a judgment can onl}' be given by one wbo has mastered the Ilcspcridse of the 

 whole world and not a mere fragment of them only. At the end of them 

 is to be placed Euschemon at all events, which makes the transition to the 

 Heterocera. — S. 



€ARTEROCEl»HAL,US, Led. 



TibiiB without tibial epiphysis; those of the hind legs without middle 

 spurs; knob of autennse elongate-ovoid; tip blunt, conical; last joint of palpi 

 concealed by the long bristles of the middle joint; abdomen extending beyond 

 the anal angle of hind wings. 



Note. — The tibial epij^hy sis I call the mostly flat spine or lancet-shaped append- 

 age on the inner side of the tibia of the fore leg, possessed by most of the Hetero- 

 cera, but among the Rhopalocera by the Papilionidse and Hesperidje only. In 

 the latter this appendage is externally covered with scales, interiorly and at the 

 apex naked, and not reaching the end of the tibiae. — S. 



AXCYEOXYPHA, Feld. 



Tibise with tibial epiphysis; those of the hind legs with middle spurs, (as in 

 all the following genera). Similar to the foregoing genus; knob of antenna 

 elongate-ovoid, rounded at tip, with a very short,. slender spine attached to the 

 last joint; last joint of j^alpi free, long, perpendicularly erected, slender, siibu- 

 late; abdomen of male slender, twice as long as head and thorax; fore wings 

 elongated, blunt; hind wings rounded, the costal margin long, surpassing the 

 inner angle of fore wings; the inner margin short, not produced at the anal 

 angle. 



COP.'EODES, Speyer. 



Antennae sliort, one-third as long as the triangular fore wings, at three-fifths 

 of their length suddenly inflated to an ovoid knob, widely rounded in front, 

 sub-truncate; last joint of palpi nearly free, perpendicular, a little recurved, 

 subulate; hairs of the brush at base of anteunse dilated at tip; femora thinly 

 viDose ; tibise nearly naked, those of middle legs with a pair of very short, fine 

 spurs; abdomen glossy-scaled, hairless ; the male with a fine black longitudinal 

 stigma on tlie disc, which forms on the under side a prominent ridge, but is 

 there covered with scales. 



Note. — As much as I dislike the multiplication of genera, still less the separation 

 of sinlge species, I feel myself compelled by the striking difference of character 

 between a whole series of organs to separate generically Procris and Tliymelicus. 

 I hope that the diagnosis of the new genus will justify the separation. The 

 scaly hairs at the base of antennae would not justify the creation of a new 

 genus; they seem also to exist in some species of other genera between the 

 common hairs of the brush. — S. 



TIIYMEI.ICU.S, Speyer. 

 Antennae half as long as fore wings; at three-fifths of their length gradually 

 inflated to an elongate-ovoid knob; tip conical, blunt; last joint of palpi con-
