NO. 1869. NEW SPECIES OF WASPS— ROHWER. 451 



carina medially; angles of propodeum nearly cylindrical, long; 

 abdomen with well separated, distinct punctures, which become 

 smaller posteriorly; first dorsal segment slightly emarginate anteri- 

 orly when seen from above; second and third dorsal segments 

 depressed basally for about one-third; apical ventral segment Avith 

 the large punctures well separated; second cubital cell on the radius 

 as long as two-thirds of the distance between the recurrent veins. 

 Black except where mentioned; antennse rufo-piceous; posterior 

 orbits dorsally, narrow line on inner orbits up to and filling the eye 

 emargination, large spot on clypeus, spot above, posterior margin of 

 pronotum narrowly, and an elongate lateral spot, large spot below 

 tegulse, tegulse, spot above, large spot in front of depression on meso- 

 scutum, most of scutellum, angles of propodeum, dorsal and ventral 

 (except first) abdominal segments apically yellow; pronotum (except 

 where mentioned), band on scutellum, elongate spots on second, 

 third, and fourth segments rufous; legs rufous; Avdngs dusky, espe- 

 cially near the veins; stigma and costa reddish-brown, veins dark 

 brown. 



The second female has more red on the three abdominal segments. 



The female "will fall next to texanus, from which it will easily be 

 separated by the depression of the second and third dorsal segments. 



If the sexes prove to be wrongly associated, the species should 

 stand with the male as type. 



New Mexico, Albuquerque. One male on flowers of Phacelia neo- 

 mexicana May 13, 1910, collected by Mr. J. R. Watson. Mesilla, one 

 female collected May 29 at flowers of Phacelia by Prof. T. D. A. 

 Cockerell (Oockerell No. 5368). Filmore Canyon, one female col- 

 lected August 28 by Prof. T. D. A. Cockerefl. 



Type.— Cat. No. 14143 U.S.N.M. 



PSEUDOMASARIS ALBIFRONS, new species. 



IfaZe.— Length about 12 mm. Very like texanus (Cresson), from 

 which it may be separated by the following characters: Very few 

 large punctures on the front and these not sharply defined; posterior 

 part of mesoscutum uniformly punctured (in texanus the depressed 

 area is more closely punctured); punctuation of abdomen finer; sec- 

 ond dorsal segment depressed by fully half its entire length (in tex- 

 anus it is hardly depressed) ; third segment hardly depressed (in 

 texanus it is depressed by fully one-third) ; punctures of the apical 

 dorsal segment more widely separated; second cubital cell on the 

 radius longer, being in the type greater than the distance between 

 the recurrent veins (in texanus it is much less); markings whitish; 

 Clypeus except apical part pale; wings slightly yellowish in stigmal 

 area, otherwise hyaline.
