726 Dr. R. C. L. Perkins on 
specimens were in need of cleaning, and some specimens, 
not of much importance, were in process of destruction 
from the formation of verdigris. 
Odynerus hawanensis, Bl. Under this name a number 
of species were confused. As mentioned in the “ Fauna 
Hawaiiensis,” a specimen sent to me by Mr. Blackburn, as 
representing this species, was a female of Pscudopterocheilus 
pterocheiloides, and I suggested that O. hawatiensis might 
really be my O. erythrognathus. As a matter of fact, five 
of the twelve examples are evythrognathus. The individual, 
however, which bears the type label, is unfortunately the 
very distinct 0. venator, and as this individual is specially 
referred to in the original description as being a variety, 
it seems doubtful whether it can be accepted as the type 
of the species. If the name “ hawaiiensis” be accepted 
at all, it should, I think, sink my species 0. erythrognathus 
rather than O. venator, in spite of the type label. On the 
other hand, the description of O. hawawensis was made 
from a series of such different species that one may well 
doubt whether it ought not to be disregarded. Thus five 
specimens, as above mentioned, are my Odynerus erythro- 
gnathus, one, the type, is O. venator, one is O. thersites, three 
are Pseudopterocheilus pteracheiloides, one 1s Chelodynerus 
chelifer, and one is Nesodynerus egens. The confusion of 
species 1s due to the fact that Mr. Blackburn followed 
Smith in his system of description of the Hawaiian 
Hymenoptera, and paid no attention to the mouth parts, 
mandibles, second abdominal ventral segment, and the 
tibial spurs. 
Odynerus vulcanus, Bl. The examples referred to as 
varieties are O. konanus, P. 
O. haleakalae, Bl. This, or rather the type, is, as I 
suggested, my O. ecostatus, but it also included one 
O. lanatensis, P., and one O. laevisulcatus, P. 
O. agilis, Smith. Now known as 0. smithii, D.T., the 
name agilis having previously been used by Smith in the 
genus. The Blackburnian series consists of O. smithii 4, 
O. socialibus many, O. scoriaceus 2, O. peles 1. 
O, dubiosus, Sm. The types are as identified by me, 
but Blackburn’s specimens included 0. pterophaennes, P. 
O. insulicola, Bl. The series contained one Nesodynerus 
cooki, P., or a form representing that species on Mau. 
0. kirbyi, D.T. (=O. extraneus, Kirby) is represented 
by one O. kauaiensis, P., only.
