24 AMEEICAN LEPIDOPTEEA. 



Between the segments an irregular transverse band of black markings ; subdorsally and 

 centrally on each segment a black spot, and there are three little black lines between 

 the inner and outer rows of dorsal spines. Between the lateral rows of spines is a broad 

 black band extending the entire length, and having anteriorly and posteriorly on each 

 segment a reddish spot ; this extends somewhat underneath ; otherwise underneath 

 pale green. Prolegs, abdominal and anal legs reddish. Forms an oval and thin parch- 

 ment-like cocoon on the bark of trees, usually under growing moss. 



Both in the larval and imago state this species closely resembles the moth figured 

 asjivulosa in Cramer, pi. 107 A, the larva of which is figured by Stoll, pi. 17. fig. 4, 

 and eventually they may prove to be the same species. Molippa sabina is one of the 

 commonest species in Tropical America, and in Mexico and Southern Brazil is double 

 brooded. 



I can see no reason for placing Molippa, Ormiscodes, Hylesia, Dirphia, and other 

 allied genera from Tropical America under the Lasiocampidse ; these genera are too 

 closely allied in all stages to Automeris and Hyperchiria to admit of " family " 

 separation.

Ormiscodes opts, Sehaus, Proc. Zool. Soe. Lond. 1892, p. 318. 



Primaries above reddish brown ; a basal straight, and an outer oblique, transverse 

 grey band ; a marginal wavy whitish shade ; a long white streak at the end of the cell. 

 Secondaries reddish brown ; a median transverse greyish band and a submarginal dark 

 brown shade. Underneath brown, the outer portion of the wings crossed by four bands 

 of whitish scales. Head and thorax reddish brown. Abdomen black dorsally, whitish 

 between the segments ; anal segment red ; underneath reddish brown.

Lonomia carnica, Sehaus, Proc. Zool. Soe. Lond. 1892, p. 318. 



Male. Above red, the wings crossed from the apex of the primaries to the middle of 

 the inner margin on the secondaries by a broad black line, divided by a greyish shade ; 

 on the primaries two discal spots, the anterior one blackish, the posterior one white. 

 Underneath pale brownish red, with broad marginal, paler shades ; the transverse line 

 very narrow and indistinct, inwardly shaded with white ; on the primaries two white 

 discal spots ; on the secondaries a black discal spot circled with white ; a large black 

 spot at the apex.
