Three specimens (two males one female) are before me. The an- 
tenme iu the male are very feebly serrate, the wings are narrower 
ami longer than usual, and the nearest ally is 
I notice that, by some accident, group palilis is omitted in my 
Revision of Tteniocampa, though the characters of the group are 
given. 
One pair is in the coll. U. S. Nat. Museum ; others are in Mr. 
Bruce’s hands. 
Tieiiioeampa pectiiiata Smith. 
When I described this species, from scant material, there was a 
rubbed and faded male s])ecimen in the coll. U. S. Nat. Mus., which 
I identified with this form, and from which the figure of the sexual 
characters was made. Since that time new material has been re- 
ceived, and I have described the genus Perigonica, to which I find, 
on renewed study, the supposed T. pectlnata belongs. A number of 
fresh, clean specimens of the latter enable me to give a correct figure 
of the sexual characters, and for comparison I add the figures of 
Perigonica angulata and P. falminans, all from typical specimens.

This genus, among others, was monographed, our American species 
alone considered, in the Proc. U. S. Nat. Museum xii, 490, and I 
there called attention to the fact that our species did not in all re- 
spects agree with the European tyjies. I have since received a speci- 
men which fills all the requirements of the generic description, and 
i\Ir. Edwards’ genus Strefchia, which antedates iMr Orote’s name
