Macquart, as early as 1838, detected that Cuban specimens 

 were specifically distinct from the Mallophora scopifer de- 

 scribed by Wiedemann from Brazil, but he failed to propose 

 a new name for the species. This was done by Rondani, who, 

 twelve years later, proposed the name macquartii for the 

 Cuban form. After a lapse of thirteen years Rondani pro- 

 posed another name, scopipcda, for the same form, evidently 

 having forgotten his previous action. Osten Sacken had the 

 name macquartii from Loew and was under the impression 

 that it was a manuscript name ; hence we find scopipcda given 

 priority in the Aldrich catalog. 



Malloplwra macquartii, thus far, is known only from Cuba. 

 There are before me two females and a male, all taken at 

 Cayamas by Mr. E. A. Schwarz. The species may be best 

 compared with the North American Mallophora orcina of 

 Wiedemann. It agrees with this in the yellow-haired head, 

 scutellum and anterior margin of the thorax ; as in that species 

 the abdomen is dorsally yellow-haired, black at tip, the fifth 

 to seventh segments being black-haired. The Cuban species 

 differs by the absence of black bristles from the mystax ; 

 the femora and tibice are ferruginous instead of black, and 

 are pale yellowish-haired, only the apices of the tibise black- 

 haired ; the venter on the first four segments shows a medium 

 line of rather loose, long, erect yellowish hairs, while in 

 orcina the venter is wholly densely black -haired. In the male 

 macquartii the front tarsi are dorsally whitish haired, while 

 in the female they are all black. Mallophora orcina shows 

 an entirely different sexual dichroism. In the female all the 

 legs are wholly black-haired, while in the male the hind tibiae 

 are white-haired over a considerable portion of the lower sur-
