1884 THE BUTTERFLIES OF NEW ENGLAND. 



joint 1, first four-fifths of joint 2, and first one-fourtli of joint 3, its entire surface 

 covered witli very sliort pile. Punctation of liead and mesonotum identical, fine and 

 close; metanotum with a more rugose punctation, and with a faint median, longitudi- 

 nal channel; two diverging carinae arise each side of this median channel, at front of 

 metanotum, and meet two converging carinae at half tlie length of this sclerite. 

 Length, 8 mm. ; expanse, 12 mm. 



Described from two male specimens, both reared from Basilarchia 

 arcliippus, by Mr. W. H. Edwards, at Coalburgh, W. Va. One is 

 labelled July 15, 1886, and of the other Mr. Edwards writes that it left 

 the archippus larva at the latter's second moult. The cocoons of both in- 

 dividuals were also sent by Mr. Edwards. They are (3 mm. long and 

 2.5 mm. broad, of a regular oval shape and spun of grayish white silk ; 

 near either end is an irregular, interrupted black band, and upon each end 

 are three or more black spots. , 



Genus PIMPLA Fabricius. 



Head transverse, short, cheeks not swollen ; clypeus distinct, depressed or subex- 

 cavated at apex; antennae porrect, filiform, scape excised at apex; eyes oblong, emar- 

 ginate near base of antennae. Thorax robust, moderately elevated ; scutellum with an 

 obtusely rounded apex; metanotum low, spiracles oval or circular; tarsal claws 

 simple, sometimes lobed at base with female; areolet of fore wings always complete, 

 triangular. Abdomen sessile ; in females of most species oblong or oblong-ovate, in 

 males narrower, subcylindrical or sublinear ; narrower than the thorax or very slightly 

 broader, strongly, or faintly and thickly punctate; joints 2 to 7 usually transverse, 

 sometimes subquadrate with the males, the ventral border of the two last with the 

 females longitudinally fissured; joint 1 subquadrate, or scarcely longer than broad, 

 rarely slightly shorter, usually with a longitudinal carina. Terebra usually shorter 

 than abdomen, but may equal it in length or exceed it. 



Pinipla annulipes BruUe. PI. 88, fig. G. 



Male, female.— The head is sparsely and finely punctate, especially on the face, 

 which is sometimes so pubescent as to appear opaque, and sometimes has the pubescence 

 mostly removed so as to appear subpolishcd. A minute, glabrous tubercle on the disk 

 of the face. The palpi are generally dull, dark rufous in '? , sometimes pale rufous, 

 sometimes almost whitish, but in the $ they are always whitish; the auteunae are 

 about four-fifths as long as the body; the 1st joint of flagellum in <J , 3-3i times, in ? , 

 4-5 times as long as wide, the entire flagellum, g $ , tinged with rufous l)eueath. The 

 thorax is finely and sparsely punctate above and below, and the metathorax is conflu- 

 ently and rather coarsely punctate, and usually more or less covered with fine, whitish 

 pubescence so as to be opaque ; the posterior declivity and a small area behind the 

 scutel glabrous and polished, the two glabrous areas never quite confluent. Carinae all 

 obsolete, except a small basal portion of the two central ones. The abdomen is con- 

 fluently punctate and opaque; the usual tubercles are subobsolete, and the sides and 

 extreme tips of the intermediate joints are often more or less tinged with sanguineous 

 in ? , sometimes conspicuously so, but never in ,J . In joint 1 the usual carinae scarcely 

 extend halfway to the tip, and enclose between them a glaljrous, circular, subbasal ex- 

 cavation. The ovipositor is half as long as body ; the sheaths pubescent, scarcely 

 tapered, and basally rather narrower than the last tarsal joint of "the hind legs. Venter 

 dull rufous, blackish at tip, sometimes all blackish, except extrenae base. The legs 

 are pale bright rufous, but in the front legs of more than one-fourth of the J <? the 

 trochanters are whitish ; in the middle legs <f ? , the second fourth of the tibiae is 

 whitish, and very rarely the first fourth and the terminal half blackish exteriorly; and
