;i910 THE BUTTERFLIES OF NEW ENGLAND. 



ceptins at the apes and on the apical half of the basal joint of posterior pair, whitish ; 

 the anterior femora more or less piceous and the intermediate tibiae often tinged with 

 testaceons. Wings hyaline, the veins white ; the stigma, strongly in contrast, piceous ; 

 tegulae tipped with piceous. Antennae of the $ scarcely shorter than those of the $ . 

 Mesothorax opal^e, the punctures sliallow and obscure; metathoras opake, without 

 distinct sculpture, its upper face limited on each side by a carina exterior to the 

 spiracles, a few slight ridges at the apex. Abdomen without punctures, lateral mar- 

 gins of the basal joint dark piceous, the central portion broad and with sharply deflued 

 sides; second joint with a broad, triangular central area marked off by two deep 

 grooves which diverge from the middle of the anterior margin ; ovipositor concealed. 

 Tlie radius forms with the basal vein of theareolet only a slight curve, but in one or 

 two specimens there is a slight angle on the outer side at their point of union." 



Since the description was published I have received two other specimens, 

 one reared from nicippe, by Mr. William H. Edwards and one from Eurymus 

 eurytheme by Mr. David Bruce in Colorado. The species is well marked 

 especially by the sculpture of the second abdominal joint. The cocoons 

 vary. Those from wliicli my specimens were ol)tained are either dingy 

 gray or pale yellowisli, the former with five tolerably marked longitudinal 

 ribs, the latter almost smooth. That from Mr. Edwards is intermediate. 



Genus MICROGASTER Latreille. 



Maxillary palpi 5-, labial 3-jointed. Eyes villose. Antennae IS-joiuted. Mesopleu- 

 rae rarely with a rugulose fovea. Abdomen sessile; sutui-iform articulation distinct. 

 Radius of tlie fore wing almost complete; three arbital areolets, the 2d often imper- 

 fect. Hind coxae elongate ; spurs of the hind tibiae not shorter than half the meta^ 

 tarsus. Terebra more or less exserted. (After Marsliall.)

Parasitic on Vanessa atalanta.

This species was described by Dr. Packard from specimens bred by Mr. 

 Scudder from Vanessa atalanta. Its characteristics from the material 

 before me, rather than from the original descrijition, are as follows : 



Average length, t mm. ?: Body black. Antennae brownish-black; palpi pale 

 yellow. Wings witli the stigma and veins brown. All coxae black ; all trochanters 

 black at base and yellowish at tip ; front and middle femora, tibiae and tarsi honey 

 yellow ; the tarsi dusky at tip ; hind femora and tibiae honey-yellow and dark at tip ; 

 hind tarsi dusky throughout. Abdomen with dorsum of joints 1 and 2 strongly ru- 

 gose, the rugosity on joint 1 having a tendency to form into irregular, longitudinal 

 lines toward the outer hind angles, tlie median carina being obsolete but with a 

 decided elevation or tubercle on the hind border; anterior portion of joint 3 very 

 slightly punctate ; ovipositor quite long, reaching when extended beyond the length of 

 tlie wliole abdomen ; the sheaths dark, quite pilose and two-thirds as long as abdomen. 

 Venter with a large, honey-yellow spot each side at base. 



Three females are before me from Mr. Scudder.
