412 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. x.xxi. 



Length. — 20 mm., male. 



Form yleiuler, also the legs and antennse. — ^ 



Black. Fore and middle legs in part rust red; hairs of "the head and thorax yel- 

 low; almost no pubescent spots are noticeable; wings strongly fuliginous with l)lue- 

 violet reflection. 



Clypeus s(]uarely cut off in front; inner borders' of the eyes slightly converging 

 toward the clypeus; nearest distance of the eyes at the vertex e(iual to the length of 

 the first and half of the second filament segments; scutellum arched as usual. 



Dorsum of the median segment finely transversely aciculate; petiole relatively 

 long, as long as the second segment of tlie very elongated hind foot, also as long as 

 the pedicel and first filament segment together; ventral plates of the fifth, sixth, and 

 seventh segments without close, long hairs or pubescence; form of the ventral plate 

 of the eighth segment; Plate XII, fig. 101. 



Cameron has sent me the male but not the female to examine. Therefore I give 

 here the description of that author: 



Nigra, femoribus tibiisque anticis rufis, capite, pro et mesonoto dense aureo-villosis, 

 metonoto dense albo-villoso; alls violaceis $ $. 



Long, 30 mm. 



Habitat. — Mexico, Temax, in north Yucatan (Gaumer); Guatemala, Pantaleon, 

 1,700 feet (Champion). 



On the head the golden pile is very dense, except on the center of the clypeus, and 

 on the vertex and occiput (perhaps rubbed off); the pronotum in front is bare, and 

 the center of the mesonotum also. Eyes parallel, but very slightly converging at the 

 top. Clypeus with some large punctin-es, the apex rounded, the furrow wide and 

 deep; basal half of the mandibles reddish, aciculated. Mesonotum slightly 

 depressed toward the apex in the center, as is also the pronotum; metanotum opaque, 

 coarsely transversely aciculate, densely covered with a soft, white, woolly pubes- 

 cence, and slightly depressed in the center toward the apex. Petiole as long as the 

 hind coxse, sparsely covered with long, white hair. Apex of the abdomen slightly 

 punctured and sparsely covered with long hair. 



The statement as to the length of the species, 30 mm., appears to be an error, as 

 the male type sent measures only 20 mm. 



Ill .some regards this description is suggestive of Chlorioii mandihi- 

 lar')x Cresson.

I have seen no specimens of this species, and am therefore obliged 

 to give here a translation of the description given by Kohl: 



Length. — 20-25 mm., female. 



Body black. Legs wholly black or more or less red. In the example described 

 by Saussure the entire femora, tibife, and tarsi are rust red; in other examples in the 

 Vienna Natural History Museum dark pitchy red spots show on the four anterior 

 legs; Cameron's type has the legs entirely black. Wings pale, with a weak yellow 

 reflection.
