Loxostege coloradensis G. & R. (det. McDunnough) was bred at Boulder, Sept. 12, 

 from a larva folding leaves of H. annuus. The larva is very pale yellowish, with a 

 narrow greenish-grey dorsal band and a broad dilute grey band on each side; the 

 tubercles are conspicuous and jet-black, each with one long hair. Head clear pale 

 reddish.

Asphondylia websteri n. sp. The occurrence of a European species in an isolated 

 area in the southwestern United States appeared remarkable, though prior to the 

 rearing of a large series of this fly by Mr V. L. Wildermuth at Terape, Arizona, in 

 1917 it was impossible to more than question the earUer identification of this insect 

 as the European A. miki Wachtl. The American form is a decided^ smaller, darker 

 and more naked species. The general characteristics of the insect have been admir- 

 ably given in the below cited circular by Professor Webster, to whom we take pleasure 

 in dedicating this species. 



Male: Length 2.25 mm. Antennae nearly as long as the body, practically naked, 

 dark brown; 14 segments, the fourth cyhndric, with a length about six times its 

 diameter and moderately stout, low circumfih. Palpi; first segment short, subquad- 

 rate, the second with a length over four times its diameter, the third a little shorter 

 than the second, narrowly oval. Eyes large, black. Mesonotum dark reddish 

 brown, practically naked, there being only a few short, sparse, yellowish scales and 

 no well marked submedian lines. Scutellum reddish bro\\Ti, postscutellum yellowish 

 brown. Abdomen mostly a dark slaty browTi, the genitalia reddish brown. Wings 

 hyahne, almost naked, costa a light strawy brown. Halteres mostly pale yellowish, 

 slightly fuscous subapically. Coxae dark reddish brown. Femora, tibiae and tarsi 

 mostly a pale yellowish brown, the tarsi slightly darker. Genitalia; basal clasp seg- 

 ment short, stout, terminal clasp segment very short, stout, irregularly and strongly 

 bidentate. Dorsal plate long, broad, broadly and triangularly emarginate, the 

 divergent lobes narrowly rounded. Ventral plate shorter, deeply and roundly emargi- 

 nate, the short heavy lobes obUquely truncate. Style moderately long, stout, nar- 

 rowly round apically. 



Female: Length 2.25 mm. Antennae about | the length of the body, practically 

 naked, dark brown, the fourth segment with a length about six times its diameter, 

 the fifth with a length about five times its diameter, the twelfth and thirteenth seg- 

 ments each with a length about equal the diameter, the fourteenth reduced, cuboidal. 

 Palpi; first segment short, quadrate, the second with a length fully twice its diameter, 

 the third about tTvace the length of the second, more slender. Mesonotum shining 

 dark brown with a very few short, yellowish hairs. Scutellum yellowish, post- 

 scutellum yellowish orange. Abdomen a shining dark brown, reddish brown apically. 

 Coxae dark brown, legs mostly a strawy bro'mi. Claws rather long, somewhat slender, 

 the pul villi shorter than the claws. Ovipositor when extended nearly as long as the 

 thorax and abdomen. The dorsal lobes well developed. Other characteristics 

 practically as in the male. Type Cecid. a2420.
