palpi not or hardly pubescent ; tlie broad an J Hat vertex, the 

 rnesotliorax, and scutellum with thin black hair; tegulai 

 very dark brown. Wings dusky. Legs black, spurs very 

 pale ; middle tarsi greatly broadened ; hind basitarsus very 

 large and flat, much longer than the remaining joints to- 

 gether, and with light yellow hair on its inner side. Abdomen 

 with very short black hair between the bands ; last segment 

 with erect hair only at sides. 



Very closely allied to the Mexican M. chrysophila, Ckll., 

 but differing in tlie colour of the ventral scopa, the propor- 

 tionately longer hind basitarsus, the shape of tlie mandibles, 

 &c. 



Hah. Keatchie, Louisiana, July 8, 1905, two specimens 

 {Wilinon Neivell). 



Meyachile niuriiiella, sp. n. 



? . — Length about 10 mm. 



Black, broad, the abdomen long-cordiform ; pubescence 

 greyish white, scanty, becoming mouse-grey on sides of 

 metathorax ; abdominal bands well developed, but hardly 

 noticeable because dull mouse-grey, the last and the sides of 

 the penultiniate scantily overlapped by shining white hairs ; 

 ventral scopa dull white, black on last segment except at 

 extreme base, and some black hair at sides of penultimate ; 

 claws with a sharp basal tooth ; no light hair-markings on 

 thorax above. Ilead ordinary, rather large, eyes distinctly 

 converging below; clypeus shining, with strong, rather close 

 punctures, its apical margin straight ; mandibles 4-dentate, 

 with golden hairs projecting from the lower margin ; an- 

 tennaj dark ; mesothorax densely punctured ; tcgulte dark 

 rufous. Wings moderately dusky ; recurrent nervures 

 joining second submarginal cell at equal distances from apex 

 and base. Legs black, hair on inner side of tarsi pale 

 yellowish ; spurs whitish ; hind basitarsus only moderately 

 large. Abdomen between the bands with a pale hardly 

 noticeable pruinosity ; some black hairs, not readily observed, 

 on the last two segments, particularly the penultimate one. 



I had formerly supjjosed, from a superticial examination, 

 that the grey abdominal bands were accidentally discoloured; 

 but this seems not to be the case. The species is related to 

 M. cleomis^ Ckll., but much smaller.
