Some Carpenter Bees (Hym.). 

 By T. D. A. COCKERELL, Boulder, Colorado. 



The Xylocopine bees listed below were received from the 

 Queensland Museum. Two prove to be undescribed ; the types 

 are in my collection. The others mostly represent new locali- 

 ties. 



Xylocopa valga Gerst. Ras-el-Ma, Algeria, 9. (Queensl. Mus. 39.). 

 Alfken records X. ralga from two localities in Algeria. 



Xylocopa amedaei Lepel. Ras-el-Ma, Algeria, 9. (Queensl. Mus. 

 40.). Originally described from Algeria. 



Xylocopa brasilianorum (L.) "Guyane, Maroni." 9. About 

 21 mm. long, wings not quite so dark as usual (Queensl. Mus. 13.) 



Xylocopa medionitens sp. n. 



9 . Length about 22.5 mm., anterior wing 17 mm., width of abdomen 

 nearly 9.5 mm. ; black, with black pubescence, but that on thorax above 

 fox-red, leaving a shining median area extending to anterior margin 

 of mesothorax, its anterior portion with black hair; head 7 mm. wide, 

 tubercles of labrum ordinary; clypeus with large and coarse, not dense, 

 punctures ; upper part of clypeus bounded by a shining swollen rim, 

 which has a small tubercular projection in middle; hair of head entirely 

 black; extreme end of scape, and second antennal joint, largely red; 

 third joint little longer than next two together; flagellum greyish- 

 brown beneath except at base ; pleura black-haired ; tegulse black ; wings 

 reddish-fuliginous, subtranslucent, the apical field darker, iridescence 

 pale golden, the apical region coppery ; venation normal ; legs black- 

 haired, hind tibiae with a smooth shining space on outer side ; abdomen 

 shining, black-haired, well punctured, with a rather indistinct median 

 keel above and a distinct one below. 



Hab -"Guyane, Maroni" C Queensl. Mus. 7). From En- 

 derlein's short description, this might be X. rufidorsum Ended., 

 from Peru ; but the wings appear to be lighter and differ- 

 ently colored, and the very difficult locality would suggest a 

 distinct form. Enderlein says that his insect, except for size, 

 recalls the African X. uii.rta; but X. medionitens does not 

 suggest mi.vta. Among the African species it resembles X. 

 carinatci fulropilosa Friese. In Schrottky's table the ne\v 

 species falls nearest to X. auntlcnta (Fab.), to which it is evi- 

 dently allied, but the size is quite different, and Lepeletier 

 says the sides of the thorax are red-haired in aitntlcnlu.
