GENUS EDWARDSIMEMNA N. & D. (Type jalapae Edw.) 



Edwardsimeinim Xeumoegen & Dyar. Jour. N. Y. Ent. Soc. II, 152 (1894). 



Eyes naked, rather small ; palpi projecting beyond front, porrect ; antennae 

 bipectinate ; abdomen not exceeding hind-wings ; primaries with very small 

 cell, discal bar crossing between veins Ri and R=, causing Rj, R,-, and Mi to appear 

 stalked ; R2 and Rs on long stalk, R: to apex, Ra to outer margin. Secondaries 

 with Mg and Ma from a point at lower angle of cell ; intercostal cell small ; 

 margin of wing undulate. 



Judging from the single $ specimen before us the genus is a good 

 one. The naked eyes and short cell of primaries are distinguishing 

 features.

Gloveria jalal'ae Edwards, Papilio IV, log (1884) ; Druce, Biol. Cent. Am. Het. 

 I, 202 (1887) ; id, II, 428 (1897). 



One of the smallest species of the group and easily recognizable. 

 It has a marked resemblance to small D. pini from Europe. 

 Habitat : — Mexico, Jalapa. 



GENUS DICOGASTER n. gen. (Type coronada Barnes) 



Eyes very large, prominent, naked ; antennae of 5 with long pectinations, 

 of 5 with short thick ones ; palpi stout, porrect, extending beyond front ; epi- 

 physis in $ well developed, in 9 lacking ; abdomen of $ with broad anal tuft, 

 projecting slightly beyond wings; shape of wings much as in Quadrina, outer 

 margin entire ; venation of primaries as in Quadrina, except that vein R: term- 

 inates at apex and Rj at outer margin; traces of ist anal wanting; secondaries 

 with intercostal cell comparatively small ; M: and Ma slightly stalked ; Cui 

 from around lower angle of cell. 



The large naked eyes are characteristic of the genus. In a series 

 oi 20 S S and 7 ? 9 of coronada examined, no trace of hair could be 

 discovered. In general the venation is very similar to both Quadrina 

 and Prorifrons; the beak-like prominence of this latter genus is, how- 

 ever, not so marked in Dicogastcr.

 Gloveria coronada Barnes, Can. Ent. XXXVI, 268 (1904). 

 Gloveria valens Dyar, Bull. Brook. Inst. Mus. I, (7) 185 (1905)- 



A very variable species, variation well illustrated by a series of 

 20 ^ 5 and 7 5 9 in Dr. Barnes collection, mostly bred specimens.
