NO. 2018. SYNOPSIS OF GENERA OF A0R0MY7ADJE—MALL0CH. 137 



Frons in both sexes distinctly broader than one-third the \vidth of 

 head; each orbit about one-fourth as broad as center stripe; orbits 

 shining, center stripe opaque; five distinct orbital bristles present, 

 the lower two directed slightly inward and backward, the upper 

 three directed outward and backward ; besides the bristles there is an 

 irregular row of hahs on orbits nearer to eye margin ; center stripe with 

 two rows of incurved haire which converge slightly toward anterior 

 margin; the pair of bristles on anterior margins weak, divergent; an- 

 tennae in male very large, the third joint subquadrate and very densely 

 pilose; in female the third joint much smaller and rounded at apex; 

 arista with the basal two joints distinctly thickened, their junction 

 with the terminal part slightly geniculated; pubescence on arista 

 distinct; length of arista twice as long as breadth of third antennal 

 joint in male, and about three times as long as breadth of third joint 

 in female; face black, concave in profile, in both sexes somewhat 

 produced at mouth margin; cheeks brownish, marginal bristles dis- 

 tinct, vibrissa not much differentiated; palpi black, as long as pro- 

 boscis m male, slightly shorter in female, the surface bristles sparse; 

 proboscis brown, chitinized. Mesonotum with four distinct pairs of 

 dorso-central bristles, the front pair very close to anterior margm; 

 the pair of bristles between the posterior pair of dorso-centrals dis- 

 tinctly differentiated from discal setulae; basal pair of bristles on 

 scutellum much weaker than apical pair. Abdomen with numerous 

 surface setulee, which are longer on the apices of segments. Legs 

 covered with short hairs; mid tibia with distinct apical spurs, the 

 other pairs without any distinct spurs. Wings clear; vems yellowish 

 or brownish; subcostal vein very indistinct; first costal division about 

 one-fifth as long as second; second and third veins slightly conver- 

 gent, third and fourth slightly divergent at apices; outer cross vein 

 at slightly beyond whig middle, at little more than its own length 

 from margin of wing, and at distinctly more than its own length from 

 inner cross vein. Halteres yellow. 



Length. — 2-2.5 mm. 



The only specimens of this species that I have seen from America 

 are one female from the Burgess collection, taken at Beverly, Massa- 

 chusetts, October 9, 1871, and one in C. W. Johnson's collection from 

 Orrs Island, Maine. There are two males and one female in the 

 collection from Italy (Prof. M. Bezzi) with which the American 

 specimens agree so closely as to leave no doubt as to their identity.
