ART. 4 NORTH AMERICAN WEEVILS BUCHANAN 13 



MESAGROICUS STRIGISQUAMOSUS, new species 



One female specimen. Length, 5.4 mm.; width, 2.3 mm. Moder- 

 ately robust, scales coppery, paler as usual along sides of pronotum, 

 upper margin of eyes, and on undersurface. Setae white. Rostral 

 groove shallow basally, deeper in apical half, surface each side densely 

 and roughly punctured; head densely punctured; eyes subcircular, 

 rather prominent. Scape about as in hispidus; first funicular segment 

 much stouter than second, and nearly twice as long, seventh more than 

 twice as broad as long. Prothoracic proportions as in hispidus; 

 pronotal sculpture consisting of punctate and very feebly elevated 

 remnants of granules which coalesce in places, giving the surface a 

 subrugose and irregular, roughly punctate appearance. Normally, 

 this sculpture would be obscured by the coating of large, rounded, 

 distinctly striate scales. Elytral setae in an irregular single row along 

 each interval, those on fifth interval considerably confused; serial 

 punctures small, largely concealed by the scales. Fifth ventral of 

 female with a well-defined impression. 



Type locality. — Altamont, Calif. (C. M. Packard, collector.) 



Type.— C&t. No. 41753, U.S.N. M. 



MESAGROICUS OCULARIS, new species 



One female specimen. Length, 3.9 mm.; width, L8 mm. Body 

 robust, less convex than usual, scales brownish coppery, paler around 

 eyes and on undersurface. Head and rostrum, except apical %, 

 densely, subconfluently punctate, the latter area with small, unevenly 

 spaced punctures; rostrum lightly concave and with a fine median 

 sulcus. Eyes subcircular. Scape setose, not squamose, in apical 

 half; first funicular segment much stouter and twice as long as second, 

 seventh strongly transverse. Prothorax transverse (5 to 4) sides 

 feebly rounded in basal %, more strongly so toward apex, which is 

 distinctly narrower than base; dorsum flattened for a short distance 

 behind apical margin, pronotum with punctate and setigerous gran- 

 ules, and normally with a coating of rounded, contiguous, striate 

 scales. Elytra deeply emarginate at base, intervals broad and flat; 

 scales large, 3 or 4 together bridging an interval, closely appressed, 

 varying from slightly separated to slightly overlapping, nearly 

 obliterating in places the rows of rather small punctures; setae long, 

 finer and more numerous than usual, in a confused row along each 

 interval. Apical half of last ventral segment with a broad, transverse 

 impression; first and second segments broadly and feebly concave. 

 Undersurface densely and finely punctate.
