Neuronia clathrata in the London district. — With reference to the occurrence 

 of this insect in the Tottenham Marshes {cf. Ent. Mo. Mag., xxiv, p. 173), it may be 

 well to mention that I have seen another example, taken by Mr. Boden at the same 

 place on June 2nd of this year. He has obligingly indicated to me the exact 

 locality, but in consequence of the bad weather and other causes I have not been 

 able to visit it. — E. McLachlan, Lewisham, London : July 11th, 1888. 



Apanteles ferrugineus, Peinh. — This little ichneumon was discovered by Mr. 

 Porritt, who bred it from larva? of Chilo phragmitellus ; it has also been bred by 

 Mr. W. H. B. Fletcher from larvas of Macrogaster arundinis from Wicken Fen ; 

 from this it would appear to confine its attacks to larvse feeding in the stems of 

 Arundo phragmites. I should be much obliged if Entomologists would kindly let 

 me see the ichneumons they may breed from this source ; I think it very probable 

 that Apanteles ferrugineus is not so scarce as it seems to be, but that its habits have 

 screened it from observation. — John B. Beidgman, 40, St. Giles', Norwich : June 

 23rd, 1888. 



Some insects common to Europe and Colorado. — Packard, in the Ann. Rept. 

 U. S. Geol. and Geog. Survey for 1873, has a very interesting paper on the moths of 

 Colorado, in which he records several species which are common to Europe, and 

 mostly, at any rate, belong to the boreal fauna. It may be of some interest in this 

 connection to give a list of such species of insects common to Europe, as I have 

 myself met with during the past year in Colorado, although it cannot be considered 

 in any sense complete, many of my finds not yet having been examined by those 

 competent to determine the species : — 



PMlonthus ceneus, Rossi. — Straight Creek, near Dillon, Summit Co., alt. about 

 8850 feet : frequent. Aphodius granarius, Linn. — Near Swift Creek, Custer Co., 

 alt. about 8300 feet : common. Clirysis cyane.a. — Mr. T. R. Billups so named a 

 Custer Co. Chrysis, but to me it seemed a different species. Pieris napi. — Repre- 

 sented in Custer Co. by the form oleracea, Bdv., and seasonally dimorphic. Danais 

 Plexippus, Linn. — Custer Co. : abundant. Vanessa Antiopa, L. — Custer, Summit, 

 Eagle, Garfield, Mesa and Delta Counties : abundant. V. cardui, L., and Y. 

 Atalanta, L. — Swift Creek, Custer Co. : the first abundant. Cidaria (Petrophora) 

 populata, Linn. — Custer Co., 1887. Nomophila noctuella, Schiff. — Saguache Co., 

 1887, and Packard records it from Park Co. Lucilia Casar, L., Musca domestica, L., 

 and Cimex lectularius, L. — Custer Co., &c, about houses. — T. D. A. Cockeeell, 

 West Cliff, Custer Co., Colorado : June 16th, 1888. 



British Diptera. — This being the height of the collecting season, I should like 

 to call the attention of Entomologists to the Diptera of this country. This order, 

 neglected for so long, is now being thoroughly revised, so far as the British species 

 are concerned, and a vast amount of assistance can be rendered by Entomologists in 

 general by the capture of these insects during excursions. 



Diptera should be pinned with Carlsbad (long, thin) pins, and placed high up 

 the pin ; they need not be set, but dates and localities should invariably be appended. 



It may be remarked, for the benefit of the ambitious, that there is a good chance 

 of distinction in this direction, as species new to the British fauna are continually 



being added.
