384 MEMOIRS ON THE COLEOPTERA 



broad and rather feebly convex, black, sometimes piceous anteriorly, 

 the elytra very feebly iridescent; head relatively larger than in agilis, 

 with moderate but prominent eyes, two-thirds as wide as the pro- 

 thorax; antennae slender, fuscous, the three basal joints and palpi 

 pale, the labrum rufous; prothorax nearly a fourth wider than long, 

 the deeply sinuate apex a little narrower than the base and with 

 somewhat prominent though blunt angles; base margined except 

 medially, the angles moderately obtuse, with slightly blunt apex; 

 surface with scattered punctures medio-basally, very fine stria and 

 obsolete apical incised line, the latter visible laterally and sometimes 

 very faintly traceable medially; foveae deep, not quite attaining the 

 base; sides moderately, subevenly arcuate, narrowly reflexed and 

 diaphanous; elytra nearly one-half longer than wide, a third wider 

 than the prothorax, parallel, rapidly and obtusely rounded behind, 

 with distinct sinus and with posteriorly diaphanous margins, the 

 suture dull rufous posteriorly; striae rather fine and groove-like, 

 finely, rather obscurely punctate, the seventh gradually finer basally; 

 intervals but very moderately convex; sides beneath and abdomen 

 slightly rufous. Length (9) 6.2-6.35 mm.; width 2.25-2.4 mm. 



Texas (Galveston) taeniatus Lee. 



Femora rufous, the posterior however more obscure than the two anterior. 

 Body black and moderately convex, almost entirely black beneath; 

 elytra feebly iridescent; head elongate, with moderately prominent 

 eyes and distinct neck, three-fifths as wide as the prothorax; labrum 

 and mandibles rufous, the latter blackish at tip; antennae very slen- 

 der, piceous, the three basal joints and the palpi pale testaceous; 

 prothorax parallel, a fifth wider than long, the sides broadly, sub- 

 evenly arcuate, the margin narrowly reflexed, diaphanous posteriorly; 

 apex moderately sinuate, with very blunt angles and only very little 

 narrower than the base, which is margined only from the line of the 

 foveae outwardly, the angles obtuse and rounded; apical incised line 

 entire and broadly angulate, the stria very fine, incomplete as usual; 

 impressions obsolete; scattered subbasal punctures minute and very 

 few; foveae narrow, deep, not attaining the base; elytra rather more 

 than one-half longer than wide, fully a fourth wider than the pro- 

 thorax, gradually arcuately rounded behind from near the middle; 

 sides subevenly arcuate; suture feebly rufescent posteriorly; striae 

 not fine, rather deep, scarcely impressed, the punctures not coarse 

 but strong and crenulating the intervals, which are barely at all 

 convex; seventh stria fine, completely obsolete basally. Length ( 9 ) 

 6.5 mm.; width 2.4 mm. Florida (Dunedin), Blatchley.
