segment nearly the same as that on the third, but on the fourth segment the im- 

 pressions are not so distinct and the punctures are smaller and closer together; 

 ovipositor a little longer than the abdomen. Black; clypeus anteriorly, large 

 spot on basal half of mandibles, tubercles, tegula?, base of wings, anterior coxae 

 and anterior trochanters white or whitish; otherwise the legs are brownish tes- 

 taceous, except as follows: The claws are brown, posterior tibia> and tarsi brownish 

 to a great extent, posteriorly the posterior tibiiv are whitish, except a brown 

 band near the base and a brown band at apex, posterior tarsi pale at base, the 

 metatarsus with the basal fourth pale; ovipositor of the usual color. Middle 

 trochanters also somewhat whitish.

Cryptus (Mansa?) politicalypterus, n. ep. 



Generically also like Opisoxeetus, except in length of eubmedian cell and 

 mesonotal furrows, and in the character of the metathorax. Very like the Crea- 

 sonian interpretation of C calipterus Say, from which it differs in the more 

 separated sculpture, the shining integument, and in the absence of a transverse 

 carina on the metauotum. 



Male. — Length, 11 mm. Head lengthened; face dullish, closely sculptured, 

 clypeus and supraciypeal space distinctly elevated; front, vertex and cheeks 

 more shining, the cheeks and anterior margin of clypeus especially so; space be- 

 tween lateral ocelli greater than the space between a lateral ocellus and the an- 

 terior ocellug, less than the distance between lateral ocellus and nearest eye 

 margin; malar space higher than the mandibles are broad at base, about as high 

 as half the length of the first joint of the flagellum ; antennaj thirty-nine jointtd, 

 scape very broad, together with the pedicellum a little shorter than the first 

 joint of the flagellum. Thorax rather shining; dorsulum with the parapsidal 

 grooves rather shallowly impressed on the anterior half of the sclerite, punctures 

 separated, but not far apart, minute, and rather inconspicuous; scutellum 

 rather strongly punctured in comparison with the dorsulum; pleura with dis- 

 tinct, separated punctures on a shining surface, those of the mesopleura most 

 distinct, the punctures of the metapleura almost adjoining ; metanotum separated 

 from metapleura by a shallow furrow in which there is no raised line, metanotum 

 punctured and shining nearly like the metapleura but uneven, the superior face 

 partly flat, the posterior face broadly, shallowly excavated ; wings colored as in 

 calipterus; the areolet pentangular, the radial side and the transverse cubiti of 

 nearly equal length, the first cubital side as long or a little longer than the first 

 transverse cubitus, the second cubital side a little more than half the length of 

 the first cubital side; transverse median nervure in posterior wings broken a little 

 below the middle. Abdomen smooth land shining. Head and dorsulum covered 

 with short, rather abundant, golden pubescence; abdomen pubescent, much 

 like the face and dorsulum; clypeus in part and metathorax with long, erect 

 pubescence of a golden tint; antennae dull and rather densely covered with short 

 pubescence; pleura with erect, rather long, inconspicuous pubescence. Rufo- 

 testaceous; inner eye margins yellowish; mandibles at tip, claws and apical 

 tarsal joint more or less brown ; abdomen, except petiole, and antennae to a great 

 extent dark ferruginous, apical fourth of antennse brownish; posterior legs
