TI7////.S — (3ne marginal, appendiculate, and four submarginal cells, of 

 which the second receives two recurrent nervures. 



Aiitmuiss 13-articulate, almost moniliform, a little thicker in the mid- 

 dle than at the sides. 



1. Perreyia comptns, n. sp. 



Bhiek. with rufous abdomen and subviolaceous wings. Lengtii 0.2S. Br. 

 Avings (1.60 inch. 



%'. ]5ody stout. AntennfB black, thirteen-jointed, filiform and di- 

 minishing in thickness, joints rather cuneiibrm than moniliform, third 

 joint nearly as long as fourth and fifth ; apical joint short, obtusely 

 I'ounded ; head nearly as wide as thorax, pi)lished; nasus cmarginate, 

 scutel large, and produced behind as in Ili/Jotomn. Head, thorax, ba- 

 sal plates, and apical segment of abdomen black; abdomen yellow-red; 

 legs black, tibial spurs short, not very sharp, claws large, without in- 

 ner tooth. Wings obscure blackish, of one color; first recurrent ner- 

 vure received near base of second cell, the second in the third cell, 

 near the intersection of second and third cells ; the second a little 

 shorter than the third cell; lanceolate cell petiolate; under wings ap- 

 pendiculate, and with one middle cell. 



jMexico. Two specimens. (H. de Saussure.) 



The second recurrent nervure is received within the third submar- 

 ginal, thus differing from the diagnosis of Brulle. The antennae are 

 formed as in the figure given by Brulle of the antenna of P. hpula. 

 The submarginal bullas in this and the following species are as in Nc- 

 malns. 



2. Perreyia capitulum. 



Testaceous; head and legs black, wings obscure. 



Length % 0.28. Br. wings 0.64 inch. Length 9 0.44. Br. wings 1.04 inch. 

 9- Shining yellow-red; body stout; antenn;i3 12-jointed, formed as 

 in last species, black; head black ; a black spot on the apex of abdo- 

 men ; legs black, the coxee, trochanters and anterior femora above, yel- 

 low-red ; spurs short, obtuse; claws sinjple; wings blackish obscure; a 

 darker spot covering marginal and upper half of submarginal cells, as 

 in Iljjlotoma ; first submarginal cell oval; the second recurrent nervure 

 received at intersection of second and third submarginal cell; lanceo- 

 late cell petiolate; under wings appendiculate, and with one middle 

 cell. 



9 . The female is much larger and the wings more obscure on basal 

 half The marginal cell is obscure as in Ili/lotoma scapularis.
