The attraction of sugar to insects was then brought up, and Mr. Claggis 
who had collected during the past season in the Isle of Jamaica gave the result 
of his experience. Sugaring trees. was without result. The flowers exercised a 
superior attraction. Flowers were so abundant that collecting at them was 
tedious, so he tried sugaring flowers, and with complete success. The flowers 
artificially sweetened swarmed with insects, while the others were deserted. 
Large Bombycidae too came to this bait that never came to sugar on trees. Other 
members gave their experiences with flowers as an attractor and Mr. Smith gave 
the result reached by Mrs. Fernald as stated by Prof. Fernald at the meeting of 
the Ent. Club of the A.A.A.S 
Messrs. Hulst and Holland discussed the date of the appearance of Argynnis 
diana in N. C. finding it ranged from latter part of June to the middle of August.

On our table is a ‘‘Synopsis of the North American Trichopterigidae’ by 
Rev. A. Mathews, Gumley, England. Dr. Mathews is a well known authority 
on the family here monographed by him, and having the advantage of the mat- 
erial in the collection of Dr’s. Leconte and Horn, his work is up to the present 
state of American collections. Significant is this passage in the introduction 
“The Trichopterigidae are probably the most extensive Family of the Coleoptera”. 
Less than 100 species are catalogued in the paper, and there is a very large field 
therefore for collectors who will seek out these minute forms. The paper is an 
excellent one, and is published in the Trans. Am. Ent. Soc. XI, pp. 113—156. 
We have also a “Synopsis of the Philonthi of boreal America” from the pen 
of Dr. Horn. This was a work much needed, because so many species in col- 
lection were named by Fauvel. but not described, and oft times the mss. name 
was synonymous with one before given or the species had been previously de- 
scribed. Great confusion therefore existed in collections. Dr. Horn now gives 
usa simple easily comprehended classification, dividing that part of the genus 
treated of by him into three genera—Philonthus, Actobius and Cafius — and about 
118 species. The paper is published ‘Ir. A. E. Soc. XI, pp. 177—244.
