DYNASTIN/E 241 



jiilianus, the pygidium also similar, the hairs forming however a 

 single broadly aggregated line at some distance from the base; 

 metasternum wholly impunctate medially, even at the anterior 

 margin, punctured broadly antero-laterally as usual; legs very 

 stout, the anterior tibiae with more strongly developed teeth, the 

 uppermost small, however, as usual. Thoracic ridge lower than in 

 jiilianus. Length 47.0-48.0 mm.; width 23.0-25.0 mm. Colombia 

 to the Amazons. Two moderately developed males, taken at Para, 

 Brazil, by C. F. Baker *aloeus Linn. 



Hind tarsi much shorter, not as long as the tibiae, the legs rather less 

 stout 5 



5 Body stout, oblong-oval, shining, piceous-black, the elytra and under 

 surface much paler, castaneous-red; head nearly two-fifths as wide 

 as the prothorax, the tubercles rounded, very widely separated, the 

 clypeus not rugulose but with distinct and widely separated rounded 

 punctures throughout, becoming smaller and closer at the sides, the 

 middle mandibular tooth large, high and rounded; antennal club well 

 developed, much longer than the six preceding joints, 'its first jointonly 

 moderately angularly prominent on the lower face at the middle, the 

 anterior slope with dense erect hairs, which however are extremely 

 short; prothorax two-fifths wider than long, fully as wide as the elytra 

 and four-sevenths as long, the oblique sides toward apex broadly, 

 feebly sinuate; cavity very smooth and polished throughout and 

 without trace of a longitudinal ridge in about its posterior half; the 

 entire surface of the pronotum is devoid of any trace of rugulosity, 

 except the usual two transverse areas at base; posterior processes 

 not so broad as in julianus and with their apices more oblique, at an 

 angle of 45, the apical horn evenly reflexo-arcuate, more than twice 

 as long as the head, obliquely flattened at the sides and with the apex 

 feebly binodulose; scutellum nearly smooth in about apical half and 

 nearly to the base at the sides; elytra but very little longer than wide, 

 nearly as in julianus; pygidium of the usual form, convexity, basal 

 punctures and pubescence, without apical punctures in the type (cf ) ; 

 metasternum punctured and pubescent in less than anterior half, 

 though, as usual, nearly to the base at the sides. Female longer 

 but relatively less stout than the male, much larger than the female 

 of julianus, with evidently more elongate prothorax, having the 

 clypeus not simply punctate as in the male, but with separated 

 asperate rugulosity, the apex as usual more narrowly truncate than 

 in the male and with smaller and less elevated mandibular tooth. 

 Elytra more elongate than in julianus. Length (cf 9 ) 43.0-45.0 

 mm.; width 22.0-23.5 mm. Texas. A single fully developed male 

 from an unrecorded part of the state and two females, Named in 

 honor of Theodore Roosevelt roosevelti n. sp. 



Body stouter, the female smaller than in roosevelti, black, with dark cas- 

 taneous elytra to black throughout above, paler castaneous beneath, 

 polished ; head as in the preceding, and smooth at base except that the 

 sparse punctures of the clypeus are replaced by moderate rugulosity, 

 which is sometimes mingled with very minute sparse punctulation, the
