LYCiENID.E. 115 



flattened laterally, with a dense clotliing of long stiff scales laterally 

 and inferiorly, — the terminal joint long, slender, smooth, shai'ply 

 pointed ; antennw quite slender, white-ringed, not gradually incrassated, 

 but with a distinct elongated club. 



Fore-winrjs rather variable in shape, — in the typical {Erylus) group 

 more elongate and pointed apically, — in the Faunus group more trun- 

 cate and with a more convex costa : subcostal nervure with only three 

 nervules, of which the first and second are emitted at some distance 

 apart towards the end of discoidal cell, and the third from the end 

 itself of the cell, and ending at the apex ; first radial nervule originat- 

 ing from same point as third subcostal, second from junction of curved 

 middle and lower disco-cellular nervules. Hind-ioings more or less 

 produced in the anal-angular portion, bearing a lobe at anal angle 

 itself, and a more or less developed tail at extremity of submedian 

 nervure ; almost always a second sublinear tail on first median ner- 

 vule, and sometimes a third on second median ; costa more or less 

 convex ; costal nervure terminating at apex (except in H. CccckIus, 

 Hopffer, where it ends about middle of costa) ; discoidal cell short, 

 truncate ; radial nervule originating at meeting-point of disco-cellular 

 nervules, the lower of which joins median nervure at origin of third 

 median nervule. Forc-lcgs of ^ rather long and slender, — the femur 

 hairy beneath, — the tibia scaly, with a few fine hairs, — the tarsus very 

 indistinctly articulated, finely spiny beneath, and terminating in a 

 single curved claw ; — of ^ somewhat stouter and shorter, with tarsus 

 longer and thicker, more spiny beneath, distinctly articulate, and 

 terminating in two claws. Middle and liind legs rather short, — the 

 tibia considerably shorter than the femur, and its terminal spurs long 

 and stout, — the tarsus, owing to the length of the first joint (which is 

 swollen in the hind-legs of the ^), considerably longer than the tibia. 



Larva. — Very broad and thick, slightly narrower and thinner 

 posteriorly ; head very small. 



Pupa. — Robust, rounded, rather tapering posteriorly ; head and 

 back of thorax but slightly prominent. 



(The characters of larva and pupa are from drawings by Mrs. 

 Barber of those of H. Lara (Linn.) ) 



There is considerable diversity among the butterflies of this genus, 

 as shown by the characters above given, but their slender structure 

 and only three-branched subcostal nervure of the fore-wings are 

 features which readily distinguish them from their allies the Myrince 

 and lolai. The upper surface of the males, though less metallic than 

 in the genera just named, is usually of some deep rich purplish or 

 violaceous-blue, while that of the females is dull grey or brown with 

 more or less discal white. The under surface resembles that of the 

 genus lolaus, being white or greyish with neatly-defined discal trans- 

 verse stripes, sometimes more or less broken up into separate spots.
