species. The identification and synonymy of all the North American 

 MaUotae, including even po!<ticata and Burda, require a revision. 



240. Criorrbina armillata Sacken, Buff. Bulletin, 1. c. $. 



Black, thorax hronze color, with fulvous \n\e; face, antennae, tip of 

 femora, tibiae and three basal joints of tarsi, yellow; tibiae with a black 

 ring in the middle. Length: ll — 12 mm. 



Fare and front above the antennae honey- yellow; upper part of 

 front and vertex blackish- bronze color, with fulvous pile; a black spot 

 on the cheeks; antennae yellow - ferruginous , arista black. Thoracic 

 dorsum and scutellum greenish- bronze color, clothed with erect fulvous 

 pile; pleurae and pectus black. Abdomen black, shining, clothed with 

 black pile; a tuft of yellow pile on each side at the base. Halteres 

 yellow. Coxae and about two -thirds of the femora black; the end of 

 the latter, the tibiae, except a black ring in the middle of each, and 

 the three basal joints of the tarsi are of a saturate yellow; the two last 

 tarsal joints black. The proximal two -thirds of the wings are tinged 

 with yellowish, the remainder is gray; the latter coloring extends along 

 the posterior margin as far as the axillary excision; within the yellow 

 portion, there is a hyaline spot in the angle between the first and se- 

 cond veins (at the i^roximal end of the marginal cell); the veins near 

 the root of the wings are all tinged with yellow. 



Habitat. Quebec (Mr. Belanger). A single female specimen. 



2-11. Crioprora, nov. gen. In a note to his description of Brachy- 

 palpus Cj/ajiorjai^ter , Mr. Loew observes, that this species holds the 

 middle between Brachi/palpuf^ and Criorrhina. that it has a remarkably 

 projecting face and would deserve the establishment of a new genus. 

 Since the publication of my Western Diptera, I have seen Dr. Loew's 

 type of B. cyioiogitster and have perceived at once that it belongs to 

 the same group with my Pocota cyancUa and P. aJoptx from California, 

 which I had doubtfully referred to St. Fargeau's genus Pocota (Western 

 Diptera, p. 339). At the same time, I have also seen the european 

 Pocota opifonnift, the typo of the genus, and have become aware that 

 my two californian species, as well as B. cyauogaster, cannot be referred 

 to Pocota. For this natural group of three species, I form therefore a 

 new genus, and propose for it the name of Crioprora (xoi,o7T()i/it)og, with 

 the face of a ram). The new group is characterized by the structure 

 of its face, which forms a short snout, prolonged anteriorly, rather than 

 downward, without tubercle in the middle and with an emargination at 

 the tip; in the profile, the face is gently concave between the antennae 

 and the oral edge. 



Pocota is called by Schiner PJocota St. Fargeau; the latter author 

 however calls the genus Pocota, probably from IJoxog sheepwool, and 

 jroxooj, to cover with wool. Since I made this correction in my Western 

 Diptera, p. 339, Mr. Verrall has drawn my attention to the fact, that in 

 ^Valker's Ins. Brit. Dipt I, 2;]8. as well as in the Index, in Vol. Ill, 

 the genus is correctly called Pocota. 



242. Milesia Amithaon Walker, which I saw in the Brit Mus., looks 

 very much like a Brachypalpus.
