seen only the female, I should probably have taken it for 

 Mo7iophlebus ; but the male has sixteen simple eyes in a ring, 

 and the characteristic antennse of Leachia, also no tassels on 

 the abdomen. I think you will consider this male as a fine 

 insect ; unfortunately, I can only send one. 



" Gossijparia is also new to this country. I hesitated long 

 before I fixed the genus, but it has very frequently only a 

 cushion of cotton with the dorsum exposed. I believe 

 Gossyparia ought to be united with Eriococcus. 



" Dactylojnus ohtectus is most peculiar, as it shelters itself 

 under the little red scale of a bud of the plant. It can only 

 be detected at sight by the little extruded cotton at the edges 

 of this bud-scale. I know of no other Dactylopid which does 

 this. 



" Sdenophora is a new genus, very peculiar from the ' spout ' 

 of the test. The male is in a narrow felted sac, like that of 

 Eriococcus. "What may be the use of this spout ? Scarcely 

 sexual ; at least neither CtenocMton, Ivylisia, nor any Diaspid 

 has any such apparatus." 



Mr. Lewis also exhibited some specimens of the larvae and 

 imagos, both male and female, of Icerya Purchasi (Maskell), 

 obtained from Natal, where it had proved very destructive to 

 orange, lemon, and many other fruit trees. Specimens were 

 also shown of the larva of an allied species from Natal, and 

 originally assigned by Mr. Douglas to the genus Ortonia, but 

 which Mr. Maskell is inclined to regard as a new species of 

 Icerya. The male of this insect has not yet been found. 



Mr. M'Lachlan and Mr. Elwes commented on the inte- 

 resting nature of the exhibition, and the importance of a 

 knowledge of the parasites of injurious insects, m connection 

 with which special mention was made of the researches and 

 discoveries of Prof. Eiley. 



Mr. H. Goss exhibited, on behalf of Mr. T. D. A. Cockerell, 

 of Colorado, a large collection of insect-galls, and read the 

 following letter from Mr. Cockerell on the subject : — 



"West Cliff, Custer Co., Colorado, March 21, 1890. 



" Dear Sir, — I have been so much interested in the rearing 



of gall-insects myself, that I venture to send you by this mail
