segments broadly dark reddish brown ; yellow markings on 

 abdomen as follows : on first segment a pair of very lar»c 

 pyiiform patches, pointing mesad, and not reaching sub- 

 dorsal region, on third to sixth a broad entire band ; apical 

 segment broadly rounded, black with a submarginal yellow 

 band, outside of which the margin is translucent; die 

 seventh segment subcarinate, shining, with large Bparse 

 punctures. 



?. — Similar to the male, exeept as follows: mandibles 

 entirely black; clypeus black, except the narrowly yellow 

 upper lateral margins; a yellow dot on supraclypeal area; 

 lateral i'ace-niarks ending obtusely above, and below squarelv 

 truncate at about level of upper end of clypeus; femora 

 without a yellow mark behind ; ventral scopa white.

 lection, 10. 



Very similar to B \ flavom a rginatum , but the face-markings 

 of the male are quite different, and there is no pit on the 

 seventh abdominal segments. This does seem to a^ree 

 quite perfectly with Priese's too brief account of his Anthi- 

 dium flavomarffinatum, var. ecuadorium, but his specimens 

 were taken by the same collector at the same place and are 

 doubtless conspecitic. 



Dianthidium macrurum, sp. n. 



S • — Length 15 mm. or rather more, if the abdomen were 

 held straight ; anterior wing 1(H mm. 



Red and yellow, with little black; head and thorax 

 extremely densely punctured above, the mesothorax. dull, 

 but the pleura with larger, separated (though close) punc- 

 tures, the surface between them shining; hair of head and 

 thorax fulvous dorsally, paler beneath, pale around the very 

 strongly keeled tubercles : vertex, checks, and sides of front 

 rather narrowly ferruginous ; front except sides black, this 

 enclosing ocelli ; area between antennae red, but a black band 

 below antennae, but the lower part of the supraclypeal area 

 red; clypeus and sides of face yellow, the upper half of the 

 clypeus suffusedly reddened ; mandibles yellow with the 

 apex and cutting-edge black, only two well-formed teeth ; 

 labium black ; antennae red, with the apical half or more of 

 flagellum black ; thorax red, the scutellum very bright, a 

 good deal of black in region between metathorax and meso- 

 pleura, and metathorax narrowly black at sides of base ; 

 tegulse large, red, closely and finely punctured. Wings dark 

 reddish fuliginous; second r. n. going well b. second
