? . — Length 9-lOJ mm. 



Black, with white hair and entire white abdominal bands : 

 vertex and disc of mesothorax, and scutellum more or less, 

 Avith dark fuscous hair ; ventral scopa mainly bright ferru- 

 ginous, but broadly white basally, and black on apical part

 band down the middle (wanting in jjahnarum) ; the meso- 

 thorax has short pale appressed hair anteriorly and poste- 

 riorly ; the tegulse are more or less reddish, at least on 

 margin ; the ventral scopa is white basally ; and there is 

 black hair at sides of abdominal segments 4 to 6. 



^ . — Length about 8 mm. 



Like pahnarum, biit very easily separated by the apical 

 transverse keel of abdomen (sixth segment), which is slightly 

 depressed in middle, with about five little sharp teeth 

 (broadly, deeply, semicircularly incised in pahnarum). 

 Tegulse rather light reddish; mesothorax with appressed 

 ochraceous hair, broadly in front, narrowly behind ; middle 

 of third and fourth ventral segments of abdomen each with 

 a marginal patch of orange-fulvous hair, quite separate from 

 the Avhite hair-bands.
