infuscated, but is otherwise like suhimmaculata, and seems to be 

 merely an anomalous specimen of the latter species. 



There is a rather pronounced variation in size among the series 

 described below, and the vestiture of the submarginal vein varies 

 numerically somewhat with the size of the specimen, as has been 

 noted in other instances within the genus. 



The collection of the United States National Museum contains a 

 series (3767 and 3767'') of 17 females and 10 males, all representing 

 the smaller sizes of this species, reared by Albert Koebele from the 

 twig galls of Heteroecus pacificus (Ashmead). Koebele reported it 

 from Quei'cus puinila^ but Doctor Kinsej^ informs me that Q. chryso- 

 lepis is the only known host of H. paci-ficus and that Q. pumila is a 

 species of Southeastern United States. The specimens bear dates as 

 follows: September 24 and October 2, 1885, and January 21, 1886. 

 Most of them are not dated. The galls were collected September 9, 

 1885, at Colfax, Calif. In the same collection is one female reared 

 at Cottonwood, Calif., January 19, and a small, darker male dated 

 February 11, both from a gall on Q. lohata. It is probable that 

 these are conspecific despite their differences in color. 



Eight males and females, with record numbers 3794a'', 3794a''^, 

 3795"^, and 3797^^, were reared by Mr. Koebele at Colfax, Placer 

 County, Calif. The one specimen from 3797'' was reared January 

 8, 1886, and the gall received, presumably at Washington, D. C, on 

 October 17, 1885. This female was reported by Koebele from the 

 gall of Heteroecus dasydactyli (Ashmead). Kinsey ^° indicates that 

 Ashmead had mixed galls, which probably represented two species, 

 H. dasydactyJi and H. vielanoderma Kinsey. Hence, the exact cyni- 

 pid host for this lot is in question. 



The specimens numbered 3794a'', and presumably those bearing 

 other combinations of 3794 and 3795, came from an unidentified gall 

 collected by Mr. Koebele at Colfax, Calif., from Q. chrysolepis and 

 were received at Washington, D. C, on October 17, 1885. One rear- 

 ing record is January 20, 1886 (3794"). It is highly probable that 

 the maker of these unidentified galls was also a species of Heteroecus. 



Two specimens (59°) from Placer County, Calif., probably issued 

 January 2, 1886, from a cynipid gall collected October 8, 1885, on 

 Q. chrysolepis. Joseph Wade furnished me these data, which accom- 

 pan}^ record number 59'', and probably refer also to this series. 

 Mr. Koebele was perhaps the collector. 



In addition I have a series of 10 specimens reared by Dr. A. C. 

 Kinsey from California cynipid galls on Q. chrysolepis as follows: 

 El Portal; San Jacinto Mountains, Andricus spectdbilis Kinsey; 

 Placer ville and El Portal, Heteroeam padficus pacifiem (Ashmead) ;
