genera of Asilidae (down to 1860) and the analytical tables for 



their determination, which it contains. 

 2. Keue oder wenig bekannte Asiliden des K. Zool. Hofcabinets in 



Wien (Verb. Zool. Bot. Ges. 1867, p. 355—412). 

 Mr. van der Wulp published a paper, about the Asilidae of the 

 Eastern Archipelago. [Tijdschr. v. Ent. Vol. XV, 1872.] 



98. Gonypes nitidus. Macquart quotes Tab. XII, f. 7; the comparison 

 however of this figure with the descriptions of G. nitidus and G. Au- 

 douinii in the letterpress shows, that the figure refers to this latter 

 species. The name nitidus must be dropped, having been used before; 

 the name G. gigas, engraved on the plate instead of G. Audouinii, must 

 likewise be erased. The passage in Loew , Linn. Entom. II , p. 395, 

 proposing to adopt the name gigas for nitidus, was written before Mac- 

 quart's mistake in the quotation of the figure had been discovered. 

 Schiner did well in proposing a new name for the species. [Communi- 

 cated by Loew in litt.] Mr. van der Wulp makes the same correction 

 in Tijdschr. v. Entom. 1876, p. 172. 



99. Ceraturgus niger, of which I saw the type in the Jardin des 

 Plantes, looked like a Taradicus rather than a Ceraturgus. I have not 

 examined it closely, but have had occasion to examine a similar, per- 

 haps the same, species in the Berlin Museum, which is undoubtedly a 

 Taradicus. 



100. The Mus. Comp. Zool. possesses a number of specimens of 

 a Microstylum, which is of the same size as 31. morosnm, but which 

 Dr. Loew, to whom I communicated a specimen, considers a different 

 species, and calls M. pollens. It is less intensely black than morosnm, 

 antennae and legs are often reddish -brown, the bristles on the sides of 

 the thoracic dorsum are yellowish-white etc. As I had no opportunity 

 to make a thorough comparative study of both species, I merely draw 

 the attention of collectors to it. 



M. pollens, like M. morosum, was taken at Dallas, Texas, by Mr. Boll. 



101. Stenopogon ochraceus v. d. Wulp. The closed fourth posterior 

 cell makes this species a Scleropogon But if I understand Mr. v. d. 

 "VVulp's letterpress, the front tibiae are armed with a spur. How can 

 in this case the species be a Stenopogon? 



102. There is an Ardiilestes Selys, Odonata 1862. 



108. Dizonias bicinctus Loew. Loew describes the male. Speci- 

 mens often occur without any trace of the white abdominal crossbands; 

 they may however have disappeared since the death of the specimen. 

 The type of Dasypogon tristis Walker, which I have seen in the Brit. 

 Mus. is such a specimen. 



The female of this species differs very considerably from the male 

 and might easily be mistaken for a different species; I will therefore 

 mention here that head, antennae, and thoracic dorsum are reddish- 

 brown, and not black; the two abdominal crossbands yellow, and not 

 white; legs brownish-red, more or less blackened* on the femora; wings 

 brown; costal vein brownish-yellow. Both sexes were found flying tog-
