two following comtrned, head orange color, with a black stain between 

 insertion of antenna; and occiput, eyes black, mandibles with dark tips 

 antennae brown to fuscous, the brown joints tipped with fuscous ;

 the former entirely and the latter mostly black, scutel, postscutel and 

 metathorax partly blackish, wings fuscous, stigma and veins blackish, 

 legs almost entirely orange yellowish and apical tarsal joint of front

 joint, more or less fuscous; abdomen with the first dorsal segment 

 joint of front legs, apical half of middle tarsi, base of hind coxae and 

 trichanters, apex of hind tibiae, hind tarsi beyond basal half of first 

 tarsal joint, more or less fuscous; abdomen with the first dorsal segment 

 blocked off into three parts by an impressed line or groove on each 

 side of-the middle half along the posterior margin, these pieces becom- 

 ing narrowed anteriorly, the laterals attaining a triangular shape, central 

 lobe of first dorsal segment partly blackish, apical one-half of dorsum

Chelonus carpocapsae, new species. 



This species is very like C. fissus, from which species as well 

 as all other species of Chelonus it can readily be separated by 

 the structure of the metathorax, which along the outer and 

 upper edge of the posterior face is produced into four nearly 

 equidistant prolongations that are nipple-shaped in outline, the 

 productions nearest the middle line are farther from each 

 other than from the outermost productions. This structure of 

 the metathorax calls to mind the structure of the apical margin 

 of the abdomen in Chrysis (Tetrachrysis) nitidula, though the 

 productions are by no means thinned out or pointed in this case 

 as in the foregoing species; scape and basal third of flagel 

 brownish, basal half of posterior tibiae mostly brownish, the 

 apical half almost black.
