ENTOMOLOGY. 1069 



Cecidomyia destructor and C. avence by Dr. Paul Marchal, Government 

 Entomologist of France. From C. destructor Marchal bred the follow- 

 ing: Bceotomus {Micromelus) rufomaculatus, 5 ; B. coxalis, n. sp., $ 2 ; 

 Merisus destructor, $ 2; Holcwus cecidomyice, n. sp.; Eupelmus atro- 

 purpureus 9 $ ; Polygnotus {Platyg aster) zosine, S . A single male 

 specimen of Isosoma hrevlcome was found in the lot and Marchal 

 reports Oscinis pusillus as occurring in oat stubble. The specimens of 

 Bceotomus coxalis were found at Poitou and in various parts of Vendee 

 in France. It was also bred by Marchal from Cecidomyia (Oligastro- 

 pit us) arena' infesting oats. According to Ashmead the species comes 

 near B. {Merisus) subapterus of Riley; but it is readily distinguished 

 from that form by the metallic coxa-, darker flagellum, the longer 

 funicular joints, and by its broader and more depressed abdomen. 

 From Merixus inicroptera Lind. it seems fairly distinct. 



In the winged form the female has a length of 2 mm., is of a general 

 bronzed green color, with purplish head and lower part of thorax. 

 The palpi are white; the scape of the antenna', except apically, and 

 the legs, except the coxa?, are brownish yellow; while the knees, the 

 tips of the tibia and the tarsj, except the last joint, are yellowish white. 

 The flagellum is brown, subclavate, and pubescent. The male, or subap- 

 terous form, is usually mm. in length. It is of the same general 

 color as the female; the scape and pedicel are brownish yellow; the 

 flagellum is filiform, dark brown, and clothed with a fine pubescence. 

 The mandibles are quadrideutate and ferruginous. The coxse are 

 metallic and the abdomen black, becoming brassy towards the base.' 



Holcceus cecidomyice is a somewhat larger insect; the thorax is olive 

 green, the scape, trochanters, knees, tibia, and the tarsi, except the 

 last joint, honey yellow. It was bred in June from the Hessian fly 

 attacking wheat. According to Ashmead, it is closely related to 

 H. torymoides of Thomson, but is readily distinguished from that form 

 by the color of the female, the shorter abdomen, the relative length of 

 the segments, and the flagellar joints. The male is very readily dis- 

 tinguished by the very long joints of the flagellum clothed with black 

 instead of white pili. 



From Cecidomyia arena 1 Marchal bred Ba'otomus coxalis, Merisus 

 destructor, Homoporus lunigcr, Eupelmus atropurpureus (=atrocceruleus 

 of Thomson), E. degeeri, Trichacis (Platygaster) remulus, Polygnotus 

 (Phitygaster) minutus, and Anaphes pratensis (an egg parasite). With 

 them were found specimens of Isosoma brevicorne which is thought by 

 Ashmead to be a gall maker on oats, since most of the specimens were 

 bred from insects taken from oat stubble. 



From Cecidomyia tritici a single species, Merisus destructor, was 

 bred.
