In the review in Nature on Volume I of my " Hymenoptera of India," 

 issued as one of the " Fauna of India" series, the writer remarked that 

 close on one thousand species of wasps and bees are described in that 

 volume, and stated that probably more thjin two thousand 

 species would ultimately be found within the limits treated 

 of in my work. This forecast seems more than likely to come true. 

 in a collection of Hymenoptera recently made at Deesaand at Simla by 

 Captain C. Nurse, and kindly sent to me to work out, I find among the 

 bees and wasps alone no less than 23 species new to the Indian fauna, 

 out of which number, so far as I can make out, 22 species have not 

 hitherto been described. 



I give below a description of these as well as of a few presumably 

 new species of Tenthredinidce, Ichneumonidce, and ChrysididcB , received 

 some from Mr. F. Moller, of Tukvar, Darjiling, and some with the bees 

 and wasps collected by Captain C. Nurse in Simla and Deesa. My 

 best thanks are due to both these gentlemen for their kind loan as well 

 as presents of collections. 



Family TenthrediniD^e, Leach.

 clypeus, the posterior angles of the pronotum, the apex of the scutel- 

 lum, a spot above the posterior cox?e on each side, the anterior femora 

 and tibi?e in front, and a broad line widening laterally at the base of the 

 abdomen, lacteous-white ; the apex of the posterior femora, the posterior 

 tibise, and the apical margins above of the 3rd to the 5th abdominal 

 segments ferruginous-red; wings hyaline, the front wing anteriorly
