REPORT OF THE STATE ENTOMOLOGIST I918 I95 



Adults were reared in some lo days. The larvae undergo their 

 transformations in the soil, many of them apparently emerging 

 through one hole. The insects seem to breed throughout the fall. 

 This species is best Icnown on account of its injuring the pods and 

 young twigs, though it appears capable of materially damaging the 

 foliage. The following unpublished notes kindly placed at our 

 disposal by Doctor Howard of the bureau of entomology, probably 

 refer to this species. In June 1897 Mr Pergande found on the under 

 side of catalpa leaves a number of pale greenish, whitish or yellowish 

 Itonid larvae producing a slight abrasion on the surface. Most of 

 the affected leaves showed peculiar, circular, brownish spots sur- 

 roimded by yellowish green rings. These observations were repeated 

 the following season and convinced Mr Pergande that the spots were 

 caused by the larvae. He states that the very minute eggs are 

 loosely laid upon the foliage and drop easily. They are elongate- 

 oval, pale yellowish and highly polished. The final transformations, 

 he states, must occur in the soil. 



Male. Length 1.3 mm. Antennae about twice as long as the 

 body, thickly haired, fuscous, basally fuscous yellowish; fourteen 

 segments, the fifth with stems having a length two and one-half 

 and three and one-half times their diameters; terminal segment, 

 distal enlargement cylindric, with a length five times its diameter, 

 apically a long, slender, fingerlike appendage. Palpi; the first seg- 

 ment short, stout, irregular, subquadrate, the second about as long, 

 more slender, the third one-half longer than the second, slender, 

 the fourth a little shorter than the third. Mesonotum fuscous 

 yellowish, the submedian lines yellowish; scutellum and postscu- 

 telliim yellowish; abdomen light yellow; wings hyaline, costa pale 

 yellowish; halteres yellowish. Legs a light fuscous yellowish; claws 

 long, slender, evenly curved, the pulvilli nearly as long as the claws. 

 Genitalia; basal clasp segment short, stout, roundly truncate dis- 

 tally; terminal clasp segment rather short, stout, tapering. Other 

 structures indistinct in preparation. 



Described from specimens received from Washington. Taken 

 August 16, 1880 and probably types. Cecid. ai8o4.

The pale yellowish male was reared from yellowish larvae found 

 upon the distorted, partially rolled leaves of trumpet vine, T e c o m a 

 radicans,at Albany, N. Y., in August 1905. The wing is shown 

 in plate 16, figure 5.
