OF WASHINGTON. 79 



identified it as the tachinid, Hypostena barbata Coq., described 

 from New Hampshire and Southern California (Jour. N. Y. 

 Ent. Soc., v. Ill, p. 57), and not previously reared. 



This case is paralleled by that of the tachinid which is para 

 sitic on Diabrotica. This species, referred to Celatoria dia- 

 broticce, was first observed by the late Dr. Hy. Shimer in 1870 

 preying upon the striped cucumber-beetle, Diabrotica vittata 

 Fab., and an account of it was given in volume V of the Ameri 

 can Naturalist (p. 219), where it is described under the name 

 Tachina {Melanosphora} diabroticce. This parasite is quite 

 common about Washington and has been reared from the adult 

 beetles by the writer and others from July to September. 

 Celatoria craivit Coq., described from specimens reared in 

 California from Diabrotica soror (Insect Life, vol. II, pp. 233- 

 236) is a synonym. It has also been reared from Diabrotica 

 i2-punctata. 



OTHER PARASITES OF ADULT BEETLES. 



The subject of the parasitism of the adult of Eleodes sutu- 

 ralis, a large western tenebrionid, has been discussed by Dr. 

 Riley in former meetings of this Society (Proceedings, vol. II, 

 pp. 211, 219). 



Anomcea laticlavia, a common chrysomelid that affects 

 leguminous plants chiefly, is also parasitized in the adult state, 

 the writer having seen a larva that had crawled out of the body 

 of this beetle. 



Of interest as having some bearing on this subject is an obser 

 vation made upon one of the parasites of Tyloderma foveo- 

 latum. A larva of one of these parasites, presumably Eurytoma 

 tylodermatis or Catolaccus tylodermce, was observed, Septem 

 ber 3, fastened to a newly transformed adult of the curculionid. 

 All other parasitic larvae were attached to the larvae or pupas of 

 their host. 



Dr. Fitch once observed "a minute chalcidian parasite in the 

 act of ovipositing in the tip of the body of the female " of the 

 flea-beetle, Psylliodes punctulata (Tenth N. Y. Kept., p. 39).
