They were eaten, bones, and head, and claws and all, the 

 only remnant of the feast being a small ball about \ of an 

 inch in diameter, which was cast aside at the bottom of the 

 cage. 



The islands of Madeira, Porto Santo, and Deserta Grande 

 all lie within an area about fifty miles across. They have 

 each its own peculiar large Lycosa^ no two being alike 5 and 

 it is a very remarkable fact that these Lycosce vary in size in- 

 versely with the magnitude of the island in which they are 

 found, — Madeira, the largest island, having the smallest 

 Lycosa, and Deserta Grande, the smallest island, having by 

 far the largest spider. 



The mode of defence of all these varieties of Lycosce is pre- 

 cisely the same. They elevate the thorax, raise the first pair 

 of legs high up, and, opening wide asunder their falces, strike 

 at and seize any object, such as the end of a pencil, which is 

 presented to them, in a most formidable manner. 



Circumstances unfortunately prevented my bringing this 

 splendid spider away Avith me from Madeira, or I should have 

 tried to watch and record the remainder of its existence. 



Yours truly, 



Frederick Pollock.

XLI. — Remarks on Crinodes Sommeri and Tarsolepis remi- 

 cauda. By A. G. Butler, F.L.S., F.Z.S., &c. 



In the last Number of the ' Annals ' C. Ritsema, of Leyden, 

 accuses me of renaming an old and well-known species of 

 moth, Crinodes Sommeri, with the new generic and specific 

 names of Tarsolepis remicauda. 



C. Sommeri is figured by Hlibner in the second volume o\ 

 his ' Sammlung,' pi. 197 ; on pi. 196 both sexes of anothei 

 species ( C. Besclcii) , of which we possess a series in the British 

 Museum, are correctly figured. The latter is therefore the type 

 of the genus Crino, subsequently altered to Crinodes, and is 

 evidently so considered in Mr. Walker's catalogue. 



Hiibner states his figure to be a representation of a male 

 insect, as we should naturally conclude from the fact of its 

 possessing the male character of a well-developed anal tuft of 

 radiating scales. My insect is also a male, and differs from 

 C. Sommeri, as figured by Hiibner, in the following generic 

 and specific characters : —
