GRAIS.— CEL^NOKRHINUS. 381 



GRAIS, gen. no v. 



Anastrus stigmaticus, Mab., is the type of this genus, which is distinguished from 

 Anastrus by the long narrow cell of the primaries, the absence of costal fold and tibial 

 tufts. The first median segment is short, the second long and arched, the third about 

 half the length of the second ; the lower and middle discocellulars are subequal, and 

 placed rather obliquely to the axis of the wing ; the upper discocellular is comparatively 

 long, oblique, and equal to about half the middle discocellular ; the third median 

 segment of the secondaries is long, being about equal to half the second segment ; the 

 lower discocellular is longer than the upper, and both, as well as the radial, are very 

 slender. The palpi have a very short terminal joint. The antenna? have a gradually 

 swelling club, which then tapers to a point and is evenly curved throughout its 

 length. The hind tibiae have two pairs of long spurs, but no tuft at the proximal end. 



The range of the genus is that of the single species described below.

A large dull-coloured species with very obscure markings, described by M. Mabille 

 from Chiriqui specimens, one of which is before us. 



Its range northward extends to the extreme north-eastern limit of the Neotropical 

 region in Mexico, and thence spreads southwards over the greater part of the region 

 to South Brazil and to some of the West Indian Islands. 



Antigonus fumosus, Plotz, is a synonym of this species, as we ascertain from a 

 specimen kindly given us by Herr Semper, and named from Plotz's drawings. 



The male genitalia differ considerably from those of the species of Anastrus and its 

 allies; the tegumen has a dorsal prominence before the terminal portion and ends in a 

 single blunt point; the harpes are rounded at the end, the upper corner is finely 

 serrate and emits a recurrent spur, on the dorsal edge is a distinct prominence. (See 

 Tab. LXXXIV. fig. 26.)
