entirely dark ; tegulse black, with black hair. Wings dusky, 

 nervures dark fuscous. 



In the tables in Trans. Amer. Eut. Soc. 1906, this runs to 

 group L (p. 86), and falls in the vicinity of M. communis, 

 Cress., from which it may be known by the yellowish abdo- 

 minal bauds, the lack of any distinct light band at base of 

 second segment, and the black hair on clypeus. In the table 

 on p. 113 of the work cited it runs near to M. wickhami and 

 communis. It is easily separated from wickhami by the 

 abdominal segments not having hyaline margins, and the 

 colour of hair oi clypeus and anterior and middle legs. It 

 is very much like M. simil/ima, Rob., but may be distin- 

 guished by the fourth abdominal segment having the whole 

 margin covered with light hair, the band on third segment 

 broad and not oblique, and the colour of hair on hind basi- 

 tarsus. 



Hab. Mexico ; 2 ? in Berlin Museum. 



The labels bear the following rather ambiguous informa- 

 tion :— " Ciudad, Mexico, Californien, 8000', Forror S." I 

 suppose that Mexico City or the vicinity is intended. Speci- 

 mens of M. tepaneca, Cresson, bear labels with the same data. 



Xenoglossodes excurrens, Ckll., 1903. 



I have a female which I took at Las Cruces, New M<xic 

 Sept. 23, at flowers of Isocoma wrightii. It is in very got 

 condition, and shows that the hind part of the Kiesothor? 

 and the disk of the scutellum have some short black ha 

 this also can be seen in the original type on close inspectic 

 A noticeable character is seen in the nude area on first abdo- 

 minal segment, which is narrow in the middle and broadly 

 lobate on each side, giving an outline Lke two caps of liberty 

 joined front to front. In the type specimen this is not clear, 

 some of the hair having been worn away. 



Melissodes pecoselia verbesiiurum, (J,;ll., is a synonym of

Noviia bolliana, sp. n. 



? . — Black, looking at first sight exactly like A 7 , triangu- 

 lifera, Vachal, and collecting orange pollen in exactly the 

 same way, but differing as follows: — Less robust, the thorax 

 especially smaller; anterior wing a little over [) mm. (fully 

 10 in ti iangulifera) ; wings redder ; nervures and stigma clear 

 light ferruginous ; rugose basal area of metathorax smaller, 

 in the form of a regular very slender crescent ; posterior face
