Malvarum, to whicli Linneus's description is generally referred, does not appear to 

 occur in N<irlh Europe at hII. 



"Genus Cyclopides, Hiib. (Sleropes, fl<i.) — Boisduval's name is quite inad- 

 inissible, as it is ilie specific name of ihe type of liis genus, for wliicli lie uses the name 

 Arminllius, given to ihe insect eipiileen years afier llie former one. His jjenus Syiicli- 

 thus (Pyr;;us, H'lib.) is also objectionable, as it is the Fal)rician synonym of the 

 North American Oileus of Liuneus, a species most certainly belonging to Boisduval's 

 genus Syricbihus."

Mr. W. C. Hewitson communicaled " A Monosraph of the Genus Ypthima, with 

 Descriptions of two New Genera of Diurnal Lepiiloplera." The new -jenera C.tnyra 

 and Xois consist each of a single species — Coenyra Corycia, from Natal; and 

 Xois Sesara, from Fiji. Of Ypthima tweiiiy-four species are ennmeraied, of which 

 seven are new, viz., Y. Inica (East India), Y. Itonia (White Nile), Y. fasciata (S.ira- 

 wak, Sumatra), Y. C.yl.mica (Ceylon), Y. Loryma (Macassar, Celebes), Y. Methora 

 (Noith India), and Y. Sepyra (Gilolo, Batchian). 



Caitain HutioD, of Mnssooree, N.W. India, communicated a paper "On the Re- 

 versiim and Restoration of ihe Silkworm." In this, the concluding part of a former 

 communication to the Society (see 'Tran.saclions,' 3rd series, ii. 143), the author de- 

 tails the progress of his experiments durinu 1864, vviih a view to the restor.ition of the 

 silkworm to its pristine state of health. The selected black worms were hatched on 

 the 21-1 Miirtdi, some of the eirgs having been laid in the spring and others in the 

 autumn of i8H3 ; all were decidedly unhealthy, the autumn batches less so than those 

 of the spring ; the latter were so terribly afflicted with jaundice, and wiili sou)e disease 

 that turned the winms dull green, th:it the whole of ihem had to be thrown away. The 

 worms from the autumnal batch of eggs went on satisfactorily and spun good cocoons, 

 the moths from which deposited a goodly number of eggs at the end of May, and these 

 began to hatch for a second crop in Sepieuiber. With a few of this brood the author 

 expresses his intention of carrying on his experiments for amusement, but he now feels 

 fully persuaded that the consiituticm of the worm has been so thoroughly undermined, 

 ihiit, although it may be restored to its natural appearance, it will never be able to 

 shake off the various diseases to which it has so long been snbject. The only way 

 open to the sericultiirist is therefore to re-seek, in the original habitat in Cliina, for the 

 wild worms in their natural slate of freedom on the trees, and, should any be pro- 

 curable, the entile stock in Europe may be gradually renewed. The author, after 

 arguing at len<;lh a<:aiiist the opinion of Indian sericiilturists that the several forms of 

 silkworm are but varieties of a single species, then proceeds to evolve eighteen silk- 

 producing species ol Bomhycida-, twelve belonging to the genus Bonibyx (mx domes, 

 ticated and six wild specie-), five belonging to the genus Ocinara, the remaining one 

 being the Trilocba varians of Moore.
