Mr. McLachlan exhibited a species of Halticidce, -which had been sent him by 

 Mr. D. Morris, Assistant Director of the Boyal Gardens, Kew, who had received 

 them from Mr. J. H. Hart, of the Botanic Gardens, Trinidad, with a note to the 

 effect that they had attacked young tobacco and egg plants badly in that island. 

 Mr. Jacoby had, with some reserve, given as his opinion that it might possibly turn 

 out to be Epitrix fuscata, Duv., a species which had been described from Cuba. 



The Eev. H. S. Grorham exhibited a collection of beetles lately captured in 

 Brittany, including Diachromus germanus, L., Onthophagus taurns, L., Sister 

 sinuatus, 111., and other species which are exceedingly rare, or altogether wanting in 

 Britain, and yet occur very commonly in the North of France. 



Mr. Enock exhibited specimens of the Hessian Fly bred by himself, and mounted 

 for the microscope. 



Mr. White exhibited living larvae of Endromis versicolora, and remarked that 

 when quite young they are nearly black, owing to being very thickly spotted with 

 that colour ; the body-colour is green, and after the second change of skin the spots 

 disappear. Mr. White also exhibited two preserved larvae of Phorodesma smarag- 

 daria, which he had recently taken, and made some remarks concerning the so-called 

 " case " which this insect is said to construct from the leaves of its food-plant, 

 Artemisia maritima. This he did not consider to be really a case, but he had 

 discovered that the larva possessed on its segments certain secretory glands, at the 

 apex of each of which there is a bristly hair ; this appears to retain pieces of the 

 plant, which are probably fixed firmly afterwards by means of the secreted fluid. 

 These pieces are very irregularly distributed, and their purpose is evidently pro- 

 tective. 



Mr. Lewis exhibited about three hundred specimens of the genera Hetcerius, Er., 

 and Eretmotus, Mars. The most remarkable of these was Hetcerius acutangulus, 

 Lewis, discovered last year by Mr. J. J. Walker, near Tangier, and were recently 

 taken by him at S. Boche, in Spain. The names of the other species exhibited are : — 

 Hetcerius Bedeli, Lewis, H. punctulatus, Lucas, H. cosmosellus, Fairmaire, H. 

 pluristriatus, Fairmaire, H. setulosus, Beitter, Eretmotus sociator, Fairmaire, from 



Algeria. Hetcerius acutangulus, Lewis, H. arachnoides, Fairmaire, H. , 



n. sp,, Eretmotus tangerianus, Marseul, from Morocco. Hetcerius hispanicus, Eosenh., 

 H. Marseuli, Brisout, Eretmotus ibericus, Brisout, from Spain. Hetcerius ferrugineus, 

 Oliv., from France.— W. W. Fowlee, Hon. Sec. 



OBSEBVATIONS ON COCCIBM (No. 1). 

 BY ALBERT C. F. MORGAN, P.L.B. 



In offering a few observations on the group of insects included 

 in the family of Coccidce, I am much indebted to Mr. Douglas for his 

 unremitting correspondence on the subject, and. for. the numerous 

 specimens with which he has furnished me, and I should also thank 

 Professor Comstock for his valuable and kind assistance. 



I propose now merely to glance at the different forms of scales 

 secreted by one of the sub-families into which the group has been 

 divided, viz., the Diaspince. Before, however, entering into this part 

 of the subject, it may be desirable to make a few general introductory 

 remarks.
