INSECTA DIPTERA. 187 



discriminated byLoew. (Ent. Zeit. p. 20-1, 240, 258.) New species are Chr. 

 longlcornls, from Asia Minor, simplex, incisa, Macquarti, from Posen, hirtella, 

 insignls, plumbago, brevlcornlsfrontalls,fumlpennls, the two latter also from 

 Asia Minor. 



The Silesian species of Splieglna have been reviewed by Zeller. (Ent. Zeit. 

 p. 302.) A new species has been discovered by the author, Spit. Loewii, 

 besides which occur Sph. clunipes, nigra, Meig., and eleyam, Schumm. 



CONOPAE.II. A number of new extra-European species of Co/tops have 

 been described by Macquart (Dipt, exotiq.) viz., 1 from Senegal, 2 from 

 the East Indies, 4 from South America, 3, North America, and 2, locality 

 unknown. 



(EsTiiiDES. Clark (Trans. Lin. Soc. xix, p. 81) has given a supplement 

 to his well-known work on this family, in which besides (E. pictus, Meig., 

 lately found also in England, two new species, (E. Llbycus, from Egypt, and 

 (E. Clarkii, Shuck., (strange compliment !) from South Africa, have been 

 described. Besides this are several remarks and corrections, from which 

 we select the following. 1. (E. Trompe (stimulator, Cl.) the author is dis- 

 posed to regard as the male of (E. Tarandi, since both occur in the same 

 localities, and females only of (E. Tarandi are met with, whilst all 

 the (E. Trompe appear to be male. This opinion is not new. Modeer 

 says " probably Trompe is the male of Curbma ((E. Tarandi) or of the nose 

 Gadfly of the Reindeer." The latter appears to have more probability in its 

 favour when the difference in the occurrence of both is considered : (E. 

 Trompe is found, also, in Germany, probably living on the red Deer, 

 whilst (E. Tarandi is never seen there. (The red Deer has, as is well- 

 known, also a bot of the hide, which has not yet been ascertained : may it 

 not, perhaps, be identical with that of the Reindeer ?) 2. (E. ericetorum, 

 Leach, is declared by the author to be the male of (E. boms. 3. (E. 

 pecontm, P., he would unite with (E. veterlnus as a variety ; it is, however, 

 the female of a distinct species infesting the Horse, and with which he is 

 unacquainted. 4. (E. Clarkii, Leach, the author has found to be a light- 

 coloured variety of (E. veterlnus. 5. As the consequence of careless com- 

 pilation, the author regrets to find, in the works of Meigen, Megerle (sic !) 

 and others, the (E. lineatus, De Vill, described as a distinct species ; 

 it is unquestionably (E. bods. 6. He goes too far when he considers it below 

 the dignity of man to possess a peculiar (Estrus and consequently denies the 

 existence of the old South American (E. homlnls.* Finally, 7, the author 



* In spite of the rather forced explanations and little jokes, by which the 

 author attempts to set aside the (Eslrus homlnls, its existence, i. e. the occur- 

 rence of a larva in cutaneous swellings, has been confirmed by later tra- 

 vellers ; Schomburgk had even brought the insect which was reputed to be
