2. Cryptosalius pandiyanus, sp. n. 



?. Nigra, albopilosa; mandibulis ferrugineis, apice nigris; an- 

 tennis tarsisque anticis fuscis; alis flavohyalinis, apice late infu- 

 matis, venis testaceis; vertice, pronoto postice, segmento mediano 

 postice, segmentis dorsalibus 1^ fascia lata apicali, segmentoque 

 sexto, dense albopubescentibus ; pronoto elongato, mesonoto duplo 

 longiore. 



Long. 6-8 mm. 



$. Head longer than the greatest breadth; clypeus short, the 

 apical margin widely and very shallowly emarginate. Posterior 

 ocelli about half as far again from the eyes as from each other; 

 inner margins of the eyes parallel; the front with a distinct but 

 very shallow longitudinal sulcus extending to the anterior ocellus. 

 Front, pronotum and median segment, except broadly posteriorly, 

 clothed with very short and sparse fulvous pubescence. Antennae 

 short and stout, not more than twice as long as the head, second 

 and third joints of the flagellum subequal. Pronotum at least 

 twice as long as the mesonotum, narrower than the head, as long 

 as the greatest breadth, very slightly narrowed anteriorly. Meso- 

 notum very short; median segment shorter than the pronotum, 

 obliquely sloped posteriorly, the sides parallel. Second ventral 

 segment with a distinct transverse groove near the base. The 

 whole ventral surface clothed with very delicate silver pubescence. 

 Anterior tibiae produced at the apex without and ending in two 

 spines; hind tibiae smooth. Second abscissa of the radius longer 

 than the third ; first recurrent nervure received close to the middle 

 of the second cubital cell, second at about three-quarters from the 

 base of the third cubital cell; submedian cell much longer than 

 the median, cubitus of the hindwing interstitial with the transverse 

 median nervure.

This is a much smaller species than C. rava, and may 

 be distinguished by the very much longer pronotum, 

 which in rava is much broader than long and no longer 

 than the mesonotum. The third cubital cell is shorter 

 than in rava and receives the recurrent nervure nearer to 

 the apex. There is some difference in the present species 

 in the length of the third cubital cell, specimens taken in 

 July and August having the third abscissa of the radius 

 as long as or longer than the second. The type was taken 

 in January. There is also some variation in the position
