THE CANADIAN ENTOMOLOGIST. 317 



it is an open book to all, those who feel interest may peruse, those who 

 can discriminate always find the bookmark in place. For a large page 

 and bold type ivy pterisii — from Ottawa to Washington, the central plains 

 to the seaboard — that yellow, sickly, brake frond on any hillside, a 

 conspicuous feature of the landscape when attention is called to it ; date 

 July 15th. 



How clearly the light has shone over Harris's species leiicostigma by 

 reason of the food-plant being mentioned. His name fell through pre- 

 occupancy in the European fauna, but we could never have known what 

 species he meant from even the good description, had that been all. 

 Grote, at various times, placed it in the synonymy of three different 

 species and redescribed it under a fourth. That piirpiirifascia, the 

 universal Columbine feeder, was Harris's species we know beyond 

 question, since that good man mentioned that its larva had feasted on 

 the roots of a fine double Columbine in his garden. His description of 

 one hundred and twenty words might have been cut in twain ; his type — 

 it has probably gone where all good types will ultimately go. Life- 

 histories were generally unknown in Grote's time, and though now slowly 

 giving up their secrets, there is great need for co-operation, especially 

 from the West. 



NEW TROPICAL AMERICAN HESPERID.E. 



BY GEO. k. EHRMANN, PITTSBURGH, PENNA. 



Leucochitonea Jason, n. sp. — This species is very closely allied to 

 L. lociitia of Hew., but it is not so robust in build. The colour of the 

 head, thorax and abdomen is paler. Ground colour of the upper side 

 of both pair of wings has a tendency to being semitransparent ; basal 

 area is not so dark. Outer margin is lightly shaded with pale brown ; 

 in this shaded space on the hind wings is a marginal row of whitish 

 lunate spots. Fringes on the hind wings are white, on the fore wings 

 black. 



Under side : palpi, legs and abdomen white ; thorax dark brown. 

 The markings on the underside of all the wings are the same as above, but 

 much paler. I find no special distinction in the markings in the sexes for 

 separate description. 



Exp. 2 inches. Types in cabinet of Ehrmann. Hab. : Suapure, 

 Venezuela.
