Notice of several new species of TENTHREDINID^. 

 BY ED.WARD NORTON. 



ALLANTUS Jurine. 



A. excavatus, n. sp. Length 0.39. Ex. wings 0.79 inch. 

 9- Black, edge of collar, basal plates (of metathorax) and apex of abdomen, white. 

 Antenuffi stout (as in basilaris), two basal joints white; a faint spot in middle of 

 labrum and the palpi, whitish; mandibles black; head, thorax, posterior coxae 

 and femora covered with deep pits; abdomen shining; all the upper edge of collar 

 (tegulre black), a spot beneath tegulse, basal plates, apex of abdomen and tips of 

 four apical segments above, white; a rufous spot on each side of second segment, 

 near its base; tips of coxse, trochanters, base of femora, tips of four anterior fem- 

 ora and their tibire and the posterior tibise, except at tip, white; all the tarsi slight- 

 ly rufous or blackish. Apical half of wings deeply clouded, fading into smoky 

 yellow towards centre; basal half of stigma pale. 



One specimen; Maryland. (Coll. Phil. Ent. Soc.) 



This has the lanceolate cell open, with oblique cross line, as in Marro- 

 phi/a Sec. 1, Hartig, but the femora are short, as in Allantns. 



STRONGYLOGASTER (Tenthkedo) Dahlbom. 



S. multicinctus, n. sp. Length 0.3-1. Ex. wings 0.68 inch. 

 9- Black, with whitish abdominal bands. Antennae hardly longer than thorax, 

 somewhat thickened in middle, end joint decreasing in size. Head and face dull, 

 rough with large pits; thorax and abdomen shining, the former with large scatter- 

 ed punctures; palpi pale, face black, with a few pale hairs; edges of ovipositor 

 sheath fringed with long pale hair; basal half of each segment of abdomen straw 

 colored; tips of femora, the tibise and tarsi pale reddish, posterior knees almost 

 white; anterior tibial spur bluntly bifid, posterior tibial spurs very short and 

 blunt; wings hyaline, stigma and costa pale. 



One specimen from Virginia. (Coll. Phil. Ent. Soc.) 



This agrees with Strongylogaster Hartig, Tribe 2, in its lanceolate open 

 cell and two inner underwing cells. Its " third joint of antennae longer 

 than fourth" and deeply emarginate nasus would place it in Allantus Ste- 

 vens. It resembles Str. rwgnlata of Europe. 



TENTHREDO Hartig. 



T. 14-punctatus, n. sp. Length 0.34. Ex. wings 0.68 iuch. 

 9 %■ Greenish-white, spotted with black, above. Antennae long and slender, up- 

 per side black, third joint a little longer than fourth, nasus not emarginate: tho- 

 rax irregularly marked with black above; scutellum pale; a broad stripe through 

 the middle of seven basal segments of abdomen and seven dots on each side near 

 the base of each, black; the upper side of legs black, except on the coxae, base of 

 femora and an interruption near the base of tibiae; wings hyaline, stigma and 

 costa pale ; under wings without middle cells. 



Two specimens from Virginia. (Coll. Phil. Ent. Soc.) 



The tergum of the male is irregularly marked and the black tibial line
