secondaries there are two internal or free veins, not forked at 

 base; veins 3, 4 and 5, in both wings, are rather close together, 

 5 not nearly approaching the middle line between 4 and 6. In 

 all the specimens examined by me, there is a distinct accessory 

 cell in the primaries. In the genus Orgyia the female is wingless, 

 with feebly developed head and thorax, but enormously distended 

 abdomen. She never moves from the cocoon inclosing the pupa 

 from which she has emerged, and the eggs are laid in a white 

 mass on its surface. In the other American genera the females 

 have developed wings and are larger than the males. The cater- 

 pillar of O. Icucostigma, distressingly common in many eastern 

 cities, will serve as a fair type of the larva of this family, exclud- 

 ing, as before, Lagoa and its more immediate allies. 



In Lagoa, for which Dr. Packard has suggested the term La- 

 goidce, we have, as has been indicated, an approach to the Li- 

 macodid, or more typical Bombyx type, whereas Orgyia ap- 

 proaches the Noctuidse very closely indeed so closely that it 

 would be almost impossible to distinguish some broad winged 

 noctuids by venation alone. Lagoa has a much heavier body 

 with comparatively smaller wings than Orgyia; the vestiture is 

 more loose and divergent, and the species have a "fluffy" ap- 

 pearance. In the female there is a massive tuft of scaly hair at 

 the tip of the abdomen, giving it a swollen, obtuse appearance. 

 The primaries have one simple internal vein; 4 and 5 are rather 

 close together from the end of the median vein, and 6 is from the 

 middle of the cross-vein closing the cell. Numbers 7, 8 and 9 

 are from a single stalk arising with 10 from the end of the sub- 

 costal. The cross-vein closing the cell is inwardly angulated arid 

 sends in through it a very distinct fold, feebly dividing the cell. 

 The secondaries have two free internal veins; 4, 5, 6 and 7 are 

 from the end of the median cell, 4 and 7 at the lower and upper 

 angles; while 5 and 6 are from the cross-vein at nearly equal dis- 

 tances from each other and from 4 and 7 respectively. From 

 the middle of the cross- vein, a very distinct fold, rising to the 

 dignity of a feeble vein, runs inwardly, dividing the median cell. 

 There is no free costal vein, but just before the end of the cell 

 the subcostal sends off a branch vein 8 to the outer margin 

 before the apex. 



The Limacodidae are moderate or small-sized forms, with 

 usually rather plump bodies, retracted head, obsolete tongue and
