specimens at hand of both obesus and chapad have them 

 pallid. The annexed table will aid in separating the species of 

 the genus. 



SYNOPSIS OF THE SPECIES OF PARASCOPAS. 



A. Body rather obese, the transverse sulci of the pronotum profound. 

 Lower edge and lower half of inner face of hind 

 femora blood-red obesus Gig.-Tos. 



A A. Body more elongate, the transverse sulci of the pronotum not 

 profound but still well defined. Lower edge and inner 

 face of hind femora flavous. 



b. Entire under surface of body blood-red. Cerci of male with the 

 apical two-thirds very slender, equal, directed upwards 

 and a little to the rear; supra-anal plate scarcely sul- 



cate and largely pallid sanguineus N. Sp. 



bb. Entire under side flavous. Cerci of male with the apical two- 

 thirds moderately heavy, sigmoid, flattened, the apex 

 directed to the rear; supra-anal plate largely infus- 

 cated, deeply sulcate at middle. . .chapadensis Rehn. 



Osmilia violacea (Thunherg). 



Specimens of the genus Osmilia (No. 404) are referred to 

 Thunberg's znolacca. They are typical of those with bluish 

 wings found throughout Southern Brazil, Paraguay and 

 Northern Argentina. Whether or not they are distinct from 

 the coclestis Burmeister I am not prepared to state at this time. 



Rhipipteryx brullei Serville. 



The collection at hand also contained two specimens of this 

 little gryllid. It was numbered 395. 



THE CLASSIFICATION OF THE MELOIDAE: I note that Dr. Wellman, 

 in his very interesting paper on this group, uses the subfamily name 

 Zonitinae, proposed by Ganglbaur in 1907. The name Zonitinac has 

 however been long in use for a subfamily of Mollusca, of which the 

 genus Zonites is the type. I suggest that the Coleopterous Zonitinac 

 be called Nemognathinae, with Nemognatha as the type genus. The 

 tribe Zonitini then takes the name Nemognathini, proposed in 1862 by 

 LeConte. With regard to the name of the family, T am altogether dis- 

 posed to adhere to Meloidae, which seems to be justifiable historically 

 and on the grounds of long usage. T. D. A. COCKERELL, Boulder, Colo-
