on the lateral surface of the meta- 

 thorax. 



Legs. — The legs are short and stout. In all the femora are dilated , 

 but only compressed to a moderate extent ; they are longer as well 

 as much broader than the tibiae, the latter being cylindrical and 

 much shorter than the tarsi, the first joint of which is the longest ; 

 the tarsi are longer than either the tibiae or the femora. The coxse 

 of the first pair of legs are almost as long as the femora, which they 

 resemble in form ; those of the intermediate and posterior legs are 

 short, but they are rendered conspicuous in the case of the inter- 

 mediate pair by bearing a bunch of stout but almost recumbent 

 black bristles on the anterior face. Similar, but much shorter, 

 bristles also occur on the posterior coxse. The whole of the surface 

 of the limbs is clothed with short recumbent hairs, and the inter- 

 mediate and posterior tibise bear several short bristles disposed in 

 a semicircle at the tip ; the posterior tibiae also bear in the same 

 position a single stout bristle or spur. There are two slender, 

 strongly curved, smooth-edged claws on each foot ; the pul villus 

 consists of a slender longitudinal process bearing a number of 

 elongate downwardly -directed branch-like projections, and the 

 empodium is bristle-like. 



Abdomen. — The abdomen is considerably swollen, but tapers 

 towards the tip and is much longer than broad or deep ; its segmen- 

 tation is obscure. The whole of the integument (with the exception 

 of the scutellum) is soft, almost colourless and naked. The external 

 genitalia form a short projecting tube, the dorsal surface of which is 

 divided into two short lobes bearing long curved bristles ; similar 

 bristles also project from the ventral part of the tube. 



Habitat. — Peradeniya, Kandy District, Ceylon ; altitude about 

 1,500 ft.
