Abdomen with from one to three setiferous punctures on each 

 side of the middle of the three intermediate ventral segments ; 

 last segment in the female, subacute ; in the male very 

 deeply emarginated, and with a supplementary, valvular, deeply 

 emarginated segment, the edge of which projects a little beyond 

 the preceding segment. 



Legs. Anterior tibias not notched, with a few short bristles, 

 dilated at tip, on the under side of which is a short channel 

 with its sides fringed with short hairs, and the lip armed 

 with two slender, simple spurs. Anterior tarsi in the male with 

 three dilated joints, which are covered with thick-set brushes 

 beneath, and beset with short bristles around the edges (as in 

 Chlcenius, etc.) ; first joint triangular, longer than wide ; 

 second and third nearly alike in size and form, siib-quadrate, 

 with rounded angles, more prominent within than on the out- 

 side, rather wider than the first joint ; fourth joint obconical, 

 minute ; fifth longer than the fourth, obconical ; anterior tarsi 

 of the female without dilated joints, similar to the other tarsi. 

 Intermediate and posterior legs with "a few bristles ; tibire not 

 channelled beneath the apex ; tarsi setulose and with obconical, 

 simple joints. Posterior trochanters short, oval. Nails slender, 

 simple. The few characters given by Mr. Say agree in all 

 essential particulars with the above, which contain some that he 

 did not notice. 



I consider this genus as properly placed among the Cicin- 

 delidce, for these insects differ from all the Caralndce in having 

 an articulated hook at the end of the maxillse. They should 

 come between Manticora and Megacepliala, being related to both, 

 but coincident with neither of them. Do me the favor, I beg 

 of you, to send me a transcript of the characters of the similar 

 bisect which you say Eschscholtz found at New California.
