the apices of the joints but without producing a distinct annulation 

 as it does in pergrata; prothorax short, rather more than one-half 

 wider than long, the sides swollen and subprominent just behind the 

 middle, the two glabrous spots very clearly limited and distinctly 

 tumid; elytra parallel, wider than the prothorax, each very broadly, 

 evenly and semicircularly rounded at apex, the finer sutural and 

 marginal striae distinct; abdomen densely cinereo-pubescent, the 

 fifth segment in the type a third longer than the fourth, deeply 

 impressed in more than apical half, the impression transversely 

 elliptic; pygidium feebly, evenly convex, broadly arcuate at apex. 

 Length n.o mm.; width 3.2 mm. Kansas brevicollis n. sp. 



6 Body very elongate, narrow, only feebly convex above, black, the 

 head and entire prothorax pale testaceous; erect hairs short, pale, 

 a little longer toward base of the elytra; head not swollen, strongly, 

 the front closely, punctate; antennae (cf ) not quite as long as the 

 body, piceous, clothed with fine dark brown pubescence, largely 

 cinereous beneath; prothorax opaque, convex, slightly transverse, 

 with feebly and subevenly arcuate sides, the surface with very fine, 

 not dense cinereous pubescence, parted by three broad, more deeply 

 fulvous and glabrous entire vittae, the erect hairs rather long, pale; 

 elytra slightly wider than the prothorax, three and one-half times 

 as long as wide, coarsely, rather closely punctate, only a little less 

 finely apically, the punctures not at all concealed by the very short 

 fine luteo-cinereous appressed hairs, the exterior discal elevated line 

 moderately distinct; abdomen very minutely, sparsely punctulate, 

 minutely, not densely cinereo-pubescent and (c?) with the sides of 

 the last three segments broadly, densely sericeo-pubescent and 

 paler, yellowish, the fifth segment with a large and very deep oval 

 excavation; pygidium evenly rounded at apex. Length (d 71 ) 12.0 

 mm. ; width 2.8 mm. Texas ruficollis Horn 



Body similar but not quite so elongate, deep black, the head and pro- 

 thorax partly pale, the pubescence nearly as in ruficollis, the erect 

 hairs everywhere shorter, the antennae similar, three-fourths as long 

 as the body ( 9 ) ; head only very feebly swollen, the punctures coarse, 

 finer on the front, all well separated, the color testaceous, the sides 

 behind the eyes broadly, and a feeble median vitta, black; prothorax 

 opaque, a fourth wider than long, the sides broadly and feebly 

 swollen just behind the middle, the punctures coarse and close-set 

 laterally, sparser medially and subobsolete in the pale areas; color 

 testaceous, with a medial and broader juxta-coxal vitta black, and, 

 on the sides, a large black anterior and another basal, spot of black, 

 the latter dilated inwardly obliquely along the base and obsolete at 

 the middle, the pale vittae with a very small elongate area of fine 

 minute ashy pubescence, elsewhere nearly glabrous; elytra almost 

 as in the preceding but less coarsely and, toward tip, much more 

 finely punctate; abdomen (9) minutely, sparsely punctulate, very 

 minutely, inconspicuously fusco-puberulent and with numerous 

 palish coarse erect hairs throughout, the fifth segment two-thirds 

 longer than the fourth, feebly sinuato-truncate but not reflexed at 

 tip, the stria deep, extending nearly to the tip, the pygidium sharply
