long seen from in front, closely pnnctured, 

 the punctures very fine and close on the face. 

 Mandibles black, or so dark brown as to 

 seem so. Pubescence short, and inconspic- 

 uous except on front, sordid silvery. A 

 tubercle on %'ertex. Occiput simply punctate. 

 Antennae with fiagellum becoming dark red- 

 dish-brown. Thorax closely punctured ; pro- 

 thorax with two elongate niark.s on superior 

 margin, and the tubercles, white; mesotho- 

 rax with the anterior portion dull red, the 

 red extending about as far backwaids as tlie 

 level of the tegulae in the median line, but 

 laterally narrowly beyond the tegulae; on 

 the red portion with a weak meduin carina. 

 Scutellum and postscutellum each with a 

 median carina, that on the former rather 

 weak. Squamae yellowish-white, with the 

 external margins semi-transparent and radi- 

 ately wrinkled, the terminal points stout and 

 gently curved. Spine quite small, concave 

 above, rapidly narrowed to an acute point, the 

 sides straight. Metathorax above strongly, 

 subreticulatelv, obliquely ridged; median 

 area triangular, closed above, microscopi- 

 cally roughened within but shining and 

 crossed by three or four weak transverse 

 striae, acutely angled below, passing into a 

 rather short median carina ; lateral faces 

 striato-punctate, the striae subobsolete below, 

 strong above. Tegulae shining orange- 

 brown, with an opaque whitish spot on 

 anterior half. Wings hyaline, nervures 

 piceous, marginal cell bluntly pointed, the 

 apex directed away from the costal margin. 

 Legs black, spurs dark brown ; middle femora 

 with a white spot at tip beneath ; middle and 

 posterior tibiae with a short white streak at 

 base above, anterior tibiae with a ver}' narrow 

 white stripe extending about two-thirds of the 

 length from the base but sometimes obsolete. 

 Abdomen witli interrupted cream-colored 

 bands on segments 1-4; on the first segment 

 the band is reduced to two transversely elon- 

 gate patches, somewhat further apart than the 

 transverse diameter of either; puncturing 

 ■ coarse and sparse on discs of segments, fine 

 .and close about margins. Pygidium rufous. 



//««.— Santa Fe, N. M., July 6, 1S95, on 

 a white flowered Umbellifer (Ckll., 3353). 

 The specimen had previously visited an 

 Asclepiad, as shown by the pollen masse-- 

 adherent to the legs. Another example 

 from Fort Collins, Colorado (Baker) differs 

 in that the spine is longer, the points of the 

 squamae more produced, and the puncturing 

 coarser. Another from Las Cruces, N. M. 

 (C. Rhodes, 149). 



Oxybelus heterolepis, n. sp. — Male : About 

 7 mm. long, closely but rather coarseh 

 punctured, black with yellow maikings. 

 Head about as broad as long seen from in 

 front, strongly punctured, front and faco 

 covered with silvery pile. A slight protu- 

 berance on the vertex, but no well defined 

 tubercle. Mandibles pale yellow except the 

 dark tips. Antennae with the terminal half 

 of the fiagellum becoming rufous. Thorax 

 without any red, closely punctured. Pro- 

 thorax entirely black, except the pale yellow- 

 tubercles, in the middle of which is a dark 

 (really hyaline) spot. Cheeks, pleurae and 

 tubercles with short silvery pubescence : 

 vertex and thorax above with short black 

 pubescence. Scutellum and post-scutellum 

 each with a median carina, that on the lattei 

 somewhat prominent throughout its length. 

 Squamae with long slightly curved terminal 

 points, semitransparent, yellowish white, 

 separated by a distance as great as the base 

 of either. Spine moderately elongate, nar- 

 row, practically straight, parallel sided, 

 grooved above, brownish, with the tip 

 rounded and entire. Metathorax reticulate 

 above; median area short, smooth within, 

 open above, rounded below and passing into 

 a long median carina; lateral faces striato- 

 punctate. Tegulae and extreme base of 

 wings rufous, the former with an obscure 

 whitish spot. Wings hyaline, nervures 

 dark brown, marginal cell obliquely truncate. 

 Legs black, with the apices of all the femora 

 reddish yellow, the tibiae yellow externally, 

 and the tarsi yellow becoming rufescent at 

 ends. The yellow of the middle tibiae is 

 at about its middle half interrupted by a
