462 ME. A. G. BUTLEE ON 



round with the fly (still struggling), held in his left chela. 

 After three minutes the movements of the fly ceased. Then the 

 Scorpion brought the fly up to its chelicerse, and released its 

 hold with the left chela. The fly was now carried by the two 

 chelicerse, the chelae being left free. I did not observe in these 

 small Scorpions any thing of the method of getting out the juices 

 of their prey, 



I am inclined to think that the species of Euscorpius do not 

 so readily prey upon their own kind as does Androctonus funestus, 

 and as does the Spanish Scorpion allied to A. funestus, namely 

 the A. occitanus, or yellow Scorpion of Southern France and 

 Spain*. According to Maupertuis, in six weeks one hundred of 

 these A. occitanus, kept by him in a cage, were reduced in number 

 to ten, one having eaten another, until at last only these few, 

 presumably the embodiment of the whole hundred, were left. 



I trust that these few fragmentary observations may induce 

 others, who have enjoyed greater opportunities, to place on record 

 their experiences as to the habits of various species of these 

 notable and historic Arachnids. 



On the Butterflies collected by Lord Walsingham in California.

 Zoological Department, British Museum. 



(Eead March 2, 1882.) 



The collection of which the following is an account consists of 

 about eighty species obtained by Lord Walsingham during the 

 years 1871 and 1872 in California, one species only (which I 

 believe to be the Thecla auretorum of Boisduval) being taken in 

 Oregon. Compared with other collections from this country, the 

 present is by no means poor in species : the first series forwarded 

 by M. Lorquin to Dr. Boisduval contained 83 species of Butter- 

 flies ; but some of these may have been received from Mr. 

 Doubleday, since Dr. Boisduval says : — " Toutea les especes men- 

 tionees dans cet opuscule ont ete recueillies par M. Lorquin, a 

 I'exception de cinq a six, qui nous ont ete donnees par M. 



* Since writing the above, I have found three small Euscorpii, killed and 

 their juices sucked, in a box sent to me containing eight live specimens when 

 despatched from Italy.
