$ . Head and thorax above yellowish 

 salmon color with the usual black marks ; 

 abdomen deep ocher yellow with a dorsal and 

 lateral row of confluent black spots; below, 

 the thorax, abdomen and legs are entirely 

 black. Fore wings deep black with salmon 

 colored bands, each narrowly bordered with 

 yellowish on both sides. Basal half line 

 absent, represented on one wing by a few 

 scales on the costa ; trans. -ant. line reaching 

 from costa to internal margin, rather narrow, 

 dilated at both ends; median band reaching 

 from costa to just below the longitudinal sub- 

 median band, ending in a point; trans. -post, 

 line slightly angulated, reaching only to the 

 submedian band ; terminal angular band 

 (W-mark) normal, joining the trans. -post, 

 band at about its middle; fringe and internal 

 margin narrowly salmon cclor. Hind wings 

 scarlet ("flame scarlet," Ridgwav, plate vii, 

 fig. 14) with a narrow uneven outer black 

 border, obsolete before internal angle; three 



submarginal rounded-triangular spots, the 

 last one at anal angle; two discal elongate 

 spots, the inner one much elongate and at- 

 taining the costa, the outer, small ; a large 

 spot on the middle of abdominal margin and 

 a small one at base. All the black marks 

 narrowly bordered with yellowish. Fringe 

 narrowly yellowish salmon. Below, the col- 

 ored parts of both wings are orange (Ridg- 

 way, PI. vi, f. 3) with the black parts as 

 above. Expanse 42 mm. The moth here 

 described differs from all those referred to in 

 the synonymy given above in the absence of 

 the basal half line, and I propose for it the 

 varietal name pe rpicta. 



The character, though slight, is usually of 

 such diagnostic value in the case of E. blakri 

 that its absence in this form seems to warrant 

 the different designation. Prof. French has 

 described some moths of this form as Arctia 

 geneura Strk. (Can. ent., xxi, 162). 



A Monograph of the North American 

 Tachinidae. — Prof. C. H. Tyler Townsend 

 is at present engaged on the preparation of 

 Part I of a monograph of the North American 

 Tachinidae, which he hopes to have ready 

 for publication in about two months from 

 this date. The part will embrace the Phasii- 

 dae, Gyninosomatidae, Ocypteridae, and 

 Phaniidae. Any persons having material 

 in any of these groups will confer a favor by 

 sending it to Mr. Townsend, who will return 

 it fully determined. The monograph will 

 aim to represent the entire fauna of North 

 America north of the Isthmus of Panama, 

 including the West Indian forms. Subse- 

 quent parts will follow in the course of time. 

 Mr. Townsend has been engaged on this 

 work for some years and has already a large 

 amount of material on hand, but he is de- 

 sirous of examining all possible specimens of 

 the above groups, from within the limits 

 stated, before sending the manuscript of part 

 I to the printer. 



Entomological Notes. — Miall and Ham- 

 mond have just printed a paper in the Tran- 

 sactions of the Linnean society of London 

 on the development of the head in Chirono- 

 mus, which will be found interesting from its 

 representing a type intermediate between the 

 apparently widely different types of Corethra 

 and Musca, hitherto the best known. A 

 great part of the head of the imago arises 

 from paired invaginations extending far into 

 the larval thorax. 



A feast of Chionobas is offered in the new 

 Part of Edward's Butterflies of North Amer- 

 ica, for it is devoted entirely to four species 

 of that genus, of which the transformations of 

 two, C. jutta and C. brucet, are described in 

 detail and figured profusely with exquisite 

 skill, admirably bringing out their distinctive 

 features. Considering the home of these 

 insects, one cannot too strongly commend 

 the perseverance which has culminated in 

 such a series of plates as these. The text, 

 too, is full and interesting, indicating curious
