c?. Antennal joints 4-11 mid the abdomen nigro-piceous or black; basal 

 joint of anterior tarsi dilated; anterior and intermediate femora incrassate; 

 anterior tibiae tbiclvened towards the apex, tlie intermediate pair stout, curved^ 

 strongly sinuate within ; protliorax as wide as the elytra, the latter appearing 

 relatively narrower. 



Length 2|-3| mm. (J $.) 



Hah. Sundevdhunga and Pindar A^alley, alt. 8000-12,000 ft. 

 (//. G. C. : vi.l919, and vii.1920). 



Three males and live females, found on Howlers of Crataepis. Smaller 

 than the Ein-opean A. canaliciihdum Er., which is also a mountain 

 insect ; tlie head testaceotis ; the prothorax more rounded at the sides, the 

 puncturing of the upper surface much liner, the emargination of the 

 intermediate tihiie not })reeeded by an angular dilatation. I have beaten 

 A. liirlelhnn Heer in great abundance from the flowers of JPz/rus aria 

 in the French Alps. The elongate basal joint of the posterior tarsi 

 separates A. piiidat'ense from similarly-coloured Aittliohii. 



EuDELipiiEi'M, n. gen. 



Mandibles .short, acutely pointed, unarmed within ; ligula feebly emargi- 

 nate ; maxillary pal])i long, slender, joint 4twice the length of 3 ; antennae long ; 

 lif^ad short, excavate, the ocelli prominent; prothorax explanate laterally; 

 eh'tra carinate laterally, the inflexed portion broad, attenuate postei'iorly ; meso- 

 sternum not einarginate in front, shar]ily, triangularly produced between the 

 intermediate coxae ; tibiae setulose : joints 1 and '2 of posterior tarsi subeqt al, 

 a little longer than 3 or 4 ; tarsal claws simple. 



The above-mentioned characters are sufficient to distinguish this 

 remarkable river-bank Himalayan Omaliid from its allies. In the 

 slender maxillary palpi, with the apical joint twice the length of the 

 third, it approaches DeUplirum and PIn/llodrepoidcs ; the antennae are 

 long, w'ith elongate third joint as in Lcsiera and Geodromiais ; the 

 anterior tibiae of the S are angularly dilated at about the middle 

 beneath, as in the same sex of the European Aiyedium qiiadi-um Grav. ; 

 the general facias is that of a large, rugose Omaliuiit. 



Eudeliplirum fjracilipalpe, n. sp. 



Moderately elongate, broad, shining, sparsely, very finely pubescent ; black, 

 the basal joints of the antennae, and the tibiae and tarsi, obscurely rufescent, 

 the femora and palpi plceous ; head and prothorax uneven, coarsely, closely 

 jiuuctured, the head almost smooth in front, the elytra coarsely, confusedly 

 punctate, with indications of smooth raised lines ou the disc, the abdomen 

 alutaceous and minutely punctulate. Head rather small, short, narrowly, sub- 

 augularly extended on each side behind ihe eyes, and deeply excavate in front 

 of them and between the ocelli, the eyes rather lar;:e ; anlennue long, slender,
