Genus Xijlocopa. 297 



ascertain whether the species has been described, I have 

 adopted the name, believing it to be a manuscript one. 



• 116. Xylocnpa micans.

This species is readily distinguished ; the female is of a 

 dark blue-black, the abdomen usually having a violet or 

 purple tint ; the pubescence is black, except a thin fringe 

 on the thorax posteriorly of griseous pubescence; a tuft of 

 white on each side of the basal segment of the abdomen, 

 and another on each side of the apical segments ; between 

 these the fringe is black ; the wings subhyaline, with their 

 apex clovided. Length seven to eight lines. 



The male is of a nigro-a3neous colour, the abdomen 

 partaking of vivid tints of violet and blue in certain lights ; 

 the labrum, clypeus, the face on each side, and the scape 

 of the antennae in front, yellowish-Avhite. The pubescence 

 on the thorax, basal segment of the abdomen, anterior 

 tibise and tarsi, and the outside of the femora, rufo-ful- 

 vous ; the intermediate tarsi are densely fringed with 

 black pubescence, the first joint having a patch of white. 

 The eyes large and approximating on the vertex. The 

 abdomen testaceous beneath. Having had an opportunity 

 of seeing the types of the sexes, I have united them as 

 constituting one species.

The " morio " of Fabricius is undoubtedly one of the 

 large species of the genus, the original description in the 

 " Entomologia Systematica" gives " Magna, tota atra," 

 and remarks on its close affinity to A', latipes. Cresson, I 

 believe, is in error in referring tliis small species to the 

 Fabrician one. 



The male of X. cuhcccola is fulvous, with the labrum, 

 clypeus, and antennae beneath, pale yellow ; between the 

 antennse, on the vertex posteriorly, and on the thorax, the 

 pubescence is ftilvous ; at the base of the abdomen it is
