172 NEMATUS PAVIDUS. 



and covered sparsely with greyish pile ; the prone-turn and meso- 

 sternum luteous. Abdomen a little longer than the head and thorax, 

 projecting in the middle, broadly rounded at the apex ; the extreme 

 base, a spot on the outside of the blotch (which is very large), black ; 

 the saw black at apex, hairy ; the cerci are short. Legs yellow, pale 

 white at the coxa3 and trochanters, the posterior tarsi a little fuscous 

 and shorter than the tibiae, spurs a little shorter than the half 

 of the metatarsus ; the claws bifid. Wings hyaline, the nervures 

 deep black, costa and stigma sordid luteous ; the first transverse cubital 

 nervure is a little faint ; the second cubital cellule is double the length 

 of the third, which is a very little dilated at the apex; the second 

 recurrent nervure is received about half the length of the third cellule 

 in front of the second transverse cubital nervure. 



The c? is coloured like the ? , except that there is a row of black 

 bands down the back of the abdomen and the antenna are closely 

 pubescent, compressed, and fuscous beneath. The extent of the black 

 on abdomen varies, and may be absent except at base. 



Length 3? lines. 



Ab. a. Antennge fuscous on the underside. 



Pavidus is very similar to N. albipennis, but differs 

 in the hyaline wings, more sordid costa and stigma, in 

 the second recurrent nervure not being interstitial, the 

 eyes more broadly bordered with luteous, the scutellum 

 smooth and not punctured, &c. 



Larva. Head much smaller than the second segment, 

 deep black, the mandibles brown. Legs yellowish- 

 white ; spot at the base of the tarsi and the claws black ; 

 ventral legs glassy green. Body green, except the 

 second and the last segment, which are orange-yellow. 

 A black line goes down the centre of the back. On 

 each side there are two black lines somewhat broader 

 than the dorsal; below these again is another line 

 of dots arranged thus : first, a large roundish dot, 

 then two smaller, and then a larger ; directly over the 

 legs are two dots, one longish, the other roundish, 

 placed one over the other. There are no marks on 

 the orange-coloured segments. 



When young the lines down the back are seen to be 

 composed of dots separated from one another, instead 

 of being continuous. The anal segment also wants 

 the yellow colour, except at the extreme apex, which 

 has a small black spot over it. 



The eggs are laid in a cluster on the underside of
