126 CHAS. T. BKUES. 



Described from three % specimens, bred in an artificial nest from 

 a mixed colony of Myrmica and Leptothorax at Colebrook, Conn., 

 August, 1901. 



Caloteleia Marlaltii Asfam. 



I have numerous specimens of this widely distributed species 

 which were bred by Dr. Win, M. Wheeler in a mixed nest of Myr 

 mice and Leptothorax at Colebrook, Conn., August 10, 1901, as well 

 as specimens from Woods Hole, Mass. 



All of the males have the abdomen pale at the base, and the third 

 abdominal segment smooth, otherwise they agree well with the de- 

 scription of this species. 



Hemilexodes ambigua sp. nov. 

 Female. — Length 2.5 mm. Black shining, legs and antennas, except apex, 

 rufous. Head sparsely pale pilose ; mandibles entirely rufous. Antennal scape 

 reaching about to the posterior ocelli, pedicel stouter than first flagellar joint, but 

 of equal length. Second flagellar joint scarcely more than half as long as the 

 first, then the joints become slightly shorter to the fifth which is submoniliform ; 

 following joints forming a loosely articulated, 6-jointed spindle-shaped club. The 

 apical joint more slender than penultimate, but longer. Mesonotum sparsely 

 pale hairy, with two distinct furrows. Scutellar fovea deep and broad, its sur- 

 face longitudinally fluted. Metathorax wooly, coarsely sculptured. Petiole 

 about two and one-half times as long as thick, finely longitudinally striated. 

 Abdomen very shining, black, the petiole below and the base of the second ven- 

 tral segment sometimes yellowish or rufous. Second segment twice as long as 

 the remaining segments ; the abdomen obliquely subtruncate at the apex. Legs 

 yellowish or rufous. Wings strongly fringed, ouly a slight indication of an emar- 

 gination at the apex. Stigmal vein about two times as long as the very short 

 marginal vein. Post marginal vein about half as long as the stigmal. 



Described from two female specimens, collected in a nest of Ste- 

 namma fulvum var. piceum, at Colebrook, Conn., where it, no doubt, 

 lives parasitically upon myrmecophilous dipterous larva?. 



I have been doubtful whether this species belongs more properly 

 to Hemilexis Forst, or to Hemilexodes Ashm., as it presents charac 

 ters of each, and again departs somewhat from both in the form of 

 the antenna? and venation. 



AUXOP.EDEUTES gen. nov. (see Plate I). 

 Head orbicular, much produced in front to form a sort of shelf at 

 the base of which the antenna? are inserted. Seen from the side the 

 projection is triangular, with a horizontal upper surface. Antenna? 

 12-jointed, clavate, the last two joints much enlarged, the penulti 

 mate the longest ; scape rather short, equal to the last two flagellar
