151: Prof. M. Bezzi on Indian Pyrgotlnge. 



Ill some material (from India and W. China) of the Indian 

 Museum before me I find tour species^ one of wliich is new 

 to science ; and in other material, collected hy Prof. A. D. 

 Jmnis in the Himalayas, I find three very large species, 

 one of which is representative of a new genus. My thanks 

 are due to Dr. Annandale and to Prof. Imms for having 

 ])hiced at my disposal for study such important material, 

 wliicli is now to be found partly in the Indian Museum and 

 partly in the British Museum. 



I will here call attention to the fact tliat the subfamily 

 Pyrgotinse is, perhaps, not devoid of economic importance — 

 indeed, a North-A.mericau species has been recognized as 

 j)arasitic upon Coleoptera Lamellicornia ■^. The striking 

 resemblance of these strange tiies with the Oonopidse is again 

 turther confirmed by these parasitic habits. They are, 

 perhaps, of nocturnal habits, as some of the Indian specimens 

 were caught- at light; the European Ad. courctata was, 

 however, observed by Prof. Handlirsch flying in the sunshine. 



I give the following key for the determination of the Indian 

 Pyrgotin.'e known to me ; it must be remarked that the 

 species no. 2 is from Ciiina : — 



1. (2) Auteunal grooves coalesceut, forming 



a single very deep cavity ; scutellum 

 entirely bare, with only a pair of 

 erect bristles at the posterior end ; 

 all the femora below towards the 

 apices armed with a double row of 

 rather strong bristles ; second longi- 

 tudinal vein with a prteapical 

 stump ; anal vein complete to the 

 end ; posterior cross-vein very ob- 

 lique, and therefore the inferior angle [Hend. 

 of the discal cell very acute t .... l..Api/rffota pictive?itris, 



2. (1) Antenual grooves well separated by a 



prominent complete keel ; scutellum 

 usually haired, and when bare the 

 marginal bristles are at least two 

 pairs ; femora unarmed. 



3. (12) Third longitudinal vein ending at the 



apex of the wing ; ovipositor with- 

 out a strong basal tubercle. 



4. (9) Anal vein very short; second longi- 



tudinal vein usually without a 

 stump or rarely provided with a very 



* Pyrgota nndata, Wied., on Lnchnosterna, by S. A. Forbes. 



t In all the species here described the costa reaches the end of the 

 fourth longitudinal vein, but after the end of the third it is very thin and 

 often hardly distinct.
