HAUCTUS (CHLORALICTUS) LIGUANENSIS, new species. 



Female. — About 5 mm. long; head and thorax ohve green; abdomen 

 black; pubescence rather short and dull white. Facial quadrangle 

 longer than broad; orbits converging slightly below; antennae entirely 

 dark, the flagellum hardly paler beneath; face very delicately punc- 

 tured, the punctures more scattered below and on the sides of the 

 face; lower half of clypeus shining black with a few punctures; upper 

 half of clypeus and supraclypeal area lineolate and sparsely punctured; 

 mandibles reddish. Mesothorax microscopically lineolate, delicately 

 punctured, the punctures more scattered on the disk; median and pa- 

 rapsidal grooves distinct, but not deeply impressed; sculpturing of 

 scutellum similar to that of the mesothorax, two polished spots on 

 the disk ; disk of propodeum without an inclosing rim, faintly tessellate 

 with a few plicae at the base of the area; truncation distinct later- 

 ally; tegulae reddish, impunctate. Abdomen obovate, shining, im- 

 punctate; segments clothed with rather scant pubescence. Wings 

 faintly dusky; anterior wing about 3.5 mm. long; stigma andnervures 

 dark testaceous; second submarginal cell higher than broad, receiv- 

 ing the first recurrent nervure near the apex; third submarginal a 

 little longer than second on marginal. Legs dark with yellowish 

 hairs; knees and tarsi somewhat reddened. 



Habitat. — Liguanea Plains, Jamaica, November-December 1911 

 (C. T. Brues). 



Type.—CU. No. 26404, U.S.N.M. 



Mrs. ElUs referred this specimen with doubt to jamaicae, but it 

 seems to be distinct. 



Differs: From jamaicae Ellis by the darker tegulae; disk of pro- 

 podeum not lineolate, and plicate at base only; scutellum with two 

 polished spots on disk ; face more sparsely punctured. 



From deceptor Ellis by the broader face; vertex with closer punc- 

 tures; legs not entirely dark; mesothorax more sparsely punctured. 



HALICTUS (CHLORALICTUS) ADMIRANDUS. new species. 



Female. — About 5-5.5 mm. long; head and thorax blue-green; 

 abdomen black; pubescence white, rather dense. Facial quadrangle 

 longer than broad; orbits converging below; antennae brown- 

 ferruginous, becoming ferruginous at the apex of the flagellum; face 

 covered with moderately close haii-s; front closely punctured, the 

 punctures more sparse on the sides of the face; supraclypeal area 

 and upper part of the clypeus blue-green, microscopically lineolate 

 and delicately punctured; lower half of clypeus shining black, with 

 few coarse punctures; mandibles faintly reddish. Thorax quite 

 densely pubescent; mesothorax dull, microscopically tessellate, with 

 quite close but shallow punctures; punctation of scutellum similar 

 to that of the mesothorax, two punctureless spots on the disk; disk
