9 , with an apical fringe of wliite hairs at the sides, tliosc on the 3rd almost meet- 

 ing. Head and thorax dull, largely and rugosely punctured, clothed with greyish- 

 white hairs. Antennae stout, joints of Ihe flagellum wider than long, scutellum 

 rounded posteriorly, angularly produced on each side, the angles scarcely acute, 

 wings slightly dusky, postscutcllum bearing a short tubercular tooth ; propodeum 

 longitudinally rugose at the base. Abdomen rather shining, largely punctured, 

 clothed besides the bands with exceedingly short, almost imperceptible, greyish 

 hairs, these are rather longer on the apical segments, dorsal valve largely rounded 

 in both sexes, beneath punctured. Legs with the calcaria piceous, those of the 

 front legs paler, rather curved, their edges flattened, and more or less membranous, 

 emarginate at the apex. Long., 6 — 6^ mm.

23. Megachile canariensis, Perez. S ? . Giiimar, 22.iii.04. 



This is the species I recorded in my last paper as apicalis, $ , the velvety spot 

 on the 3rd abdominal segment is variable, as of two males taken in the same spot 

 one has it distinctly, the other has no trace of it. 



24. CHAliicODOMA CANESCENS, Brulle. <? ? , Puerto, Orotava, in the Rarranco 



Martianez, ll.iii.04. "The Mason Bees here plaster their nesta here and 

 there against the face of the lava cliffs sparingly." 3 ^ , Giiimar, 22.iii.04.

Cuesta, 800—1000 ft. alt., 4.iv.04 ; 2 S, Cruz de Afur, 3100—3250 ft., 



5.iv.0i ; 2 (? , Forest de la Mina, 2700—2800 ft., 7.iv.04. 



All the specimens sent, as well as the 2 c? from " Laguna, lfi.iii.02," quoted 



in my former paper (Trans. Ent. Soc. Lond., 1003, p. 216), are peculiar in the dark, 



almost black coloration. In the (J there is scarcely any metallic tinge observable, 



except on the abdomen, which might be described as bronzy-black, or in one case as 



blue-black, in the ? the abdomen is blue-black, and the head and thorax have a 



very slight bronzy tinge ; the puncturation of the mcsonotum also appears to me to 



be slightly closer, but these differences do not apjiear to indicate more than an 



insular variety of the species.
