6. — Astatus pygidialis Fox. 

 Astatus pygidialis Fox, Can. Ent. p. 234. 9. L892. 



9 . — Produced portion of anterior margin ofclypeus subtruncate; 

 front with tolerably strong punctures which become sparse medially 

 and laterally; vertex with strong, sparse punctures; first joint of 

 flagellum about one- quarter longer than the second; dorsulum punc- 

 tured about like the front, perhaps a little more finely so; scutellum 

 sparsely punctured, not impressed ; upper surface of metathorax 

 coarsely reticulated, with a prominent, longitudinal, medial ridge, 

 at the apex is a strong depression, the metapleune and posterior face 

 rugose ; tibiae and tarsi strongly spinose; abdomen scarcely punctured; 

 pygidial area about twice as long as it is broad at the base. Black ; 

 abdomen entirely red; mandibles in middle ferruginous; tegular and 

 legs testaceous; head, thorax and legs with white pubescence ; wings 

 subhyaline, the apical margins broadly fuscous; marginal cell ob- 

 liquely truncate; stigma yellow. Length 8-10 mm. 



New Jersey; Texas. 



7. — Astatus nevadicus Cress. 

 As/a/a nevadicaQr., Proc. Ent. Sect. Acad. Nat. Sciences Phila. 1881. p. V. 9 •

9 . — Produced portion of anterior margin of clypeus subtruncate; 

 front with deep and sparse punctures, which become closer towards 

 the clypeus; vertex with tolerably large sparse punctures; antenna? 

 short and stout, the first joint of flagellum scarcely one-quarter longer 

 than the second; dorsulum very sparsely punctured, polished; scut- 

 ellum likewise and not impressed; upper surface of metathorax with 

 the reticulum tolerably coarse, but finer than in pygidialis orbicolor, 

 depressed at the apex in the middle, and without a central, longi- 

 tudinal ridge, metapleurre coarsely striated; legs stout; tibiae and 

 tarsi strongly spinose; abdomen almost impunctate; pygidial area 

 possibly a little more than twice longer than it is broad at base. 

 Black; abdomen entirely red; mandibles medially, tegulae and tarsi 

 reddish testaceous; face, clypeus and dorsulum anteriorly with 

 black pubescence ; cheeks, occiput, thorax and legs with white pu- 

 bescence; wings subfuscous, the apical third fuscous; marginal cell 

 obtusely truncate. Length 8-9 mm. 



S . — Produced portion of anterior margin ofclypeus as in the 9 ! 

 first joint of flagellum about one-third longer than the second; dor- 

 sulum anteriorly, finely and evenly punctured, sparsely so poster-
