220 ENTOMOLOGICAL NEWS. [May, '15 



would grow out, so to speak, of the acorn and drop to the ground, 

 "growing out" by means of fleshy stalks which would extend them- 

 selves and push the larval cases out. The dropping of the cases "made 

 a continual patter," resembling that of rain on the foliage of trees in a 

 forest. Upon examining the acorns, the teethlike larval cases were 

 found to be arranged in a row at the base of the kernel of the acorn 

 where they fitted into cavities ; each one was upon a fleshy stalk ; an 

 acorn may contain from 4 to 6 of them. They are double, the inner 

 case being pea-shaped and holding the larva. The larvae continued 

 alive up to October 2, but died during the winter. The identification 

 was through the kindness of Dr. L. O. Howard. 



Callirhytis seminator (Harris) in Maryland and Virginia (Hym.). 



By June 7, 1901, pupae were present in the galls of this species at 

 Annapolis, emergence following about one week later. On June 16, the 

 same year at Blacksburg, Virginia, adults were emerging, continuing 

 up to July 3. 



Syneches thyridopterygis (Riley) (Hym.). 



This parasite was reared from the overwintered bags of Thyridop- 

 teryx ephemerae formis Haworth at Annapolis, Maryland, June, 1901. 

 The identification was by Ashmead. 



Laelius trogodermatis Ashmead (Hym.). 



In the original description of this species no mention is made of the 

 carinae on the metathorax of which, in this species, there are 9, the 

 five mesial ones complete, the two in the dorso-lateral aspect abbre- 

 viated caudad, not running quite half the length of the segment. The 

 scutellar impression is crescentic. These notes from a single female 

 identified by Ashmead. 



The Trichogrammatid Genus Ophioneurus (Hym.). 



For probable description of development of this genus, see Ganin, 

 Zeitschr. f. Wiss. Zool., XIX, pp. 381-451. 



Metamymar aleurodis Riley MS. and Pteratomus putnami Packard 



(Hym.). 



The former mymarid has been overlooked. I do not know what it 



is nor whether it is described in the following reference : Fourth Rep. 



U. S. Ent. Commission, p. 107, note 29a. It is probably a nomen 



nudum. For figure of the rare Pteratomus see Amer. Naturalist, 



1878, XII, pp. 445-448. 



Polynema bifasciatipenne (Girault) (Hym.). 

 I find a reference under morphology of Mymaridae to Ayers on 

 Teleas in Memoirs Boston Society of Natural History, III, 1884, pp. 

 261 f?. After Teleas, for some reason I had written "(= Polynema 

 bifasciatipenne?)" Also I noted Ayers' references to Filippi and a 

 marginal note referred to Packard's and Balfour's embryologies.
