tennal joints in the sexes, scutellar bristles, larvipositor sharply 

 pointed at tip or not, from description of Eutrixoidcs Walton (Ent. 

 News, Vol. XXIV, pp. 50-51); measurement of Chcctophleps crassi- 

 nervis Walton (/. c, pp. 51-52) ; and color and form of palpi from 

 description of Cryptomcigenia auri fades Walton (Proc. E. S. Wash., 

 Vol. XIV, p. 199). Mr. Walton points out that the best view of the 

 thoracic vittse may be obtained from the rear at an angle of about 

 45°, but he overlooks the fact that there are often present an extra 

 pair of median vittee or an unpaired median vitta behind suture only 

 visible from in front. 



Mr. Walton states in the last cited article that Cryptomeigenia 

 theutis and Etitrixa exile are the only species up to that time recorded 

 as parasitic on adults of Lachnosterna. He overlooks the record of 

 Viviania lachnosterncc (Towns., Tax. Muse. Flies, p. 106). It would 

 seem more probable that this species came from an adult carabid inad- 

 vertently introduced into the cage with the Lachnosternas, but the 

 possibility of the Lachnosterna record being correct must not be lost 

 sight of. 



Another point to be mentioned in connection with Cryptomeigenia 

 is that two distinct forms appear to be confused under this generic 

 name. C. aurifacies Walton appears to be Emphanoptcryx Towns, 

 on the character of the acutely pointed and exserted ovipositor. In 

 Ann. E. S. Am., Vol. IV, pp. 140 and 329, the piercer-like organ of 

 Emphanopteryx female is mentioned. The writer's only reason for 

 claiming the absence of this organ in the female of Cryptomeigenia is 

 based on a dissection and mount carefully made by Mr. W. R. Thomp- 

 son at the Gipsy Moth Laboratory, June 11 to 16, 1909. A female of 

 C. theutis, determined by Coquillett, was relaxed, abdomen soaked up 

 and " found to contain a coiled uterus with flattened Tachina-like 

 eggs showing maggots with mouth-hooks" (Thompson). The hypo- 

 pygium of this specimen was removed, cleared and mounted in balsam 

 on two slides, with resulting record of " no piercer such as is present 

 in Emphanopteryx eumyothyroides T. is visible" (Thompson). This 

 specimen is TD1828. Female of Emph. cnmyotliyroides (det. Towns.) 

 was present for comparison and possessed the same acute exserted 

 ovipositor figured by Walton for his C. aurifacies. 



It may be noted here that Emphanopteryx doubtless deposits incu- 

 bated eggs containing the more or less fully formed maggot, and prob-
