THE SPECIES OF CALYPTOCOME WARREN 



{Lepidoptera, Geometridai) 

 By HARRISON G. DYAR 



The genus Calyptocome was founded by Warren (Nov. Zool., vii, 

 1 48, 1 900) for pannaria Guenee as type. A considerable material is 

 before me of species allied to pannaria, amassed by Mr. Wm. Schaus in 

 his collection, now in the National Museum. It seems worth while to 

 sort them out, as they are somewhat confused. Mr. Schaus has identi- 

 fied the material, especially that recently collected by himself in Costa 

 Rica, and with the assistance of Mr. Wm. Warren in regard to the ma- 

 terial in the older part of the collection. In spite of Mr. Schaus's usual 

 care and conscientious comparisons a number of errors have crept in, and 

 some species have been united which appear to me distinct. The stand- 

 ing of the genus Calyptocome will, no doubt, be made clear by Prout in 

 his treatment of the Acidaliinae now in the press of the Genera Insec- 

 torum ; but it is not probable that he will especially differentiate the spe- 

 cies here mentioned, on account of the object and scope of the Genera 

 Insectorum. I have used Calyptocome here for the species allied to pan- 

 naria only, and have stopped including species whose general appearance 

 became too diverse, even where the general structure has not changed. 



Of the species occurring in the United States, pannaria is found in 

 our fauna as far north as North Carolina, and is recorded from New Jer- 

 sey (Smith's Rept. Ins. N. J., 1 909, p. 498), evidently having reached 

 us by way of the mainland. Another species, purpurascens Hulst, occurs 

 in southern Florida, derived from the Antillean fauna ; a third from Flor- 

 ida, rubrotincta Hulst, may be a suffused form of purpurascens. A
