ANASTETTS. 377 



ANASTRUS. 

 Anastrus, Hiibner, Samml. ex. Schm. ii. t. 149 (1822-26) ; Wats. P. Z. S. 1893, p. 54. 



There are several groups of species all more or less allied to Anastrus, but as they 

 can be denned with considerable accuracy we think it best to treat each of them as 

 genera and to restrict Anastrus to A. obscurus, its type species, and a few others. Only 

 one of these, A. newris (Moschl.), occurs within our limits, and this is strictly con- 

 generic with A. obscurus. 



The antennae in Anastrus have a long, rather slender, gradually thickened club, 

 evenly curved, and reduced to an acute end. Palpi with the terminal joint short, blunt, 

 porrect. Primaries with a slight costal fold ; the inner margin longer than the outer, 

 the apex slightly produced ; the outer margin convex ; the cell long and rather narrow ; 

 the second median segment long and curved ; the third segment very short, about equal 

 to the lower and middle discocellulars. 



The secondaries have the anal angle slightly produced, the discocellulars and radial 

 very slender ; the third median segment very short. Hind tibiae with two pairs of 

 spurs and a long tuft from the proximal end. 



The range of this genus extends from Western Mexico to South-eastern Brazil.

Alis nigricanti-purpureis ; anticis costa ad apicem et margine externo violaceo tinctis, squamis quibusdam 

 fulvis sparsim atomatis ; posticis ad marginem externum quoque late violaceis : subtus saturate brunneis, 

 anticis fere immaculatis ad marginem externum vix pallidioribus ; posticis dimidio anali glaueo albican- 

 tibus ; palpis griseis. 



$ mari similis, sed alls magis brunneis, anticis costa ad apicem et ad marginem externum pallidioribus • 

 posticis dimidio distali pallidiore, fascia discali valde indistincta notato.

This species, which otherwise resembles A. obscurus, may at once be distinguished 

 from that species by the bluish-white anal portion of the secondaries beneath, a 

 character prominent in both sexes. 



A. newris was described by Moschler in 1878 from specimens in his collection from 

 Colombia. One of these has been lent us by Dr. Staudinger, and we are thus able to 

 name our series from Central America with certainty. In Mexico it appears to be 

 rare, though widely distributed, occurring both on the West Coast at Acapulco, at 

 Atoyac in Vera Cruz, and in Northern Yucatan, from each of which places we have
