ACHLYODES. EUSCHEMON. HESPERIA. 



Genus XII. EUSCHEMON. 



EuscHEMON E. Doubleday. 

 Hesperia Mac Leay. 



Body robust ; wings large, black, with sulphur coloured markings. 



Labial Palpi rather small, broad, scarcely projecting beyond the front hairs of the face. Terminal joint very 



minute, sub-horizontal. 

 Antennce long, thickened beyond the middle into a rather thick fusiform club, and terminated by a long reflexed 



slender point. 

 Fore Wings large. Costal margin nearly straight. Apical angle rounded ; apical margin convex. Veins 



arranged as in Pamphila; the disco-cellular veins being transverse. 

 Hind Wings broad, subtriangularly rounded, the base furnished with a bristle (in the males only ?), which passes 



through a ring attached to the under side of the postcostal vein of the fore Avings, near the base. Discoidal 



cell considerably elongated, terminated by a transverse very slender disco-cellular vein. 



The type of this genus is a fine Australian insect, which Mr. E. Doubleday regarded as not belonging to the Diurnal Lepidoptera, 

 on account of the possession of the " spring and socket," which is so characteristic of many of the moths. It is indeed true that we 

 know no other Diurnal Lepidopterous insect with tliis structure, but the veins of the wings are identical with those of the majority of 

 the species of this family, the antennas also exhibiting a similar resemblance, so that I have no hesitation in considering it as a butterfly 

 belonging to the present family.

Genus XIII. HESPERIA. 



Hesperia Fabriciu.9, Swaim^on {Z0OI. III. 1st ser.). 



General characters of Pamphila. 

 Head broad, body robust. 



Labial Palpi compressed in front, and incurved, witli the sides convex or angulated ; the last joint minute, 

 horizontal. 



Anten7ia3 of moderate length, or elongated, straight, slender, with a sub-terminal club, variable in length and 

 thickness, but hooked at the tip. 



Fore Wings elongated-triangular. Apical margin more or less convex. The costal margin not reflexed, and the 

 disc in the males not marked with the oblique silky patch; often marked with pellucid spots. 



Hind Wings subtriangular, with the anal and outer angles rounded, or with the outer margin rounded and some- 

 times dentated. The anal angle not produced into a prominent lobe or short tail, and the disc beneath not 

 marked with silvery spots.
