CROCOTA. Hiibner. 

 Crocota Treatii. n. sp. 



Bicolorous. Anterior wings of an even dull leaden blackish color, 

 concolorons ; costal edge marked with a crimson stripe which becomes 

 obsolete towards the apex. Posterior wings crimson, no discal spot, 

 the s. c. vein marked with blackish scales ; terminal baud very wide, 

 continued, broadest at costa, resembling anterior wings in color. Under 

 surface resembling upper. Head in front blackish, behind with a crim- 

 son line which extends laterally to the bases of anterior wings : thorax 

 legs and under surface of abdomen blackish; palpi short, but slightly 

 projecting beyond the head, blackish, the basal joints clothed witli 

 crimson hairs; abdomen above crimson with a broad dorsal segmentary 

 series of black maculations. % . Exp. .90 inch. 



Habitat — Lawrence, Mass. (Coll. Mr. James 0. Treat.) 



The difficulty experienced in limiting the species of Crocota, owing 

 to their great variability, should deter entomologists from erecting new 

 species based simply upon the condition of the normal bands and spots 

 which ornament the buff, or fawn and rose-colored species, but C. Treatii 

 is not easily to be confounded with any of these than which it is more 

 brilliantly and distinctly colored and offers a structural difference in 

 the much reduced palpi compared with C. rubicundaria with which it 

 presents a similar abdominal conformation. The discovery of the pre- 

 sent species indicates the position of the genus among the Lithosiidae 

 (Lithosiina ll-S.i, where T had at first referred it in describing C. 

 optlla m.. while the Arctiid affinities of the stouter species are evident. 



I name this pretty species after Mr. James 0. Treat, whose entomo- 

 logical merits deserve acknowledgment.

 Some two years since I communicated the present species to Dr. 

 Packard, who has given a full description of this North American 

 genus and species as cited above. 



CYRTOSIA, Packard. 

 Cyrtosia ocellata. n. s. (Plate 2, fig. 2. % .) 



Anterior wings very pale brown, largely shaded at base and internal 

 margins with bright ochraceous. The two lines joining the internal 

 margin dark brown, equi distant, merged superiorly in a diffuse oblique
