punctures; scutellum smooth and almost impunctate ; apical depression 

 of first abdominal segment bounded above by a strong ridge, which is 

 concave toward the depression (in Foxii the depression is less conspicu- 

 ously bounded, and the boundary is straight) ; first r. n. entering second 

 s. m. a little beyond the beginning of its last third. Otherwise Foxii and 

 Melandri are about the same, but the difference of thoracic sculpture 

 makes the latter a very easily-separated species.

Sphecodes Colujubice^ n. sp. 



9. — Length about 11 mm., of anterior wing just over 7 mm., width 

 of abdomen about 2-/1 mm.; head and thorax black, abdomen long, 

 entirely bright yellowish-ferruginous ; legs black, only the small joints of 

 tarsi dark reddish ; wings strongly brownish in the region of the cells ; 

 flagellum stout, the apical half obscure reddish beneath ; third antennal 

 joint longer than fourth, and somewhat longer than broad 3 labrum 

 broad, not ernarginate, nor much produced ; mandibles stout and blunt, 

 wholly without an inner tooth ; clypeus with very large partially-confluent 

 punctures. This was taken, at first sight, for S, Kincaidii, but it is not 

 that species. With the large size and simple and dark mandibles of 

 Drepanittm, it combines the ordinary labrum of Sphecodes, etc. It agrees 

 with the description of S. Kiucaidii except as follows : Size smaller ; face 

 with scanty dull white pubescence, but also coarse black bristles ; 

 antennae not wholly dark ; first joint of flagellum not so short ; mandibles 

 simple ; mesothorax with large strong punctures on a shining ground 

 posteriorly, but rugose anteriorly ; tegula? with hyaline margins ; stigma 

 ordinary, not especially large ; hind tarsi not all red ; second abdominal 

 segment with small close punctures basally ; third punctured like the 

 second, except that the area of small close punctures is larger. The first 

 segment, and the second and third except basally, have scattered strong 

 punctures on a very shiny ground ; apex with dark hair; apical plate small 

 and narrow ; second submarginal cell very narrow, much higher than 

 broad, receiving the first r. n. near the beginning of its last third ; area of 

 metathorax hemispherical in outline, regularly cancellate, with a very 

 sharp and definite rim. By reason of the area of metathorax, the smooth 

 sparsely-punctured base of abdomen, etc., one is reminded of S. 

 arroyanus^ which, however, differs from S. Cohimbice by the shorter area of
