CREMASTUS (ZALEPTOPYGUS) GRANULATUS Davis. 



Cremastus granulalus Davis, Trans. Amer. Ent. Soc, vol. 24, 1897, p. 365, female, 

 male. 



In the type series of this species, consisting of four females and 

 one male, there are apparently three species confused. The female 

 bearing the name label and further labeled "Ag. Coll. Mich., 6.8.92- 

 209," is hereby designated as the holotype. This specimen runs 

 in the key to similis Cushman and differs from the description of 

 that species only in the second tergite not being parallel-sided but 

 slightly divergent, and in the abdomen being entirely black. Com- 

 parison of the types would undoubtedly show other differences. 



CREMASTUS (ZALEPTOPYGUS) NEMORALIS Davis. 



Crejnastus nemoralis Davis, Trans. Amer. Ent. Soc, vol. 24, 1897, p. 364, female, 

 male. 



In my ke}' to females the type runs to the second alternate of 

 couplet 20 on account of its nearly black hind coxae, but it is really 

 more closely allied to the group of species under the first alternate. 

 In this placing it runs on most of the characters to similis Cushman, 

 from which it differs as follows: Petiolar area much broader than 

 areola, latter distinct]}^ more than half as broad as long; first tergite 

 longer than second; second tergite broader, sides weakly divergent; 

 ovipositor longer than abdomen; abdomen black throughout; 

 scutellum black; hind legs mostly dark, coxae and femora piceous, 

 tibiae and tarsi fuscous, trochanters, apices of coxae, and base and 

 apex of femur whitish. 



The male runs to the second alternate of couplet 9, but is more 

 closely allied to the species falling under the first alternate, where it 

 agrees best with tetralophae Cushman. Differs from female in having 

 scutellum more or less reddish; yellow color of pronotum extending 

 into notauli; middle tergites somewhat reddish; e3^es and ocelli 

 larger but not extremely large; diameter of lateral ocellus equal to 

 postocellar line, which is a half longer than ocell-ocular line; face 

 entirely yellow. 



CREMASTUS (ZALEPTOPYGUS) ORBUS (Davis). 



Leptopygus orbus Davis, Trans, Amer. Ent, Soc, vol, 24, 1897, p. 365, female, 

 male. 



Both sexes run in my key to ohereae Viereck, differing in the key 

 characters only in having the wings hj^aline. 



The two following new species are remarkable for the very short, 

 stout thorax with the mesoscutum broader than long and the areola 

 hardly half as long as the petiolar area. On these characters and the 

 pectinate claws they run in Szepligeti's key ^ to Celor Semenow, 



I Gon. Ins., fasc. 34, 1905, p. 49.
