the hind tibiae bearing a single terminal spur, the other tibiae without spurs; 

 tarsal claws large, thick, and strong with curved, pointed tip, thickly pectinate 

 except at the tip. 



Described from two females and one male, taken by 

 R. W. Doane, July 24, 1895, on the banks of a small 

 stream in the Santa Cruz Mountains, at Congress Springs, 

 Santa Clara County, California. In addition, the writer has 

 dissected practically adult males and females from pupal 

 cases found during February, March, and April, 1900 and 

 1901, in Los Gatos, Campbell, Stevens, Los Trancos and 

 Corta Madera creeks — all in the Santa Cruz and Santa 

 Morena mountains, within twenty miles of Stanford Uni- 

 versity, California. The writer has also taken specimens 

 in Coyote Creek, near Gilroy Hot Springs (April), in the 

 Coast Range; and G. A. Coleman collected larvae and 

 pupas in Red Cap Creek, Hoopa Indian Reservation, 

 Humboldt County, California, July 26, 1901. Named for 

 Mr. R. W. Doane. 



Immature Stages. Larvae ( PI. XX, figs. 7 and 8) rather broad and short, 

 with strongly chitinized dorsal body- wall; each segment, except the head 

 and thoracic segment with one, with two rough, black, transverse bars; 

 lateral processes rather conspicuous, double, the anterior member of each 

 pair the longer, and with hairs at its tip; tracheal tufts composed of six 

 tubules, two of which project laterally, the others anteriorly; length 7 mm. 



Pupa (PI. XXI, fig. 3) black, with narrow, high, incurving respiratory 

 plates, the two members of the pair being set widely apart; length 6 mm. 



Larvce of Two Additional Species. 



In addition to the five Blepharocerid species just 

 described, the writer has found the larvae of two additional 

 species whose pupae and adults have not yet been found. 

 As both of these larvae, one found in Colorado and one in 

 California, present external features of particular interest, 

 they are here figured and the following brief descriptions 

 of them are given, without, of course, offering names for 

 the species; it may be, indeed, and is to be hoped, that 

 the Colorado one is the larvae of Osten-Sacken's Bibio- 

 cephala grandis (described by him from Colorado), and the
