no. 1837. NEW SPECIES OF WASPS— ROHWER. 583 



furrow from the base to almost the apex; posterior face granular 

 with a few transverse striae, the upper margin with a distinct trans- 

 verse carina; sides granular; legs rather robust, but not very strongly 

 spined; tarsal comb of short bristles as in Tachytes; the inner cal- 

 carium of the posterior tibiae not as long as the basitarsus; third 

 cubital on radius equal to a little longer than the second; abdomen 

 shining, finely reticulate; pygidium well defined, apparently twice as 

 long as broad at base, smooth, with a few scattered punctures, rounded 

 at the apex. Black; palpi, tegulae, apecies of tarsi and calcarium 

 reddish testaceous; head, thorax, and abdomen with short white pile; 

 wings distinctly dusky, especially at the tips; venation pale brown. 



Lee County, Texas. Collected May 10, 1898. Collected by Rev. 

 G. Birkmann at the town of Fedor. 



Type.— Cat. No. 13764, U.S.N.M. 



The pygidium of the paratype is reddish, and the furrow of the 

 propodeum is not so distinct, the striate being longer. 



Related to Larroj)sis tenuicornis (Smith), but may be separated by 

 the greater space between the eyes at the top, and the sides of pro- 

 podeum not being striate. 



LARROPSIS PORTIANUS, new species. 



In Fox's table to the species of Ancistromma this species runs to 

 conferia Fox, but is quite different from that species. The male has, 

 judging from the description, a superficial resemblance to L. tachy- 

 sphecoides (Viereck), but the distance between the eyes at the vertex 

 is not as great as in that species. 



Female. — Length 7.5 mm. Anterior margin of the clypeus sub- 

 truncate, very slightly emarginate, with two lateral teeth, the outer 

 tooth the larger, surface with small, distinct, separated punctures, 

 some larger ones near the anterior margin; front with close, distinct 

 punctures, vertex with the punctures somewhat more separated; an 

 impressed line from anterior ocellus to between bases of antennae; 

 depression behind the lateral ocelli triangular in outline, with a 

 longitudinal impressed line in the middle; space between the eyes at 

 vertex a little greater than the length of second and third antennal 

 joints; antennae robust, scape large, not as long as the two following 

 joints, pedicellum but longer than wide, third and fourth joints sub- 

 equal in length; mesonotum and scutellum with rather large, distinct, 

 well-separated punctures; scutellum indistinctly impressed; meso- 

 pleurae granular; dorsal aspect of propodeum with a broad, shallow 

 median furrow, striato-granular, the striae poorly defined, oblique 

 from center; posterior face sculptured like dorsal aspect with an 

 acute median triangle, the point downward; sides of propodeum 

 with the striae stronger than on the dorsal surface ; legs strongly 

 spined, the inner calcarium of posterior tibiae longer than the basi-
