278 MEMOIRS ON THE COLEOPTERA 



suture is seldom apparent; striae fine, coarse and close as usual at 

 apex, the scutellar rather long; intervals flat or very feebly convex, 

 the discal puncture rather before apical fourth; hind tarsi and male 

 sexual characters nearly as in anceps. Length (d 71 9) 5.0-5.8 mm.; 

 \vidth 1.9-2.2 mm. Utah (Provo). Seven examples. 



peregrinus n. sp. 



Form and size nearly as in dissimilis but of different color and with the 

 thoracic foveae less marked, shining, nigro-piceous; prothorax 

 slightly shorter than wide, narrowed posteriorly, with the sides 

 rounded; all the angles rounded, the entire periphery testaceous; 

 surface rugose at base, punctulate latero-basally but scarcely foveate; 

 elytra shining, cyanescent, the lateral limb testaceous; striae deep, 

 posteriorly excavated, the second unipunctate; middle of the sterna, 

 legs, mouth-parts and antennae flavo-testaceous, the antennae fuscous 

 distally; male with the anterior tarsi broadly, the intermediate 

 slightly, dilated. Length 6.2 mm. Colorado River, near the Gila. 

 A single male cincticollis Lee. 



20 Form oblong, very moderately convex, shining, rufous, the head 

 black; pronotum clear rufous, the elytra similar in color, but with a 

 large elongate black spot on the suture, the latter not pale or but 

 very feebly pallescent; under surface and legs clear rufous, the meta- 

 sternum and its parapleura nigrescent; head well developed, three- 

 fourths as wide as the prothorax, the eyes very prominent; antennae 

 long, very slender and filiform, dark brown, the two basal joints pale; 

 prothorax a third wider than long, widest before the middle, the 

 sides rounded, rather less so basally; apex feebly sinuate, with obtuse 

 angles and fully as wide as the base or somewhat wider, the base 

 transverse medially, with very broadly rounded angles; surface 

 unusually finely, evenly reflexed at the sides, the foveae isolated, 

 rounded, extremely feeble and with numerous distinct punctures, 

 finely extending to the sides as a rule; stria very fine; elytra one-half 

 longer than wide, a third wider than the prothorax, parallel, with 

 feebly arcuate sides and evenly, subcircularly rounded apex, the sinus 

 obsolete or barely traceable; striae strong, impressed, the scutellar 

 moderately long, parallel; intervals evidently convex, the discal 

 puncture just before apical fourth; hind tarsi shorter than usual, 

 two-thirds as long as the tibiae, the first joint not as long as the fifth ; 

 male with the anterior tarsi feebly dilated, the intermediate very 

 slender. Length (cf 9 ) 4.8-6.0 mm.; width 1.8-2.2 mm. Missis- 

 sippi, Louisiana and Texas (Austin). Abundant dissimilis Dej. 



Form oblong, feebly convex, larger and stouter than the preceding, with 

 relatively smaller head, the coloration nearly similar throughout, 

 the metasternum less dark, the elytral black area more nearly 

 attaining the base and with a very feeble opalescent lustre, the suture 

 finely rufescent; head black, pallescent at apex, three-fifths as wide 

 as the prothorax, the mandibles pale, black at tip; eyes similar; 

 antennae slender and filiform, feebly fusco-testaceous, clearer basally; 

 prothorax as in dissimilis but more transverse, two-fifths wider 

 than long, the sides rather more strongly rounded, the basal angles 

 scarcely so broadly as in that species; apex similarly very feebly
