Trochilium (Sciapteron) simulans Grote. 



S . Antennae rather short, stout, black, slightly bluish, brown at tips 

 beneath. Head black with a yellow stripe on each side of the clypeus, 

 bordering the eyes in front. Palpi ascending, concealing the front,

 low hairs between the antennae. Collar yellow behind. Thorax black; 

 a yellow spot at insertion of primaries and another beneath. A yellow

 l^atch on the thorax behind. On each side of the metathorax are 

 patches of yellow hairs. Abdomen golden yellow above, with the basal 

 segment and part of the second ring black. The segments are very 

 narrowly black anteriorly and there is a mesial row of black dots not 

 very noticeable. Legs yellow ; tarsi fulvous 5 middle and hind femora 

 shaded with black ; coxae marked with yellow. Abdomen beneath with 

 the segments half black and yellow ; anal hairs yellow over black and 

 tipped with fulvous. Fore wings stained with brown ; costal edge

This species is more wasp-like than any other Korth American species 

 known to me. It is quite different from Denudatum or Marginatum. It 

 may be known by the stout yellow abdomen and the absence of discal 

 marks on the wings. In various papers I have described the following 

 species of North American Aegeriadae :

 Bailey, N. Am. Ent. 1, 17 ; Kellicott, Can. Ent. 13, 7. 



]Sr. B. — This species has the sexes much alike ; the discal bar of fore 

 wings is narrower and the head smaller than in the male exitiosay which 

 it much resembles.

$ . I have several specimens of a Psychid (?) form which I cannot find 

 in the books, and in collections the species is always unnamed. The
