species in need of protection as shall be drawn up, and, if necessary, from time to 

 time amended bj the Committee of the Entomological Society of London appointed 

 to that end." 



The draft of alterations and additions to the Society's Bye-Laws, recommended 

 for adoption by the Council, was read for the first time. Mr. McLachlan showed, 

 on behalf of Mr. Gerald Strickland, a magnified photograph of Brachycerus apterus, 

 obtained by direct enlargement in the camera, and extremely clear in definition and 

 detail. Mr. Tutt exhibited some of the silk used by Tephrosia bistortata to cover its 

 ova, and discovered by Dr. Riding. It was contained in a pouch at the extremity of 

 the abdomen in the form of dense bundles about 2 mm. long, and resembling in 

 miniature locks of wavy flaxen hair. Hitherto all such coverings were supposed to 

 consist of scales from the anal segment. Papers were communicated by Prof. Miall, 

 F.R.S., on "The Structure and Life-history of Limnohia replieata" and by Messrs. 

 Godman, F.R.S., and Salvin, F.R.S., on " New Species of Central and South 

 American Rhopalocera." — W. F. H. Blandfoed, Hon. Sec.

Classification of Species of the 4th Section of Pericoma. 



A. Radius linked to or confluent with the cubitus at a distance beyond the anterior 

 basal cell less than the cell's apical width. 



* Bristling hair wanting on the subcosta, prsebrachial and anal nervures ; its 

 endings on the pobrachial branches and postical arranged in a re- 

 entering angulate line with one another. Penultimate (15th) joint 

 in the $ antenna; bulbose, with a short, cylindrical or filiform beak ; 

 scape clad with hair, mingled with a few short inconspicuous scales ; 

 . 1st joint obovoid, slightly compressed ; 2nd shorter and globular; 3rd 

 subequal in length to the 4th, bulbose, with a tapering beak and an 

 ample verticil of hair ; the succeeding joints bulbose with filiform 

 beaks ; for articular appendages, an inner verticil of short, dense, soft 

 hair or a pair of opposite expanded fascicles of hairlike scales. Superior 

 (J genital appendages similar in pattern to those of species of the 3rd 

 Section. 

 A. Bristling hair in parts of the wing extended beyond the shortest line 

 drawn from the end of the subcosta to the end of the postical 

 nervure ; its endings on the posterior radius and cubitus distant 

 from the radial bifurcation, and approximated to each other 

 beyond its ending on the anterior radius, which is near the bifur- 

 cation ; its ending on the anterior pobrachial opposite that on the 

 posterior radius ; that on the cubitus either in line with these or 

 a little beyond them ; its endings on the pobrachial branches and 

 postical nervure in an obtusely or almost rectangulate line with 

 one another, the angle re-entering 27. P. ustulata.
