Another interesting point is that there are as a rule many more 

 egg punctures in a stem than will be adults developing from that 

 stem. For example on a stem examined July 29, of 85 egg punc- 

 tures, over half contained collapsed eggs or nothing. This is due 

 in part to parasitism, but there is also some other factor concerned. 

 Girault has described a species which he bred from the egg of Tylo- 

 dcrma foveolata, known as Anaphoidea sorditata Gir. (Jour. N. Y. 

 Ent. Soc, Vol. XVII, p. 169, 1909). We have obtained this species 

 from eggs collected at Woodstown and several localities in the 

 northern part of New Jersey during June and July. 



In addition to the egg parasites there are also several species 

 attacking the larvae. Pierce (Bui. 73, Bui. 100, U. S. Bur. Ent., 1908, 

 1912) has recorded several parasites of this species. He states: 

 "It is highly parasitized by Neocatalaccus tylodermce, Urosigalphus 

 sp., Cerambycobius cyaniceps, Eurytoma tylodermatis, Microbracon 

 mellitor, and Sigalphus curctdionis. The four last species are also 

 parasites of the boll weevil. At Trenton, N. J., on September 7, we 

 bred A^. tyloderma from stems of primrose infested by Tyloderma 

 foveolata." 



The parasites infest the larvae in the burrows. On several occa- 

 sions we have observed the parasitized larvae and parasitic cocoons 

 in the burrows as late as November. From these, adults have been 

 secured later. From this it appears that the parasites pass the winter 

 as pupae in the burrows and emerge the following spring. 



Acanthoscelis acephalus Say. 



This species has long been known as a frequenter of evening 

 primrose and as a feeder in the axils of the leaves. Hamilton credits 

 it to Polygonum, especially P. hydropiper, but it is extremely similar 

 to Acanthoscelis curtus which lives on Polygonum, there is here a 

 possibility of error. It ranges according to Blatchley and Leng 

 (Rhyn. N. E. Amer.) from Canada and New England to Michigan, 

 Colorado and Kansas south to Georgia. It is frequent throughout 

 Indiana, May 23 to August 2, on evening primrose. Smith (Ins. 

 N. J.) records it as common all along the shore of New Jersey from 

 May to September on the same plant. As a matter of fact it is quite 

 common all over the southern half of the state and occurs more or 

 less abundantly at such inland places as New Brunswick, Riverton,
