366 THE CANADIAN ENTOMOLOGIST, 



posterior metatarsus shorter than the four following segments together ; 

 the claws with a minute erect tooth at middle. Type, Taxoiuis albido- 

 pictus, Nort. 



Taxonus, Htg. — This genus was described by Hartig in Die Familien 

 der Blattwespen und Holzwespen, Berlin, 1837. The following species 

 were included: Nitida, Kig. { = agronim, Fall); stricta, Klg.; bicolor, 

 Klg., and coxalis, Htg. { = €qtiiseti, Fall), and agilis,Yi\g. ( = glabratus, 

 Fall). So far as I have been able to determine, no type has been indicated 

 for this genus, and in order that the same group of species may be retained 

 in the genus, equiseti, Fall, should be taken as type. 



Taxonus montanus, MacG. — The unique male type of this species on 

 careful study and comparison proves to be the same as Epitaxonus 

 albidopictus, Nort. 



Taxonus floridatius, Pro v. — This is a synonym of Fseudosiobla 

 robusta, Kirby. 



Taxonus unicindus, Nort. — From a careful study of all the material 

 at hand, I have come to the conclusion that Taxonus tmicinctus, Nort.; 

 Strongylogaster pallicoxus, Pro v., and Taxonus boreaiis, MacG., are all 

 one and the same species. Norton's name is the older and should be 

 used ; the species belongs in Ashmead's genus Strongylogastroidea. 



MoNOSTEGiA, Costa. — This genus, as near as it is possible for me to 

 determine at this time, was proposed by Costa to include luteola. Klg. 

 ( = abdominalis, Fab.). Fabricius's species is readily separated from 

 Poecilostoma by having the claws bifurcate at apex. The name Afono- 

 stegia is used here in its original sense, and abdominalis, Fab., is taken as 

 its type. 



Monostegia Martini, n. sp. — Black, with the following parts rufous: 

 the labrum, the collar broadly, the tegulae, the metathorax, the abdomen, 

 the legs, and the base of the wings ; the second segment of the antennae 

 as long as the fourth and fifth together ; the frontal ridge wanting and 

 the antennal fovea and the ocellar basin united. Length, 7 mm. 



Habitat. — Westfield, Mass., J. O. Martin collector. 



Phrontosoma, n. gen. — Front wings with the second abscissa of Cu 

 subequal in length to the free part of M^ ; the free part of 2nd A oblique ; 

 the hind wings with the cell Rj^o always with a distinct appendage at 

 apex ; the posterior metatarsus never longer than the four following 

 segments ; the claws cleft, with the inner lobe not more than one-half the 

 length of the outer lobe. Type, Phrontosoma atrum, MacG.
