46 Psyche [April 



rupted in middle; legs reddish, blackish and yellow, the anterior femora and tibise 

 broadly striped with yellow; tegulse deep ferruginous, with an orange spot; mar- 

 ginal cell and apical part of wing dark fuliginous; abdomen black, with very broad 

 oblique orange bands, widely separated in middle, on first segment, on second a nar- 

 rowly pear-shaped yellow mark on each extreme side, on third a narrow yellow band 

 on each side ending mesad in a v'ery large elongate club, on fourth to sixth entire 

 bands, that on sixth notched in front; seventh segment cream-color, the lateral cor- 

 ners with long straight spines, the truncate ends of which are dark, while in the mid- 

 dle is a very slight prominence. So close to D. gregarium {Hypanthidium gregarium 

 Schrottky) that I had considered it identical, until I noted the antennse, which is 

 heathi are long but quite normal, the flagellum slender but not crenulate, dark above, 

 ferruginous below, whereas in gregarium the flagellum is very long, strongly crenu- 

 late below, each joint light ferruginous with the base black, but the last entirely 

 black; the armature of the apex of the abdomen is quite the same in both. These 

 forms have pulvilli, and represent an aberrant section of Dianthidium. 



Hah. — Independencia, Parahyba, Brazil (type locality), 3 males 

 {Mann and Heath); Natal, Brazil, one male {W. M. Mann). The 

 D. gregarium compared is from Villa Encarnacion, Paraguay, col- 

 lected by Schrottky. An apparently allied species is Anthidium 

 pygmoeum Friese, known only in the female. Judging from 

 Friese's description, our species is too different from fygmceum 

 to be its male. 



Ceratina chrysocephala sp. nov. 



Female. Length about 9h mm.; head and thorax very strongly and coarsely 

 punctured, golden-green, the head with golden tints, the mesothorax with crimson, 

 the posterior disc of mesothorax with a smooth dark area; pubescence very scanty, 

 thin and white on pleura and sides of meta thorax; mandibles and labrmn entirely 

 black; clypeus dull in the middle, and with large punctures, the lower margin with 

 a very broad transverse orange band, not reaching lateral corners; lateral face- 

 marks orange bands, very broad below, rather irregular on inner side, ending above 

 at about level of antennae; posterior orbits with broad orange bands, the upper 

 part leaving the orbit; antennse red as far as fourth or fifth joint, dark piceous or black 

 beyond; scutellum closely punctured, roughly granular posteriorly; tubercles 

 green; tegulse dark chestnut; wings deep fuliginous, with violet tints; legs more 

 or less green; anterior tibise with a yellow stripe, cormecting with a spot at apex of 

 femur; middle tibise with a yellow basal spot, hind tibise ferruginous at base; hind 

 tibise with much white hair; middle femora conspicuously angled beneath toward 

 base; abdomen shining dark bluish-green, with slight brassy tints, strongly punc- 

 tured; sixth ventral segment subcarinate. 



Hab. — Manaos, Brazil {Mann & Baker). In Schrottky 's table 

 of Brazilian species this runs to the vicinity of C. longiceps Sm. 

 and cupriventris Sm. The shape of the head is not at all as in
