collected in Madeira and Tenerife. 213 



shining, with quite microscopic rugulosities on the basal segment as 

 in genalis, face short, cheeks linear, orbital furrows much produced 

 posteriorly, slightly curved at their termination near the base of the 

 posterior ocelli, propodeal area smoother than in the ^ , the reticu- 

 lations almost obsolete except at the base, basal segment of abdomen 

 with a distinct very narrow line of snowy-white pubescence ; 

 calcaria pale. 

 Long. 5 mm. 



Orotava, visiting Franlcenia, $ 3, 21. iii. 02. 



Laguna, Tenerife, $ 1. 2 or 3 kilom from the city upon 

 the ridge to the left of the Tejina road. Altitude 2100 — 

 2500 feet. 



Sauzal, $ 1. Altitude about 900 feet.

This pair is named quadristrigahcs in the collection, 

 but neither $ nor $ is I think referable to that species, 

 and in this opinion Mens. Vachal agrees ; whether they 

 are $ and $ of one species is also doubtful; the $ has the 

 clypeus entirely black ; the $ is in such bad condition that 

 it is impossible to be sure of its identity, and I hesitate to 

 describe a new species on a single ^. 



Halictus, sp. ? 



$ 3. Laguna, 15. iii. 02, 



Closely allied to, if not a variety of R. scaliosm, Rossi, 

 but without knowing the other sex, I am afraid to deter- 

 mine it for certain, as there are already several closely 

 allied forms described in the group whose specific value 

 is very doubtful; BruUe (Webb-Berthelot, Hist. Can. ii, 

 p. 87) records scahiosie as occurring in the islands, but 

 remarks that he has only seen one $ , which differs from 

 scahios/B in having the antennaj beneath entirely yellow ; 

 this makes me suspect that Brulle's ^ and these $ s may 

 belong to a distinct Canary Island species. 



Halictus, sp. (?). 



$ Madeira. T. V. W. 



In Wollaston's collection there is a single $ under the 

 name zehrus, Walck., but it is in such a condition as to 

 render identification practically impossible.
