HARPALIN^E 285 



basally, gradually finely acuminate and slightly arcuate distally. 

 The fourth joint of the maxillary palpi is less than one-half longer 

 than the third; it is rapidly finely subulate at tip. The last seg- 

 ment of the abdomen in the female is very broadly, subevenly and 

 circularly rounded and bears the usual four long setse near the 

 apical margin. 



Agonoleptus is evidently one of the connective bonds between 

 Stenolophus and Agonoderus, possessing some suggestive characters 

 of each, although on the whole closer to the former. The single 

 known species is as follows: 



Narrowly subparallel, subdepressed, shining, pale and very uniform 

 testaceous in color throughout the body above and beneath, the 

 head and legs also pale; head actually small but relatively moderate, 

 three-fifths as wide as the prothorax, the eyes very convex and 

 prominent; antennae very slender, filiform, more than half as long 

 as the body; prothorax but little more than a fourth wider than long, 

 widest before the middle, the sides rather strongly rounded, gradu- 

 ally less so and converging basally, the apex feebly sinuate, with 

 rather blunt angles and much wider than the base, the basal angles 

 broadly rounded; surface very smooth, wholly impunctate, extremely 

 finely reflexed at the sides, the median stria very fine but distinct 

 and entire, the foveae represented by small punctiform impressions 

 at a considerable distance from the base; elytra more than one-half 

 longer than wide, barely a fourth wider than the prothorax, parallel, 

 with feebly arcuate sides and abruptly broadly and very obtusely 

 rounded apex, the sinus completely wanting and not even traceable; 

 striae feebly impressed, the scutellar very short, oblique; intervals 

 feebly convex, the discal puncture between apical fourth and fifth; 

 legs short, the hind tarsi with the first joint as long as the next two 

 combined but not quite as long as the fifth. Length ( 9 ) 4.0-4.5 mm. ; 

 width 1.2-1.35 mm. Colorado (Colorado Springs 6100 feet), 

 Wickham parviceps n. sp. 



There seems to be some community of structure and facies be- 

 tween this species and Stenolophus unicolor, and possibly the latter 

 might with propriety be removed from Stenolophus and placed in 

 the present genus, although the emargination of the mentum is 

 there much larger and more rounded and the surface behind it 

 flat, with the usual two erect setse, this surface being concave and 

 apparently without setae, except perhaps one or two at the sides of 

 the mentum, in Agonoleptus. The marginal edge of the notch, 

 also, is not doubled in unicolor and the scutellar stria is long and 

 parallel, the hind tarsi with a longer basal joint. The peripheral
