Starch grains vary in form, the acorn starch being more or less elon 

 gated in form and often somewhat truncated. They possess faint concen 

 tric rings and a hilum marking which tends to be crescent-shaped. 



The gall starch grains are nearly spherical in form, occasionally trun 

 cated, and usually have a strongly-marked stellate hilum. The rings are 

 more strongly shown than in the acorn starch. Both varieties are rather 

 strongly active toward polarized light. 



The starch grains from the galls resemble somewhat the reserve (?) 

 starch of the woody tissue though the markings are rather more pro 

 nounced." 



Dr. Hopkins stated that the galls appear to belong to a group 

 designated by Osten Sacken as " swellings of the leaf, usually 

 along the principal midribs, and containing numerous seed-like 

 kernels." No specimens have been reared from the galls, but 

 they appear to be the work of a species of Callirhytis. 



Another gall on oak twigs, from Miss Alice Eastwood, San 

 Francisco, California, was exhibited, which contains hazelnut- 

 like kernels which readily separate from the enveloping woody 

 swelling. This gall was identified by Mr. Ashmead as probably 

 belonging to the genus Callirhytis. 



In discussion Mr. Ashmead then stated that the gall-maker 

 might not be a true Callirhytis but an Andricus. 



Mr. Busck stated that a box containing lost types of Clemens 

 Tineids had recently been found in the Academy of Natural Sci 

 ences, Philadelphia. As a result of this valuable discovery 

 twenty species of Clemens, which have up to this time been 

 only guessed at, are now definitely known from the type speci 

 mens. 



Mr. Heidemann exhibited specimens of all stages of the 

 Reduviid bug Apiomerus crassipes Fabricius. The larvas and 

 eggs shown were received from Mr. F. C. Pratt, who collected 

 them upon a leaf at Great Falls in Virginia. 



Mr. Busck exhibited some peculiar woody balls which he had 

 found in nests of Eutermes in Porto Rico. In the majority of the 

 nests they were not found, but in some they were very numerous. 

 Prof. Hopkins said he thought that Mr. Pergande had hit on the 

 right idea in believing that these balls were condensed, stored 

 food material. 



Dr. Dyar showed mosquito eggs, presumably of Culex 

 triseriatus Say, which had been collected by Mr. J. Turner 

 Brakeley, of Homers Town, New Jersey, at his suggestion. Mr.
