160 ' THE CANADIAN ENTOMOLOGIST, 



brown. Wings fuliginous, nervures and stigma piceous, a pale dot at base 

 of stigma. A small hyaline spot at angle between marginal and second 

 submarginal cell, and one just beyond upper corner of third discoidal. 

 Venation practically as in cethiops, but the marginal cell not so narrow in 

 proportion to its length. Legs black, knees and external bases (half, more 

 or less) of tibi:x' pale yellow, tarsi pale yellow, the terminal joints becom- 

 ing brown. Claws only slightly bifid. Abdomen densely punctured, the 

 apical margins of the segments smooth and constricted. $ . — Length about 

 7 mm., more robust, abdomen broader, segments not constricted, punctua- 

 tion in general finer, legs with dirty white hairs, dense on hind pair. Legs 

 dark, with a light yellow spot at extreme base of each of the anterior and 

 middle tibiae. Face wholly dark. 



Habitat. — New Mexico; the 9 o^^ Bigelovia IVrightii, at Las 

 Cruces, Sept. 23rd, 1895 ; the $ at Albuquerque, middle of August, 1895. 



This species is a sort of small brother of C. cethiops (Cr.), from which 

 it is easily distinguished not only by its size, but by the sculpturing of the 

 metathorax. C. cethiops, 2i\?,o, does not have the shining boss at the 

 summit of the eyes, which is present in both sexes oifraterculus. I have 

 taken C. cethiops at LasCruces, N.M., Sept. 2 1,1895, *^" Helianthus anjiuus. 



Calliopsis perlcbvis, n. sp., % . — Length, 8 mm., black, shining ; face 

 and thorax without pale markings. Head subquadrate, not particularly 

 large, a little longer than broad ; clypeus rather prominent, produced into 

 a tooth on each side ; mandibles dark reddish at ends ; face, clypeus, 

 front, vertex and cheeks strongly punctured, the punctures smallest and 

 most dense on front and beneath antennae ; antennae reaching as far as 

 base of wings, joints 6 to 10 of flageilum testaceous beneath. Mesothorax 

 shining, with small shallow punctures, fairly dense in front and at sides, 

 but becoming sparse towards the middle, and almost lacking in the middle. 

 Scutellum with sparse punctures, base of metathorax longitudinally 

 wrinkled. Pubescence of head and thorax sparse, very pale brownish, 

 most noticeable on cheeks, occiput and pleura ; only a few scattered hairs 

 on sides of metathorax. Tegulae amber colour. Wings subhyaline, 

 grayish, yellowish towards the base, costal nervure and stigma dark brown. 

 The outermost nervures also dark brown, but the rest amber colour. 

 Second submarginal a little shorter than first, narrowed about half to 

 marginal. Legs dark, a rather ill-defined small yellow spot at base of 

 each of the four anterior tibite, tarsi becoming rufescent. Hind legs with 

 a copious clothing of hair. x\bdomen shining, parallel-sided, the apical
