Records of Bees, 485 



cj . Similar to the female, except as follows : ground- 

 colour of head and thorax black, not red ; labrum pale 

 reddish ; clyp6us and supraclypeal area bright yellow, and 

 the bright yellow lateral face-marks wholly filling space 

 between clypeus and eye ; yellow band along posterior orbits 

 variable, either extending along whole length of orbit or 

 broken in middle ; basal part of first abdominal segment 

 black ; apical plate of abdomen broad, truncate, not 

 emarginate. 



Hab. Liguanea Plain, Jamaica, Nov.-Dec. 1911, three of 

 each sex (C T. Bruts). One was collected by Mrs. Brties. 

 The type is a female. 



The genus is new to Jamaica, and the species is closely 

 related to the various Micronomadce inhabiting the western 

 United States. From the species of Cuba, Haiti, and Porto 

 Rico it is readily known by the red head and thorax of the 

 female. By the red legs, it resembles N. krugii, Cress., from 

 Porto Rico rather than N. cubensis, Cress., from Cuba. 



Halictiis {Chloralictus) bruesi, sp. n. 

 ^ . — Length about or nearly 5 mm. 



Entirely pale brownish testaceous, including antennae and 

 legs ; clypeus prominent; face with fine white hair; eyes 

 moderately emarginate within ; antennae long, the flagellum 

 thick. Wings clear, iridescent, the stigma and nervures 

 sepia ; head and thorax dullish, abdomen shining ; thorax 

 with thin white hair. 



The following characters are microscopic : front finely 

 and very densely and evenly punctured ; mesothorax micro- 

 scopically tessellate, with rather widely separated very 

 distinct punctures ; area of metathorax with about twenty 

 fine but distinct more or less wavy ridges ; punctures of 

 abdomen very fine, becoming moderately dense toward 

 bases of segments, absent on apices of segments, which are 

 transversely striatulate ; first r. n. joining second s.m. a 

 little before the beginning of its last fourth ; outer nervures 

 scarcely at all weakened. 



Hab. Liguanea Plain, Jamaica, Nov^-Dec. 1911, 1 ^ 

 (C. T. Brues). 



Easily known by its singular coloration, which made me 

 think at first that it might be immature or diseased ; but 

 it is perfectly formed in every way, and doubtless normal. 

 Many species of Halictus are more or less testaceous, 

 or have the abdomen orange or brownish. The present 

 insect is perhaps nearest to the Brazil an H. nanus (Smith), 

 which, howevef, has the head and thorax yellowish green.
