OSTEN SACKEN ON WESTERN DIPTERA. 205 



Belongs to my subgenus Arrlienica (Monogr., iv, p. 252), aud is 

 closely allied to my E. siyinosa from New England. 



In my Monograph, I omitted to mention that Megistocera chilensis 

 Philippi from Chili is very probably not a Megistocera at all, but an 

 Erioeera with long antennae. This is the only South American species 

 with long antenuDB which I know of as yet, and the circumstance that 

 it belongs to Chili is in keeping with certain other analogies alreadj^ 

 noticed between the Chilian and the Californian fauna. 



Erioceea brachycera n. sp., S 9 . — Antennae short in both sexes ; 

 five posterior cells; thorax brownish-yellow, with four brown stripes; 

 abdomen brown. Length, male, 14™™; female, with ovipositor, 22™™. 

 Antennae of the male about as long as head and thorax together ; basal 

 joints reddish, the remainder brown; the first joint of the flagellum is 

 the longest; the three following but little shorter; the end of the last 

 has the appearance of bearing a seventh minute joint ; antennae of the 

 female shorter than those of the male; the first joint of the flagellum 

 is the longest; the following joints gradually decrease in length and be- 

 come indistinct; frontal tubercle brownish above, yellowish in front; it 

 bears a tuft of blackish hair. Thorax brownish-yellow, sometimes more 

 grayish above, with four brown stripes ; pleurae brown, with a hoary 

 bloom, which extends over the coxae. Abdomen brown, but little hairy; 

 valves of the ovipositor but very little curved, long and narrow, ending 

 in a blunt point; halteres reddish, with a brown knob; legs brown ; 

 base of femora reddish. Wings strongly tinged with brown ; stigma 

 brown, oval ; five posterior cells, the second on a long petiole. 



Hab. — White Mountains (H. K. Morrison). Two males and a female. 



I find now that what I described in the Monogr., iv, p. 253, as the 

 female of Eriocera sjfuiosa is the female of the present species. 



Section VI. — Amalopina. 



Amalopis calcar Osten Sacken, Monogr., iv, p. 2GS. — A single male, 

 from Webber Lake, Sierra County, July 25, does not show any percepti- 

 ble difference from the eastern specimens, except that it is somewhat 

 paler in coloring; the male forceps is yellowish and not brownish ; the 

 venation is exactly like tab. ii, f. 14, except that both the second sub- 

 marginal and second fiosterior cells are petiolate and not subsessile 

 (the same is the case with most specimens of A. calcar ; the one whose 

 wing is figured happened to be somewhat abnormal). 



Amalopis n. sp. — Que female specimen from Craftou, near San Ber- 

 nardino, Cal., in March. Body brownish ; wing immaculate; venation 

 like 1. c, tab. ii, f. 14, except that the praefurca is a little shorter, the 

 second posterior cell petiolate. I do not name it, as I have only a single 

 damaged specimen. 



Pedicia obtusa u. sp. — I have seen a single specimen of this species 

 in Mr. Henry Edwards's collection in San Francisco. It was taken near 

 Saucelito, Marin County, Cal., in the spring. Xot having the specimen
