Description : Length — 2.5 mm. Color — Brownish yellow with 

 median and transverse dark bands, dark spot on head and 

 thorax II, and distal end of each segment of the antenna 

 purplish. Antennae — Little longer than the head; I shortest, 

 III longer than II, and IV longer than III and twice as long as 

 II. Ocelli — Sixteen. Postantennal organ — Oval. Claws — Two ; 

 su])erior, stout, tapering but slightly; no teeth on inner margin 

 l)ut on second and third pair of legs there is a minute tooth; 

 inferior, short, about one-half length of superior, dilated at 

 base, armed with a minute tooth on inner edge ; no tenent hairs 

 present. Furcula — Does not quite reach ventral tube; dentes 

 nearly three times as long as manubrium; mucrones four- 

 toothed, first is minute and at the base of the second, second 

 and third subequal, fourth arising from the side and extending 

 eaudalward, reaching beyond the base of the third tooth. 

 Integument — Body set thickly with short, stout brown hairs of 

 about an uniform length. 



Variation: Mine differ from Guthrie's in that there is no 

 green on the legs, ventral tube or furcula. In Guthrie's speci- 

 mens antenna IV is more slender than III and seldom quite as 

 long, in mine it is longer. 



Habitat: Camp Baldy, altitude 4700 feet, January. Slippery 

 Elm Eidge on slopes of Mt. San Antonio, altitude 7000 feet, 

 December. This species has been reported from Europe, Asia, 

 Africa and North America. Guthrie found them "on the 

 surface of stagnant water, and on leaves and rubbish along the 

 edge of lakes and streams during the whole summer; and in 

 winter as well, when one can find a place where the snow is 

 sufficiently inelted to allow access to their haimts." 



Genus Drepa)inra, Schott 



I have found but one species of this genus. 

 This is essentially an Entomobryan with but one hook on 

 the mucrones. The fourth segment of the abdomen is from
