500 FAMILY III. CURCULIONID.E. 



stria? on basal half very deeply, coarsely and confluently punctate, becom- 

 ing narrow toward apex; intervals irregularly alternate in width and con- 

 vexity. Front and middle tibiae with the outer angle feebly prolonged. 

 Third joint of front and middle tarsi strongly dilated; of the posterior 

 tarsi, feebly so. Length 7.5 mm. 



Described from Pennsylvania, Illinois, Iowa, Colorado and 

 Texas. "In the sand hills of Reno County, Kansas, which in dry 

 seasons become intensely hot to the destruction of insect life, 

 many dead specimens were found May 1, having apparently lit in 

 swarms on the sand and been overcome by the heat before they 

 could rise in flight, as many of them had their wings still pro- 

 truded." (Knaus.) Resembles zcw in form and general appear- 

 ance. 



875 (8990). SPHENOPHOKUS CARIOSUS Oliv., 1807, 91. 



Elongate-oval. Black, the elevated portions above and under surface 

 shining. Beak three-fourths as long as thorax, strongly compressed along 

 median portion, sparsely and finely punctate, more coarsely at base. Thorax 

 about as broad as long, sides subparallel, male, feebly converging, female, 

 from base to near the distinctly constricted apex; disc with three vittse, 

 the median beginning at apical constriction, dilated to a rhomboid near 

 middle, then either ending abruptly or prolonged in a fine line toward 

 base; outer ones broad, sinuous, entire, the lateral branch short, broad; 

 vittaa minutely and sparsely punctate; their intervals and sides of disc 

 coarsely punctate, covered with a thin dark gray coating, the sides with 

 a small, smooth, coarsely punctate area behind the apical angle. Elytra 

 at humeri slightly wider than thorax, then feebly curved and converging 

 to apex; striae fine, their punctures coarse, deep, distant; intervals flat, 

 each with a single row of minute punctures; third strongly elevated on 

 basal half, its elevated portion, the humeral callus and a small one near 

 declivity, smooth, shining. Length 8 11 mm.

 6. Recorded from New England and Canada to Illinois, south to 

 Florida, but many of the records are based on wrong determina- 

 tions and refer to collosus Oliv., which LeConte and Horn erro- 

 neously united with cariosus. The latter species occurs very 

 rarely in the Northern States, and Horn was probably about cor- 

 rect when he gave its distribution as ''Middle States, rarely; 

 Gulf States, abundantly." Chittenden, who showed that callosns 

 and cariosus were distinct, concluded that Uhler's sculpt His is a 

 synonym of cariosus, and that the species usually known and 

 figured as sculptilis is in reality sew Walsh. The above descrip- 

 tion of cariosus is from Florida specimens. As Horn well said 

 before callosns was united with it, "it is one of the most easily
