182 THE CANADIAN ENTOMOLOGIST. 



to me, the genus belonging to this sub-family which I distinguish from the 

 Sarothripince ) I do not know any forms of Cochliince from California ; 

 if the sub-family is feebly represented there, it will be a fresh example of 

 the resemblance between the West Coast fauna and the European. No 

 Cuban forms were included in the collection described by me. The 

 geographical distribution of the North American Bombycidae merits atten- 

 tion. On the islands of the West Indies, there seem to be no typical 

 Spinner moths, that is to say, no Attacince, Ceratocampince, Platypterygi?ice, 

 LachneincB. In the new Check List, I included the only West Indian form 

 of this group known to me, Heuretes picticor?iis G. & R., the types of which 

 are in the Royal Museum in Berlin. Fifteen other genera are included in 

 my list, and although one or two of these are probably synonyms, not 

 being identified by me, enough is shown to prove the richness of our fauna 

 in this group. Sepp figures a South American species of Empretia. 

 The group is probably widely distributed and belongs to the older forms 

 of the family. 



Sub-family Psychince. 



The larvae of the present group are still more curious than those of the 

 Cochliince from their habit of living in a case. The thoracic feet alone are 

 developed, and the undeveloped abdominal feet present a resemblance to 

 the slug caterpillars, so that we have a reason for bringing the groups 

 together. The cocoon-making habit is not alone displayed by the mature 

 larvae, for so soon as the little Psyche larva leaves the egg it fashions a tiny 

 sack and begins its wanderings, dragging its shelter after it. In most of 

 the genera, the females are apterous and worm-like, but in the North 

 American genera with broad, falcate wings, Perophora Harris, and 

 Lacosoma Grote, the females are winged like the males. Sepp figures a 

 South American broad-winged form, and Herrick-Schaeffer, from the vena- 

 tion refers this section of the sub-family to the Attacince, notwithstanding 

 the sack-bearing larvae. The neuration will hardly guide us in this group, 

 since certain European genera have apparently three internal veins on the 

 secondaries like the Microlepidoptera. Perhaps they are wrongly reckoned 

 here. Some of the moths resemble the Dasychirince. This resemblance 

 is seen in Psyche; but the American genera Thyridopteryx and Oiketicus 

 have long-bodied males with partly glassy wings and short antennae, and 

 look more like the Cossince. As compared with Europe, we have apparently 

 very few species of Psyche; in fact only one species is well known, viz.,
