covered with silvery pile ; wings flavo-liy aline, nervures and 

 tegulse light testaceous. 



^ . Similar, the clypeus and front with golden pile, the 

 pile on the mesonotum appearing also golden in some lights ; 

 all the tarsi are more or less rufous, and in some specimens 

 the whole of the second and the basal half of the third 

 abdominal segments are red. 



Long. 7-10 millim. 



Hah. Deesa, Mt. Abu ; not common. 



Next to T. auriceps^ but differs from that species in the 

 sculpturing of the median segment, and in the greater part 



Trypoxylon responsum, sp. n. 



$ . Head very minutely punctured ; thorax and abdomen 

 smooth ; clypeus rounded anteriorly, its margin slightly 

 curved upwards ; a carina above the base of antennfe, joining 

 on to a furrow from the anterior ocellus ; posterior margin 

 of pronotum slightly constricted ; median segment with a 

 median longitudinal furrow and two lateral convergent 

 furrows, all obscurely transversely striate, the lateral furrows 

 sometimes ill-defined ; abdomen about twice as long as head 

 and thorax united. Black : the apex of the mandibles and 

 the second and third abdominal segments more or less red ; 

 the base of the tibiae and the whole of the anterior and inter- 

 mediate tarsi pale testaceous ; clypeus and front from below 

 the emargination of the eyes, side of pronotum and thorax, 

 and sides and apex of median segment with silvery pubescence. 



Long. 13 millim. 



IJab. Mount Abu ; three specimens. 



Nearest to T. canaliculatum, from which it differs in size 

 and in the clypeus not being carinate. 



AmmopJiUa Smithii (Baly). 



The description of this species, which Bingham had not 

 seen, and which is therefore only quoted by him, leaves 

 much to be desired ; and as I have taken both sexes of an 

 Ammophila^ which I have little doubt is this species, I take 

 this opportunity of giving a detailed description : — 



? . Head and pronotum almost smooth ; mesonotum and 

 scutellum sparsely punctured ; median segment finely trans- 

 versely striate in the middle above, the striation difficult 

 to distinguish ; abdomen smooth, pruinose ; clypeus very 

 convex, transverse anteriorly, a median furrow from base of 

 antennae to anterior ocellus, where it bifurcates in the direction
