Dasi'tes PaykuU. 



This genus, as might be expected, is well represonted in th,e T^^ima- 

 laya ; twelve species are contained in the collections before me, twc of 

 these having been found in abundance on flowers in Kumaon. Oi ^ 

 species, D. aitrescens, in the absence of the S , is provisionally included 

 in Dasytes ; the others have a small fourth tarsal joint, as in Dasytiscus. 



1 (10) Tarsal joints 1-3 broader than 4, the latter small ; elytral ii: u-gius nut 



explanate. 



2 (9) Antenna] joints 5-8 equal or subequal in width ; elytra longer. 



3 (4) Prothorax longer, sometimes canaliculate ; body elongate, metallic 



green, the legs and antennae black Species 1. 



4 (3) Prothorax shorter, not canaliculate ; body less elongate, aeneous, 



nigro-aeneous, or aeneo-piceous, the elytra wholly or in part testa- 

 ceous in No. 2. 



5 (8) Elytra without intermixed smooth raised points. 



6 (7) Legs in great part testaceous Species 2-6. 



7 (6) Legs black Species 7, 8. 



8 (5) Elytra with intermixed smooth raised points ; legs testaceous 



Species 9. 



9 (2) Antenna! joints 5-8 unequal in width ; elytra shorter ; legs inf uscate : 



species very small Species 10, 11.

Eighteen specimens of this species are before me, varj-ing in the 

 intensity of the puncturing of the prothorax and elj'ti-a and in the 

 development of the median channel on the prothorax, which in some 

 examples is complete and well-defined and in others nearly or quite 

 obsolete. An elongate, metallic -green insect, with the legs and antennae 

 black ; the prothorax longer than broad, narrowed and somewhat con- 

 stricted anteriorly, and very sparsely punctured on the disc in d ; the
