1912] Cockerell — New Bees from Brazil 57 



Hab. — Natal, Brazil {W. M. Man?i). Probably a distinct 

 species, but agreeing so nearly with the description of D. para- 

 guayensis that I leave it for the present as a subspecies. 



Tapinotaspis heathi n. sp. 



Male. Length about 85 mm., anterior wing nearly 8; shining black, the supra- 

 clypeal region, front and abdomen very brilliant; pubescence mainly black, but 

 dense and shining creamy-white on clypeus and sides of face, long silvery hairs 

 project below mandibles, the anterior half of pleura has long plumose white hair, 

 anterior legs with white hair on outer side, hair on inner side of hind tibiae dull 

 white, and on inner side of their tarsi pale ferruginous; fourth abdominal segment 

 with a tuft of white hair on each side, fifth and sixth with white hair at sides, and 

 dorsally in the subapical region with glittering, pale, partly metallic hairs; under 

 side of abdomen with black hair-bands; hair of thorax above, and the very abundant 

 hair of middle legs, all black; malar space obsolete; supraclypeal area smooth and 

 impunctuate; antennse long and slender, scape black, flagellum ferruginous, pale 

 beneath, the first joint largely dark, the last three joints on inner side, and a square 

 patch on apical part of the one before, shining snoio-ichite ; mesothorax microscopically 

 sculptured; anterior wings dark fuliginous, the apical field very large, nervures fus- 

 cous, stigma rather large, reddish; b. n. meeting t. m.; marginal cell obtusely pointed 

 at apex, away from costa; first and second submarginals about equal, third larger; 

 second quadrate, narrowed about a third above, receiving first r. n. almost at its 

 apex; third s. m. broader above than second, receiving second r. n. a little beyond 

 beginning of its last third; lower wings hyaline, darkened on costa and broadly 

 so at apex, anal lobe very well developed; hind basitarsus nearly as long as tibia, 

 produced at end into a thumb-like lobe which is largely red; first three abdominal 

 segments without apical hair, except at sides; fourth with a short purplish-black 

 fringe, fifth and sixth with heavy black fringes; apical plate broadly truncate. The 

 elongate two basal joints of labial palpi are subequal. 



Hah. — Independencia, Parahyba, Brazil {Mann & Heath), 

 This may perhaps have been described as a Tetrapedia from the 

 female, but if so, there is no way to ascertain the fact. It looks 

 like Tetrapedia diversipes Klug, except for the smaller size and the 

 color of the hair on the hind legs. The venation is however entirely 

 different from that of T. diversipes, and also very different from 

 Exomalopsis, to which genus I next thought to refer it. The 

 reference to Tapinotaspis is unsatisfactory, because the second 

 submarginal cell is not at all as in that genus, but it is possible that 

 the definition of Tapinotaspis may be altered to include such forms 

 as the present. Tapinotaspis is considered by Brethes a synonym 

 of Tetrapedia, while a species was described by Friese as an Exo- 

 malopsis. It is probably a valid genus, or at any rate, the species
