Besides the type, I have seen the following material of this species: 

 In the National Collection there are five specimens, reared from 

 Cirphis imipun-cta by G. G. Ainslie, at Nashville, Tennessee, under 

 Webster No. 11332C ; five reared from "■BeliopUla, species " by R. A. 

 Vickery, at Brownsville, Texas, under Webster Nos. 6451 and 6453; 

 one specimen reared from Cirphis^ at Schenectady. New York, by 

 E. V/. Searls; two reared by R. J. Kewley, at Columbia, South

 Nashville, Tennessee, by C. C. Hill; and collected specimens from

27. MICROPLITIS SCUTELLATUS, new species. 



Closely allied to rtiontanus; but differs strikingly in the black te^a-

 pitted along the sides. 



Feviale. — Ijength 3 mm. Head transverse ; face, vertex and
