111 my table iu ' Psyche/ October 1905, this runs to C. tex- 

 ana, Cresson, which, however, has the middle and liind tarsi 

 black, and differs in other ways. The shape of the last 

 dorsal segment resembles that of C. comstockii, Cress., but 

 there is a slight median nodule in the middle of the apical 

 truncation ; in other characters the insect is quite unlike 

 comstockii. In Schrottky's table of Brazilian species it 

 runs to C. ignava, Sm., which has a quite different apex of 

 abdomen. 



Xenoglossa assimilis (Smith). 



Quirigua, Guatemala; two males at flowers of Ipomoea 

 sidcefulia, Choisy, Feb. 12 and 20 {W. P. Cockerell). 



Tliis is Melissodes assimilis, Smith ; it is a Xenoglossa 

 related to X. pridnosa, Say. The maxillary palpi are five- 

 jointed, the fifth joint very short. 



Agapostemon proscriptus J sp. n. 



$ . — Bright green, with the size and general appearance 

 of A. radiatus, Say, but differing as follows : — Base of meta-

 basal bands of white hair on abdominal segments 2 to 4 

 more conspicuous ; knees (broadly), tibite, and tarsi ferru- 

 ginous ; hair on inner side of hind tarsi orange-fulvous ; 

 second s.m. very broad, broader than high. The mandibles 

 are light yellow basally and rufous apically ; the labrum is 

 dark reddish. 



Hab. Guatemala City, Guatemala, two {tV. P. Cockerell). 



Beseinbles the little-known A. pulcher, Smith, but the 

 wings are distinctly dusky (somewhat yellowish), and the 

 femora are black except at apex. Both specimens have 

 gathered bright orange pollen. 



Me.gacMle ze.nnenice, sp. n. 



$ . — Length about 12 mm. 



Black, rather long and parallel-sided, general appearance 

 much like M. lenticula, Vachal ; head broad ; eyes purplish ; 

 clypeus short and broad, closely punctured, with a rudi- 

 mentary median ridge, the lower margin gently concave, with 

 a median tubercle ; mandibles broad, black, the two apical 

 teeth distinct, the long inner cutting-edge without distinct 

 teeth ; supraclypeal area shining, convex, with scattered 

 distinct punctures ; hair of face creamy white, mixed with 

 black, long black hairs from each side directed toward
