STATED MEETING, July 11. 



President Bland in the Chair. 



A communication was read from Mr. Bland reporting the capture 

 by him in New Jersey, during June, of the following Coleoptera : — 

 Alaus m^opg, Boras unlcolor^ Htlops gracilis, Brontes fhibius and 

 Elater rubricof/is, under the bark of pine trees; Cacoplia pruinosa 

 on the Oak, and Strnn//alia acuminata and Leptura nitens on flowers. 

 On July 4th he captured a considerable number of Ancylochira linc- 

 ata and also its supposed variety maculipennis. Mr. Bland expressed 

 his doubts about macidipennis being a variety of lineata, as each spe- 

 cies seems to have their distinct markings and not varying so as to 

 make one have the least resemblance to the other ; they were both 

 taken from the same kind of tree, and each species were found in coitu 

 and in no instance were they amalgamating. Ou the same day he cap- 

 tured two fine specimens of Chrijsohofhris concinnula Lee, on the Oak 

 being, to his knowledge, the first specimens collected in this locality, 

 the typical specimen having been taken in Missouri. Acanthodc.res 

 decipie7is, Liopus varicf/atus, Eapogonius tomentosus, Pogonocherns 

 mixtus, Adrastus testacms and Megapenthes rufilahris were part of 

 the captures by beating bushes. 



Also the following communication from Mr. H. F. Bassett, dated 

 Waterbury, Conn., June 28th, 1864: — 



I have this afternoon discovered a fact relating to the Cynips, or to one spe- 

 cies rather (C. q. operator Osten Sacken), which you may, if you think proper, 

 communicate to the Society at your next meeting. It seems to me to be quite 

 important, throwing light upon some of the most difficult questions relating to 

 the economy of this family. 



Baron Osten Sacken {Proa. Ent. Soc. Philad. I. p. 248) asks, " Have the gall- 

 flies of the Oak-ai)ples one or two generations?" and at the close of his remarks 

 on that subject declares " the question still undecided." The same subject is 

 referred to in an earlier article on the Cynipidse {Proc. Ent. Soc. Philad. I. p. 

 51), when speaking of his C. q. palusfris, a species that appears in May. He 

 asks: " May not this gall-fly have a second generation, and if it has, may not 

 the gall of this second generation be different from the first produced, as it 

 would be under different circumstances, in a more advanced season, jserhaps, 

 on leaves instead of buds?" 



Dr. Fitch states {N. Y. Pep. II. ^315, p. 33), that C. q. seminator Harris, pro-
