In all loo records for Odonata were obtained; 85 of these are 

 new, i. c. all those from all localities at which any collecting was 

 done excepting Oueretaro, Jalapa and Xico. The 100 records 

 represent 43 species, 31 species being taken or identified from 

 the localities visited north of the twenty-first parallel of north 

 latitude. This number does not indicate a very rich Odonate 

 fauna for the northern Mexican plateau, although, no doubt, 

 many additions are yet to be made to the list. 



The Male of Comperiella. 



By L. O. HOWARD. 



In Entomological News for April, 1906, pp. 121-122, under 

 the heading "An Interesting New Genus and Species of 

 Encyrtidae," I described Cornpcriclla gen. nov. bifusciata sp. 

 nov. from one female specimen bred from Aspidiotus (Aoni- 

 diella) aurantii Maskell, collected in China by Mr. George 

 Compere. Since that time, Mr. E. K. Carnes has bred the 

 male in the insectary of the California State Horticultural 

 Commission at Sacramento, California, and has sent me a 

 single slide mount. It may be described briefly as follows :

 joint i twice as long as pedicel and about equal to 2 ; 3 and 4

 pedicel joints 5 and 6 together; entire flagellum, with whorls 

 of long curved hairs. Abdomen shorter than thorax and flat
