 (Plate VIII.) 



Corydalis asiatica, n. sp. 



c$ 2 • Head and thorax above brown (? green in the living 

 insects), symmetrically marked with black or dark brown. Antennae 

 simple and setaceous. Head with a pair of minute spinules on its 

 disk just internal to the lateral pair of ocelli. Mandibles coal-black, 

 with a shallow rounded emargination at the base on the inner side. 

 Anterior tibiae rather strongly g-curved. Abdomen brown, without 

 brown or black marks. Wings all subhyaline, faintly washed with 

 smoky, darker smoky at the anterior margin ; the anterior pair devoid 

 of pearly white specks, but presenting, especially near the principal 

 vein, a few indistinct elongated discal blotches resembling dried 

 splashes of muddy water. 



d • Much larger than the female. Mandibles greatly elongated, 

 curved, crossed, and depressed, about twice as long as the head, 

 having a minute rudimentary tooth near the apex on the inner side ; 

 the margination at their base on the inner side conspicuous. Anal 

 appendages short and stout. Labrum invisible from above between 

 the bases of the mandibles. Antennae (broken)? rather longer than 

 in the female. 



$ . Mandibles only about as long as the head, 3-toothed on the 

 inner side of their distal half. Labrum visible from above between 

 the bases of the separated mandibles. 



Hab. Naga Hills, N.E. frontier of India. The first specimen, 

 a female, was obtained by Lt.-Col. H. H. Godwin-Austen ; subse- 

 quently a male and a female were obtained by Messrs. Ogle and 

 Chennell. 



All the previously described species of this genus are American.
