dominal segments, as compared with the ihud, vaiic^ grcally accuidiiig lo 

 the amount of contracting in drying ; when fully extended they together 

 are much longer than the third ; finally, the eyes in death are almost black. 

 The proboscis varies in length from three to four and a-third times the 

 length of the head. The sexes are essentially alike, both in colouring and 

 in structure, with the exception, of course, of the sexual organs. The 

 species will be readily recognized by the deep orange-yellow ground colour 

 of the abdomen. 



In both of the above species the palpi are cylindrical and reach half- 

 way to the anterior oral margin, and the anal cell is closed And short 

 petiolate. 



My collection contains a single female specimen which in structure 

 is identical with the above two species, except that the anal cell is wide 

 open. A character so important as this necessitates the erection of a new 

 genus, for which I propose the name of Apomidas, n. gen. As it is identi- 

 cal with Rhaphiomidas, except in having the anal cell wide open, no 

 further characterizing of it will be required, and the species is as follows : — 

 Apomidas trochilus, n. sp., ? . 



Head, including the antennae and palpi, reddish-yellow, occiput and 

 proboscis black, the latter being three times as long as the head ; pile of 

 head white. Dorsum of thorax black, the four corners, hind margin and 

 pleura, including the cone, reddish, the breast largely black ; pile and 

 bristles of thorax white. Scutellum reddish, the pile and bristles white. 

 Abdomen and venter reddish and yellow, the pile white, that on the 

 last three segments black and directed forward ; circlet of twenty-four 

 spines of last segment black. Legs reddish-yellow, the spines yellow, a 

 few on the hind legs black. Wings hyaline, showing a faint milky tinge 

 in certain lights, veins yellowish. Length, 33 m m. Merced Co., Cal. 

 A single female, in midsummer. 



CORRESPONDENCE. 



MEETING OF THE ENTOMOLOGICAL CLUB. 



Sir, — The Secretary's report of my remarks in the discussions held at 

 the meetings of the Entomological Club at Rochester, as published in the 

 October issue, is certainly better than such reports usually are when not 

 revised by the author. The language, however, is hardly my own, and 

 in some cases the expression is misleading. I would therefore beg space 

 for the following emendations : —
