catch, and a second the day following : a third I found dead in a cobweb at the 

 entrance of a Bees' nest, and two others, very much mutilated, also in a cobweb. 



Hymenoptera. — Zarcea fasciata. — I took this insect, for the first time, at 

 Middlemarsh Common, this year. 



Banchus Farrani, (Curtis, pi. 588.) — Two specimens of this insect I took 

 twelve years ago, on Parley Heath. 



Bracon denigrator. — I took this insect, which is figured by Curtis, pi. 69, 

 near the Copse, at Parley Heath. 



Tengyra Sanvitali. — This, which is thought to be the male of Methoca Ich- 

 neumonides, I took a specimen of at Durdle Door, near West Lulworth, on a 

 thistle, on the 15th of July, 1835 ; and I took two more on the 11th of July this 

 year, one of which I gave to my friend, Mr. Curtis, who seemed surprised at the 

 capture, and did not previously possess a British specimen ; but he had taken 

 three or four of the Methoca, at Ramsdown, Hants, as well as at Black Gang 

 Chine, Isle of Wight, where the Rev. Mr. Rudd also took it, and to both of 

 whom I am indebted for specimens.* 



Hedychrum ardens, and Chrysis succincta. — I took these in company, at 

 Durdle Door, near Lulworth, which appears to be an excellent locality for choice 

 insects ; for, three or four years ago, I captured there, in the space of a week or 

 ten days, twenty or thirty species new to my cabinet, amongst which were Halic- 

 tophagus Curtisii, figured by Mr. Curtis in his British Entomology, pi. 433, 

 Hesperia Actceon, (Brit. Ent., pi. 442), Encyrtus pulchellus, Curt., and minute 

 Hymenoptera of the genera Eulophus, Ceraphron, Mymar, JRogas, Chelonus, 

 Aphidius, &c, in profusion. 



Cerceris ornata. — This I took last year, at Black Gang Chine, in August, as 

 also, 



Ccelioxys Vectis, (Curt. Brit. Ent., pi. 349). 



Osmia Tunensis. — It appears from the MSS. -of the late Captain Blomer, 

 that he bred this insect from the shell of a species of Helix ; and I possess a 

 memorandum of Osmia atricapilla having been also found in a Helix.\ 



• There is not the least doubt of the Tengyra being the male of the Methoca, for M. 

 Wesmael, of Brussels, has repeatedly taken them in copula. The Tengyra, was introduced 

 to the British Fauna, by our friend, Mr. Shuckard, in 1833, who captured two specimens 

 at Hampstead, as well as many of the Methoca ; and he informs us that he has taken a 

 single specimen of the Tengyra, in August, this year, at Birch Wood, in Kent Eds. 



f The specific name of the last Osmia should be xanthomelana, it being the Megachile 

 xanthomelana of Kirby, standing as such both in his Monographia and in his cabinet, which 

 is remarkable, as it is evidently a true Osmia. It is a question, worthy of determination, 

 which is the true instinct of the creature ? — whether to form a nest of clay for itself, as it 

 is shown to do by the observations and specimen presented by Mr. Waterhouse to the En- 

 tomological Society ; or to adapt the vacant shell of a Snail to the purpose ? We incline 

 for the former; yet, possibly, it may only build for itself in case of not finding a suitable
