486 Mr. T. D. A. Cockerell — Descriptions and 



Halictus leichardti, Cockerell. 



The type of H. leichardti is abraded ; H. paracolletinus, 

 Ckll., described from fresb specimens, is the same species. 

 I arrived iat this conclusion after the types had been returned 

 to the British Museum, but Messrs. Meade-Waldo and 

 Turner have kindly compared tlie types, and have no doubt 

 that the names refer to a single species. 



Megachile liguanensis, sp. n. 



$ . — Length about 9 mm. 



Black, with white pubescence (a slight admixture of dark 

 hairs on vertex and scutellum) ; legs bright ferruginous, 

 hair on inner side of tarsi orange-ferruginous, very bright 

 bn hind basitarsi ; ventral scopa white, entirely black on 

 last two segments ; clypeus densely punctured, with a 

 smooth shining median stripe, the lower margin feebly 

 denticulate; mandibles quadridentate ; flagellum beneath 

 dark rufo-f uscous ; vertex dull, densely and minutely punc- 

 tured ; mesothorax and scutellum sculptured like vertex ; 

 no anterior hair-spots on mesothorax, but a very conspicuous 

 tuft of white hair on each side above the hind end of tegula ; 

 a rather feeble hair-band in scutello-mesothoracic suture, 

 but long white hair behind scutellum . Wings slightly dusky, 

 especially in costal region ; stigma dull ferruginous, nervures 

 fuscous. Abdomen shovel-shaped, but not of the very broad 

 type, shining, with narrow and weak white hair-bands ;

Hab. Liguanea Plain, Jamaica, Nov.-Dec. 1911 {Mrs. C. 

 T. Brues). 



From the same locality Mr. Brues sent also M. lanata 

 (Fabr.), and M. poeyi, Guer. In Friese's table of West 

 Indian Megachile, this runs to M. deceptrix, Smith, a larger 

 and otherwise different insect, the type of which I have 

 examined. It may also be compared with M. poeyi, which 

 is larger and has yellow abdominal bands. [ have not been 

 able to find any species from North or South America which 

 it closely resembles. 



Megachile huascari, sp. n. 



? . — Length about or almost 13 mm. 



Robust, broad, black, with black hair, mixed with dull 



white on face around antennae ; ventral scopa light orange, 



last segment with scanty black hairs ; clypeus shining but 



closely punctured, with no median smooth line, its anterior
