1880.1 l^T [Horn. 



arcuate. Elytra oblong, parallel or with the sides feebly arcuate, surface 

 striate, intervals smooth and flat, a dorsal puncture in the usual position. 

 The bod}^ beneath is smooth. Legs and antennte rufous. Length .36 — 

 .40 inch ; 9— 10 mm. 



The ?7?aZe has the anterior tarsi dilated, the first joint much less so than 

 the others and without pubescence beneath, the three following joints are 

 normally pubescent ; middle tai'si less dilated, first joint glabrous, next 

 three pubescent. In the female the first joint of the anterior tarsus is 

 rather broadly dilated and thickened, slightly prolonged under the second 

 joint, not pubescent beneath, joints 2 — 5 slender ; middle tarsi slender. 



The resemblance of this species to Harpalus amputatiis is worthy of men- 

 tion, they are almost uudistinguishable by superficial comparison. It is 

 remarkable also that the first joint of the anterior tarsus of the male should 

 be so feebly dilated and that of the female so much so. 



Occurs in the Gulf States. 



9. A. dulcicoUis Ferte. Form somewhat oval, black, shining, legs 

 piceous. Thorax broader at base than apex and as wide as the elytra, sides 

 moderately arcuate, hind angles obtuse, basal impressions moderate and 

 with very few punctures. Elytra oval, sides moderately arcuate, surface 

 striate, intervals smooth, slightly convex, dorsal puncture distinct. Body 

 beneath smooth, shining. Length .44 inch ; 11 mm. 



The anterior tarsus of the male is normally dilated, the first joint pubes- 

 cent beneath, the middle tarsi nearly as broadly dilated, the first joint pu- 

 bescent at tip. 



In the female the tarsi are slender, the first joint of the anterior is how- 

 ever somewhat stouter than in rusticus. The elytra are less shining than 

 in the male. 



Occurs in the Gulf States and Missouri. 



10. A. opaculus Lee. Elongate oval, subparallel, black, opaque. 

 Thorax not wider at base than apex, sides feebly arcuate, hind angles ob- 

 tuse, basal impressions feeble, surface impunctate. Elytra oblong, sides 

 feebly arcuate, surface finely striate, intervals flat, at apex 3 — 5 — 7 with a 

 few feebly impressed punctures, dorsal punctures normal. Body beneath 

 smooth, shining, legs piceous. Length .44 inch ; 11 mm. 



The male sexual characters are as in dulcicolUs. Tlie characters of the 

 female are also similar but the first joint of the anterior tarsus is a little 

 stouter but much less so than in liarpaloides. 



Having seen a typical specimen oi elongatus Q\\?iU.ci., I have no hesita- 

 tion in placing it with the present species, the ditferences given by that 

 author are certainly more of an individual character than of a specific 

 nature. 



Occurs in Texas. 



11. A. rusticus Say. With this species I unite not only those already 

 suppressed by Dr. LeConte (List p. 12) but also merula Germ, and liaplo- 

 mus Chaud. The accumulation of large numbers of specimens shows
