more numerous in the Canaries, owing to the African charac- 

 ter of the Islands of Lanzarote and Fuerteventura ; whilst, 

 on the other liand, the deHciency in Necrophaga, Pseudotri- 

 mera and Brachelytra may be generally attributable to the 

 fact that these sections find a maximum in more northern 

 latitudes. Amidst about a hundred novelties, the discovery 

 of Buprestis Bertholeti in the Pirial of Hierro, after nearly 

 thirty years' obscurity, may merit a passiug notice, especially 

 as its very existence has of late years been called in ques- 

 tion. In conclusion, I should feel extremely obliged for any 

 notes, especially geological and botanical, with reference to 

 these Islands, or the cognate groups of the Cape de Verdes, 

 Azores, &c., and especially the north-west coast of Barbary.

Description of the Larva of Nemeobius Luci?ia (Duke of 

 Burgundy), — The eggs are laid about the 1st of June (I give 

 this as a medium date, having no doubt that the period of 

 oviposition may extend over twenty daj's), on the under side 

 of the leaves of Primula veris (cowslip), either singly or in 

 clusters of four or five ; their shape is spheroid, depressed at 

 the south pole or base, and produced at the north pole or 

 apex ; their colour is pale glaucous. The larva emerges 

 about the fourteenth day, and remains on the under side of 

 the cowslip-leaf, in which it makes small round holes, thereby 

 indicating iis presence ; it continues to feed for several weeks, 

 the duration of the larval state being dependant on tempera- 

 ture. When full-fed, it rests with its under surface closely 

 appressed to the leaf; but if touched or annoyed it falls from 

 its food-plant, lying motionless on its side, and bending its 

 body in a crescentic form, the two extremities approaching, 

 but not meeting. Head narrower and every way smaller than 

 the 2nd segment, into which it is received and sometimes 

 completely withdrawn ; body somewhat onisciform, the dor- 

 sal surface convex, the ventral surface flat; the legs and 

 claspers concealed ; the divisions of the segments deeply 

 incised and well defined ; each segment emits about forty 

 hairs or bristles, of which those on the back are slightly 

 arcuate, those on the sides straight. Colour of the head pale 

 wainscot-brown, glabrous and hairy, the hairs and ocelli
