ART. 18. BEES [N THE NATIONAL MUSEUM- — COCKERELL, 11 



ANDRENA NIPPONICA, new name. 



Andi'ena japonica Alfken, not of Smith. For its characters, in 

 relation to the other Japanese species, see Annals and Magazine of 

 Natural History for February, 1913 (p. 190). 



MEGACHILE STRUPIGERA, new Dpccies. 



Ferncde. — Length 12mm.; black, slender, parallel-si<led, very 

 coarsely punctured, ventral scopa with thickened straplike hairs; 

 clypeus densely rugose, without a smooth line ; face and front covered 

 with short red hair; cheeks with very large punctures, and a promi- 

 nent longitudinal keel posteriorly; antennae entirely black; vertex 

 with scant}^ red hair; mesothorax and scutellum very densely and 

 coarsely punctured, with short inconspicuous dark hairs; prothorax 

 and tubercles, and a small tuft beneath wings, with bright ferrugi- 

 nous hair; pleura and metathorax with thin white hair ; base of meta- 

 thorax with a narrow transverse channel, crossed by small ridges; 

 tegulae deep red, black basally; wings hyaline at base, beyond that 

 dark fuliginous, splendidly purple-iridescent ; legs black, with scanty 

 whitish hair ; spurs black ; abdomen shining black, not metallic, with 

 large punctures ; first four segments with transversely elongated lat- 

 eral white hair-patches; fifth with a very narrow white marginal 

 band, interrui:)ted in middle ; ventral scopa white, black on last seg- 

 ment and apex of penultimate. 



Canton, China (C. W. Howard). 



Type.—Cid. No. 24884, U.S.N.M. 



Closely allied to BI. thoradca Smith, from Java, but easily sepa- 

 rated by the red hair of face and front. 



MEGACHILE LATICEPS Smith. 



Meade- Waldo in 1914 published the opinion that M. caecina 

 Cameron, M. hojmeana Cameron, and M. varideiis Cameron, all from 

 Sarawak, were identical with the Philippine Island M. laticeps. On 

 examining the types in the British Museum, I found that this was 

 not the case. M. laticeps has white hair bands at sides of abdominal 

 segments 2 to 4, but fulvous on the first. M. varidens has bright 

 fulvous on 1 to 3, and no evident band on 4. M. varidens has a dull 

 very densely punctured scutellum, but laticeps has it more shining, 

 the punctures not so dense. M. laticeps has a broader face and vertex. 



M. caecina has red hair on face and thorax; scutellum shining 

 anteriorly. It is in bad condition, but is not varidens. M. horneana 

 is also different; it has much black hair on thorax above, white at 

 sides and posteriorly ; face and front with pale fulvous hair ; apex of 

 male abdomen (keel of sixth segment) broadly rounded and emar- 

 ainate.
