118 CVXIPIDOrS GALLS AXD (i ALL-WASPS— ASHME AD. 



Sometimes tliree or more of these galls occur close together on the 

 branch, and with their woolly covering present a curious appearance. 

 Cue specimen in the collection is almost globular, but all the others 

 are as described above. 



GaUJiij. — Female. Length, ,'i.S mm. Clear reddish brown; vertex 

 of head and the extreme tip of abdomen dusky; antenna' and legs 

 brownisli yellow. 



Head and thorax minutely, finely punctate, the pleura with fine 

 stria*. Antenna' 1 l-jointed, ratlicr long, the third joint one-third longer 

 than fourth, the following to eighth gradually shortening, beyond 

 this about equal, the terminal joint being slightly lengthened. The 

 parapsi<lal grooves are only distinct on the i>osterior half of the meso- 

 notiim, entirely wanting anteriorly; anteriorly extending to about the 

 middle of the mesonotuni are two median, glabrous lines; posteriorly 

 there is a long median grooved line, while the line on the shoulders is 

 distinct; the scutellum is more coarsely rugose at the apex, the basal 

 fovcic large, ovate. obli(pie, approximate, glabrous at bottom. The 

 abdomen is slightly longer than the head and thorax together and of 

 the usual shape. Wings glassy hyaline, only slightly pubescent, the 

 veins i)ale yellowish, except the basal nervuie and the vein at base 

 of marginal cell, which are brown; this last vein is arcuate but not 

 angulate. The areolet is large and the cubital cell is not (piite closed.

J>escribed from many female s]>cciuu'ns, which issued at various dates 

 betwe n January 18, 1885, and I'ebruary 11, 1880. The gall occurs in 

 California on Qiicr<-u.s cJiri/solcpis.! and was sent to the Department of 

 Agriculture by Mr. Albert Koebele. 



9. ANDRICUS PACIFICUS, new species. 



Gall. — An irregular, globular gall, almost rouiul, or then with the 

 apex acuminate and the base, or where the gall is attached to the twig, 

 narrowed and elongated. It is of a light brownish-yellow color, smooth, 

 and, in two or three specimens, slightly polished; internally it is of a 

 hard, pithy structure with a distinct, large larval cell; diameter vari- 

 able, from <! to 10 mm. The great variation in size may be occasioned 

 by the smaller .ones being deformed or parasitized si)ecimens. 



GaUfly. — Female. In stature, color, and markings this species can 

 not be separated from A. (h(si/(la«-ti/Ii, yet the gall produced by it is 

 entirely different, and it must necessarily be distinct, but alter I he 

 closest study I am unable to seize a single character that will se])araf e 

 the flies, and the gall must be relied upon to separate the two si>eeies.
