The other species of Heterocampa included in Prof. Smith's 

 list are unknown to me. They are Chapmani Grt., superba Hy. 

 Edw.. thyaiiroides Walk., mollis Walk, and nigrosignata Walk. 

 H. nigroscripta Walk, is said by Mr. Kirby to be Thiacidas 

 postica from India, hence wrongly included in the list, and, finally, 

 H. nivea Neum. is a Cerura, and has been redescribed by myself 

 as C. nieridionalis (Psyche, vi, 291). 



Arctia minea Slosson. 



I have examined the types in the collection of Mrs. Slosson. 

 They are normally marked A. michabo Grt., but differ in the red, 

 fiery tint of the pale marks which, in viichabo, are usually of a 

 pink tint. The name is probably worthy of varietal rank. 



Cernridia Slossonii Packard. 



I am also indebted to Mrs. Slosson for the opportunity to ex- 

 amine this curious form. It is, with only slight doubt, a female 

 of Gluphisia avimaaila Hudson, of which the yellow shades are 

 replaced by black. This variation is common in the genus; I 

 ha\e seen it in G. severa and the common G. irilineata, though 

 these forms have not received names. The generic name Ceru- 

 ridia is the same as Melia Neum. if my determination of the 

 moth is correct. Both names appear to me unwarranted, as the 

 moths do not differ in structure from Gluphisia, and the larvae 

 are identical in form and in pattern of markings. The species 

 are somewhat larger than Gluphisia proper, but the pectinations 

 of the S antennae are no longer in proportion. The species to 

 which the names are applicable are: 



6 Llntneri Grote. 

 6. severa Hy. Edw. 



Danhyi Xeum. (type of Melia). 

 O. avimacala Hudson. 



Slossonii Packard (type of Cernridia) . 



The Bombycidae of Prof. Smith's list are a very heterogeneous 

 assemblage. The genera Pseudohazis and Hemileura undoubt- 

 ■edly belong to the Saturniidae. This family has been too closely 

 restricted by Prof. Smith. The females of some of the species 

 which he has included .show gradations to the simply bipeciinate 

 antennae, as do some of the moths in having the two sets of pec- 

 tinations of unequal length, and it is but a natural step to Psen- 

 dohazis and Hemileuca, which are otherwise the same in the 

 structure and in the larva. They are totally dissimilar to the 

 other species, which are all true Lasiocampidae, with the possible 

 exception of Thauma ribis, which I have not examined. Quad-
