386 REPORT ON ZOOLOGY, MDCCCXLIV. 



Uobineau Desvoidy (Ann. Soc. Ent. Fr. ii, 39) has characterized a new 

 species of Brachyopa, scutellaris, wliich, however, seems scarcely to be 

 different from B. bicolor. 



HENOPII. Loew has discovered in Asia Minor, and in the island of 

 Stanchio, a species of Philopota, a genus hitherto known as South American 

 only. The species, Ph. murina is described very particularly and figured. 

 (Ent. Zeit. 162, pi. 2, f. 17-21.) 



CONOPICA. Zetterstedt (Dipt. Scaud. iii, 9-12) has distinguished as a 

 species Myopa sundewalli, given by Fallen and Mcigen as a variety of 

 M. atra, from which it differs in having the third and fourth main veins 

 separate to the tip of the wing. The new species is also larger, and has 

 the abdomen gray with an indistinct black stripe down the back. 



PLATYPEZINA. In this family also several new species are added to the 

 Fauna of Scandinavia, Platypeza vittata, from Sweden and Denmark, PI. 

 modesta (Stag, in litt.), from Schouen and Seeland, PI. comobrina, from the 

 interior of Sweden, Callomyia zettcrstedtii (Wahlb. in Litt.) from Ostro- 

 gotliia. 



PIPTJNCULINI. The additions are Nephrocerus Jlavicornis, Zett., from the 

 south of Sweden, Pipunculus fuscipes (Stag, in litt.), P. nnicolor, fusculus, 

 fuscipes, obtusinervis, Zett. 



(EsTRiDES. Zetterstedt has characterized two new species, Gastrus 

 ferruginatus and nigritus. The first agrees with G. jubarum, Meig,, which 

 is the male of G. pecorum, only the band between the wings is brown, and 

 the black hairs on the breast are wanting ; it may be but a variety of the 

 species last named. So also the second, notwithstanding the different 

 colours of the pubescence (atro-villosus, pectorc antice abdominisque basi 

 cano hirtis, ano rufo-villoso\ may be a mere variety of G. uasalis, from wliich 

 the author separates G. salutaris also, on account of the black down with 

 which the fore thighs are clothed below. There is no difference between 

 them in the veining of the wings. Further observation will decide whether 

 the colour of the pubescence marks distinction of species in this case. 



The opinion which I expressed in the preceding Report (p. 187) with 

 regard to (Estrus tarandi and trompe, has been confirmed by Zetterstedt 

 (ibid.) and Bohemann. (Arsberatt. Zool. Framst. 1843, 18-11, p. ISO.) 

 Zetterstedt describes both sexes in each, and states that the larva of (E. 

 trompe lives in the frontal sinuses, in the throat, and under the tongue of 

 the reindeer, while (E. tarandi is well known as the bott of the hide. 

 Bohemann has found both the species paired. The two sexes of (E. trompe 

 present scarcely visible differences externally, and the $ of (E. tarandi also 

 resembles the $, except that the long ovipositor is wanting. Tliis sex is 

 not so commonly found, not being in the habit of hovering round the deer 

 as the female docs, but sitting still on stones, &c. [See Ann. Nat. Hist.
