Crabro (Cuphopterus Moraw. ) operus n. sp. 



9 . Length about 7 mm. Clypeus with the usual medial carina, 

 the anterior margin with four distinct, rather sharp teeth ; ocelli 

 in a triangle, the distance between the lateral ones about equal to 

 the distance from them to the nearest eye margin; first joint of 

 flagellum a little longer than the second; usual frontal depression 

 above antennae; a line-like furrow from frontal depression to lower 

 ocellus; a more indistinct one from lower ocellus to vertex; head 

 finely and densely punctured, more sparsely on occiput and cheeks ; 

 face sub-opaque, cheeks shining; pronotum with a rather strong 

 anterior ridge, dentate laterally ; dorsulum with very fine longitu- 

 dinal striae on posterior part, and sub-transverse striae on anterior 

 part ; among these striae are punctures and at first sight the dor- 

 sulum looks finely punctured ; a medial ridge for nearly the entire 

 length of dorsulum ; scutellum with large sparse punctures ; meso- 

 pleurae rather finely striate ; enclosure of metathorax obliquely striate, 

 a distinct longitudinal furrow down the middle; this furrow broadens 

 somewhat on posterior face and forms a fovea; posterior face of 

 metathorax with some transverse striae, stronger below; sides of 

 metathorax finely striated ; lateral ridges distinct ; ridge between 

 upper and posterior face not as strong as lateral ridges, more or 

 less indistinct ; a transverse furrow on basal half of some of the 

 abdominal segments above ; abdomen indistinctly punctured above ; 

 second ventral segment with a few large, shallow punctures; py- 

 gidium narrowed apically as in the sexmaculatus group, rather acute 

 at apex ; four posterior tibiae serrate beneath ; all the femora robust ; ' 

 tarsi single; first recurrent nervure in apical third of cell. Color 

 black ; spot on mandibles, scape behind, tubercles, spot on all the 

 tibiae beneath, a small elongate spot on sides of abdominal segments 2-5 

 yellow; tarsi, more especially the anterior pair, and teguloe reddisli ; 

 clypeus and lower inner orbits with silvery pubescence ; sides of 

 pygidium with long gray hairs ; rest of insect without hair. Wings 

 subhyaline, nervures and stigma dark brown. 



Habitat Beulah, N. M. ( W. P. Cockerell) . Two females. 



The striation of the dorsulum seems to run this species into 

 Fox's group singular is, but it is certainly not any species in 

 that group. Disregarding the striation of the pronotum, it 

 runs to paucimaculatus Pack., from which it may be separated
