longiceps, while the colors and markings disagree with cupriventris. 

 In Schrottky's later table (Zeits. Hym. Dipt., 1907, p. 480) this 

 runs to C. gossypii Schrottky, which really seems to be closely 

 allied, but in gossypii the pleura is finely punctured, the scutellum 

 is blue-green, and there are various other differences. Compari- 

 son with other recent descriptions does not indicate identity in 

 any case. 



Ceratina manni sp. nov. 



Female. Length about 4^ mm.; dark but shining bluish-green, the apical half 

 of the abdomen roughened; sides of front hardly punctured; a large broad elongate 

 (vertical) mark on clypeus, a small broad-oval mark on each side of it, a broad elon- 

 gate mark (like that on clypeus, but smaller) along each anterior orbit opposite 

 antennae, and a stripe on each cheek (receding from orbit) all ivory-white; mandi- 

 bles and labrum dark, the labrum and apical half of mandibles obscureh' reddish; 

 antennae black basally, the thick flagellum light ferruginous below, dark rufopi- 

 ceous above; tubercles broadly white margined; tegulae dark reddish; wings dusky. 

 The mouthparts are not greatly elongated. Tarsi dusky reddish; anterior tibiae 

 with a pale stripe. (In C. lucidida the legs are pale testaceous.) 



Hah. — Independencia, Parahyba, Brazil, 6 females {Mann & 

 Heath). This little species resembles C. nautlana Ckll., but is at 

 once distinguished by the five light marks on face. It also resem- 

 bles, on account of its small size, C. hicidula Sm., Tnnelleri Friese, 

 gossypii Schrottky, and minima Friese, but it will not agree with 

 any of them. Ducke says that muelleri is the same as lucidida, 

 but the legs are quite differently colored. C. minima is known only 

 in the male, but I am confident that manni is not its female. 



Melipona pseudocentris sp. nov. 



Worker. Length about 11 5 mm.; head and thorax with pale fulvous pubescence, 

 bright orange-fulvous in middle of pleura; clypeus light ferruginous, the upper 

 border infuscated, a median stripe and the lateral comers cream-colored; a cres- 

 centic cream-colored supraclypeal mark, bordered above by ferruginous; cream- 

 colored lateral face-marks broad below, narrowing above, ending above level of 

 middle of front; scape red; third antennal joint conspicuously red beneath; abdo- 

 men bright chestnut red, with coarse black hair in apical region, but tuft at ex- 

 treme apex ferruginous; legs red and black. Extremely close to M. rufiventris 

 Lep., from which it differs in its larger size and considerably darker abdomen. The 

 legs are marked exactly as in rufiventris, and the face markings essentially agree. 



Hah. — Manaos, Brazil {Mann & Baker). I should have con- 

 sidered this a local race, or perhaps individual variety, of M. riifi-
