THE CANADIAN ENTOMOLOGIST 299 



rather close punctures ; penultimate ventral segment minutely roughenedl 

 with dense punctures of two sizes ; apical plates much as in lucrosa, but- 

 the dorsal plate has the narrowing nearer the base, and its keel is dis- 

 tinct ; the ventral plate appears to be rather more produced. Close ta 

 lucrosa and masta, but probably a distinct species. 

 Coelioxys Giiensis, Ckll., 1898. 



Length: o, 9-10 mm.; ?, 11 mm. The discovery of the female 

 shows that this s.pecies is very close to C. inodesta, Smith, but differs in 

 the colour of the legs and the entire abdominal bands. $ . Gallinas 

 River at La Cueva, at flowers of Psaralea tenuiflora^ August 6 (Ckll.) ; 

 Rio Ruidoso, at flowers of Vicia a.^. pulchella, about 6,700 feet, July 29 

 (Townsend). ^ . Rio Ruidoso, with the % s just cited, also at flowers- 

 of Rhus glabra, about 6,500 feet, July 19 (Townsend) ; Gila River 

 (Townsend) ; Santa Fe, July 6 (Ckll.). The males resemble rnfitarsis, 

 but are uniformly smaller. 

 Coelioxys Apacheorum., n. sp. 



Mescalero, July 20 (C. M. Barber). $ . Somewhat related to C. 

 alternata, Say, as interpreted by Cresson. Length 11 mm., narrow, with 

 the shape of C. Giiensis; pubescence dull white ; face quite densely 

 pubescent ; anterior border of mesothorax with the band of pubescence 

 divided behind into three teeth, the lateral ones the most distinct; scutellum 

 with hind edge strongly convex, without a central nodule ; lateral teeth 

 long and almost straight ; antennae and mandibles black ; legs black, 

 including tarsi ; spurs dark ferruginous ; punctures of mesothorax and 

 scutellum large and deep ; wings strongly suffused with brown ; nerv- 

 ures black, stigma ferruginous ; tegulse ferruginous, piccous at base ;. 

 abdomen shining dorsally, with strong but sparse punctures ; abdominal 

 bands regular and entire ; additional bands of hair at the sides of the 

 segments, marking the transverse depressions, which, however, entirely 

 fail broadly in the middle of the dorsum ; ventral surface strongly and 

 rather closely punctured, the penultimate segment with small punctures 

 interspersed between the large ones; apical dorsal segment ending in a 

 point at an angle of perhaps 80', the longitudinal keel wanting, or 

 slightly indicated at the tip ; apical ventral segment not greatly produced 

 beyond the dorsal, rounded, its margins hairy. 



This species is peculiar for the absence of a keel or raised line on 

 the last dorsal segment, and the broad interruption of the transverse 

 grooves on segments 2 and 3. Using these characters, our species of 

 Coelioxys separate thus :
