CLEMENS. 



DARAPSA WALKER. 



Size moderate, body rather slender and tapering. The head is 

 small, narrow, and almost sessile ; the vertex subtufted, front ver- 

 tical ; the eyes small ; the palpi short and rather slender ; the 

 tongue about one-half as long as the body ; the antennae a little 

 longer than the thorax, slender and almost filiform, with a long 

 hook without seta. The thorax is rather short, almost globosely 

 rounded in front. The abdomen oblanceolate, thrice as long as 

 the thorax. The anterior wings are as long, or somewhat longer 

 than the body, twice and a half longer than broad across the inte- 

 rior angle ; the tips acuminated, the hind margin excavated rather 

 deeply from beneath the tip to medio-superior vein, and thence 

 convex to the interior angle ; the inner margin deeply concave 

 above interior angl-e. Posterior wings with tips rather pointed 

 and hind margin somewhat excavated before the interior angle. 

 Male. Antenna prismatic and ciliferous. Female. Antennas slen- 

 der and almost filiform. 



Larva. Head very small and elongate-globose. The body 

 tapers suddenly to the head, from the anterior portion of the third 

 segment, which, together with the fourth and fifth, are much swollen. 

 The anterior rings are retractile within the fourth. A caudal horn 

 on the eleventh segment. It is ornamented with a subdorsal line 

 and irregularly oval lateral patches. The larval transformation 

 takes place on the surface of the ground in an imperfect cocoon, 

 consisting of vegetable debris united by silken threads.
