finely and somewhat remotely punctured, the intervals as wide as two or three of 

 the actual punctures ; 2nd segment more finely and closely punctured ; punctura- 

 tion of the following segments less close and vaguer ; 7th ventral segment and 

 armature resembling those of phalericus, Morice (Trans. Ent. Soc. Lond., 1904, pi. 

 vii, figs. 17, 17«), the former having its lobes short and rounded at the apex, the 

 latter having the wing-like appendages of the sagittse produced far beyond the 

 solid part of these organs and terminating in a rather sharp angle at their external 

 apex. 



? . Very like the ^ only wider, and with the ordinary ? characteristics ; la- 

 brum very shining, with a small central fovea, elypeus very largely punctured, the 

 punctures tending to become confluent, and to form longitudinal striaB towards the 

 apex, which has two well-defined small foveoe near the centre filled with pubescence. 

 Abdomen less hairy than in the <? , the long hairs of the 1st segment only covering 

 its base, and the erect hairs on the other segments scarcely observable, except on 

 the 4th and 5th ; 5th segment without a white pubescent band, but with its apical 

 margin widely pale, like the preceding. Ijong., 8 — 9 mm.

Closely allied to phalericus, Mor., and coriandri, Perez., but quite distinct from 

 the first by its elongate cheeks, and from the second by the much less pilose abdo- 

 men, the paler hairs of the thorax, &c.

 Echitim and Sherardia arvensis, L. 



1 ? . Santa Cruz, alt. 1000 — 800, 9.iv.04, visiting Sapistrttm rugosum, L. 



14. Sphecodes, sp. ?. 



4 9 • Forest of La Mina, alt. 2700—2800, 7 and 9.iv.04, entering burrows in 

 goat tracks. 



Tills species is so like S. dimidiatus that I should prefer to see the i before 

 treating it as distinct. 



15. Halictus vibidis, Brulle. 5 ? , Puerto Orotava, in the Barranco Martianez, 



11 and 12.iii.04 ; 4 $ , Giiimar, on annual species of Euphorhia, 22 and 

 24.iii.04- ; 1 (J , 1 9 , Santa Cruz, visiting Bapistrum rugosum, 4.iv.04. 



The $ which Mr. Eaton captured in the same locality and on the same plant 

 as the 9 at Santa Cruz seems to me to be undoubtedly referable to this species. As 

 it does not appear to be described, I give a short diagnosis of it. 



Dark cyaneous, apex of the elypeus flavous ; antennae, from the 3rd joint, 

 testaceous beneath ; legs entirely black ; apical depressions of the abdominal seg- 

 ments bright blue, beneath black ; face clothed with white hairs anteriorly, with 

 fulvous-grey on the vertex and above the antennce. Head and thorax dull, very closely 

 punctured, face much produced in front, with distinct cheeks between the eyes and 

 mandibles, elypeus pentagonal, nearly as long as wide, its base just above the level 

 of the apices of the eyes. Antennse with the 4th joint about as long as the 2nd 

 and 3rd together, and not quite so long as the scape, the rest about half as long 

 again as wide, becoming more swollen towards the apex, so that the antennae 

 are very slightly clavate. Head behind the eyes contracted towards the thorax.
