204 Mr. Butler's Notes on Caraina and Ti-iclietra. 



$ Bolivia; ^ Venezuela. Brit. I\Ius. 



The radiating hairs on the tegula? are -well-developod in ihis 

 species. 



•4. Carama pluinof^a, n. sp. 



Nearly allied to the preceding, but (excepting in its smaller 

 size, and the black upper surface of the anterior pair of legs) 

 agreeing with C. Wallccri. Expanse of wings $ 1 iiidi, 2 lines: 

 $ 1 inch, 5 lines. 



$ , 9 Santarem. Brit. INIus. 



0. Carama ? nivea (Cramer, Pap. Exot.), 



Siu'inam. 



This a|)p('avs to belong to the genus.

1. Trichetra sjiaishaJl! (Curtis, lirit. Ent. vii, pi. ?)'M\). 

 Australia ? 



2. Trichetra fraterna, n. sp. 



Differs fi-om T. sparshalli only in having the anterior legs 

 white, not black above. Expanse of wings $ 1 inch, 9 lines ; 

 $ 2 inches, 2 hues. 



Moreton Bay. Brit. ]\Ius. 



The female has all the wings white, the thorax black, the 

 tegulaj testaceous internally : a large sandy-brown anal woolly 

 mass. 



3. Trichetra stihosoma, n. sp. 



V 



9 Differs fi-om T. inesomelas, in having the abdomen snow- 

 white as in the preceding species, and Avith the anus tufted with 

 brown above. Expanse of wings 2 inches 2 lines. 



N. S. Wales. Brit. Mus. 



4. Trichetra mesomcla.^ (Walker, Lep. Ilet. 4, ]>. Xi't). 



$ , 9 Tasmania. Brit. Mus. 



Tlie two genera ai-e easily distinguished, Carama having a 

 radiating brush of Avhite hair on each tegula in the males, and 

 Trichetra a crest of projecting hair on the front of the head : 

 there are, moreover, other less evident chai-acters. 



* Agassiz gives this as White's genus, but he nowhere diagnoses it. 

 anil the species figured in Grey"s Australia arc not congeneric.
