THE CANADIAN ENTOMOLOGIST. 155 



at basal third ; sides rapidly convergent toward base and deeply sinuate 

 at the basal angles, the latter right ; apex feebly sinuate, but slightly nar- 

 rower than the base and two-thirds as wide as the disk, the latter feebly 

 impressed along the basal margin, feebly explanato-reflexed at the sides, 

 and coarsely, very closely punctate, the punctures sparser near the centre. 

 Elytra nearly one-half longer than wide, distinctly more than twice as 

 long as the prothorax, at base not as wide as the disk of the latter ; disk 

 coarsely, not very closely, unevenly punctate, with tolerably uniform but 

 unevenly impressed series of coarser punctures. Legs moderate in length, 

 rather slender ; femora remotely punctate ; tibiae slender, not much wider 

 at apex, with impressed series of asperate punctures, seriately setose; tarsi 

 short, stout, but slightly more than one-half as long as the tibiae. Hypo- 

 mera coarsely and scarcely confluently punctate, very inconspicuously 

 setose. Length, ii.o mm.; width, 5.0 mm. 



California. 



Differs radically from Keeni in the structure of the antennal club and 

 tibiae. It is related to californictis, but differs conspicuously in its obese 

 form and larger prothorax, and also in its coarser and much denser 

 sculpture throughout. The types of both this species and Keeni are 

 apparently females. 



NOTES ON HYMENOPTERA. 



BY W. HAGUE HARRINGTON, F. R. S. C, OTTAWA. 



The advent of another collecting season finds me with a very large 

 proportion of my last year's captures still undetermined, and in many 

 instances even unexamined. A few remarks, however, in regard to my 

 success with the Hymenoptera may induce some of our younger members 

 to pay more attention to this order. Probably 500 species were collected, 

 a large proportion of which were of the smaller forms, and it seemed, 

 indeed, that many of the larger species were much less numerous than in 

 some seasons. Special attention was given to the collection of the micro- 

 hymenoptera, for these are so poorly represented in Canadian collections. 

 In making a rough summary of the species, I find about 125 species 

 belonging to the Aculeata, and 100 to the Phytophaga., the remainder 

 being distributed among the different families of parasitic 

 forms. There are many interesting additions to my collection, and 

 many gaps have been filled in. Mr. Ashmead's monograph of the 

 Proctotrypids has made it abundantly evident that the knowledge of the
