6610 Insects. 



engaged in this operation. In shape and general appearance it is closely allied to the 

 larva of Eupithecia tenuiaia, The pupa is enclosed in a very tightly-spun earthen 

 cocoon. The thorax and wing-cases are green, and the abdomen red. The perfect 

 insect appears in June and the beginning of July, and is abundant among Clematis 

 vitalba: it flies about with extreme rapidity in the hot sunshine, and it is almost 

 invariably wasted when caught; when fresh the upper part of the abdomen is orange. 

 The larva feeds very rapidly. — H. Harpur Crewe; Breadsall Rectory, Derby, June 4,

Description of the Larva of Eupithecia innotata. — This larva has, I think erro- 

 neously, been said to feed upon various low-growing plants : I have been 

 acquainted with it for some years past, and never beat it from anything but ash. It 

 is long, smooth, rather slender and tapering towards the head. The ground-colour is 

 a uniform dark green, with a waved, yellowish spiracular line. The segmental 

 divisions are yellow, and on the anal appendage is a dark purplish spot. The belly is 

 whitish, and wrinkled with a dark green central line running the whole length. It 

 feeds upon ash, and appears to prefer the tall suckers in hedge-rows. It is widely 

 dispersed, but nowhere common. It is full fed from the end of August to the middle 

 of September. The pupa is long, rather slender and tapering. The thorax and wing- 

 cases are dark olire ; the abdomen still darker, almost black, tinged underneath with 

 red. It is either enclosed in a slight earthen cocoon, at the foot, or under moss on 

 the trunk, of the tree. My friend Mr. Greene has already given the entomological 

 world directions how to find it. The perfect insect appears in June and July. — Id. 



Observations on the Species of the Genus Prosopis of Fabricius, 

 belonging to the Family Andrenidce, with Notes on the Economy 

 of P. dilatatus. By Frederick Smith, Esq. 



In the year 1842 my first Hymen op terous Essay was published in 

 the e Transactions of the Entomological Society ;' it contained descrip- 

 tions of nine British species of the Genus Prosopis (Hylaeus) ; since 

 that period much additional material has come to my hands. In the 

 year 1848 I again published descriptions of the species : at that time 

 I had not acquired much additional information, but added one species 

 and reduced a second to a synonym. In my 'Monograph on the Bees 

 of Great Britain,' published in 1855, I again added a species, and 

 reduced another to a synonym : the latter circumstance was inevitable, 

 having obtained the nest of P. cornutus, from which I bred P. plantaris 

 (male) and P. cornutus (female). 



In the 'Entomologist's Annual' for 1859, I announced the capture 

 of a specimen of the rare P. dilatatus, and also noticed the fact of 

 having found a stem containing the nest of a species of Prosopis, which 

 I expected would prove to be that of P. dilatatus : this opinion has 

 proved to be correct, but I was not prepared for the entire results ;
