Accordingly, Dibrachys. Fig. 8.—Dibrachys boucheamu, female be obtained in abundance year after year, without noticeable periodic recessions. It has proved to be one of the three mosl serious para- sites of A. melanoscelm. xVlthough of small size, it appears to be very hardy. In the lab- oratory specimens have been kept alive for two or three months. Despite its small size, and contrary to Tothill's assumption {36 . it is a prolific species, ruder laboratory conditions four females depos- ited, respectively, 235, 255, 375, and 389 eggs over a period of approx- imately two months. The largest number laid on any one day by a single female was 29. It is likely that under natural condition- even more eggs may be deposited. Unfertilized female- oviposil as readily as those that have mated, but the result of such reproduction is always males. Nearly always several eggs are placed in the same host cocoon, and as many as 14 individuals have been found to mature upon a single Apanteles, the species being normally gregarious in the larval stage. Females have not been observed to deposit more than three eggs at one insertion of the o\ ipositor, but the same cocoon is usually attacked more than once. There is much variation in the size of the adults in consequence of the varying number developing within a cocoon. The larvae feed externally upon the Apanteles
