DYNASTIN/E 149 



rather closely punctured anteriorly, sparsely basally, with a large 

 transverse occipital area wholly devoid of sculpture; eyes large and 

 very convex, separated by a little less than twice their width; 

 clypeus rufous, more transverse than in the preceding but of the 

 same general form and sculpture, the suture generally distinct 

 throughout and broadly sinuate medially, but sometimes transverse 

 and scarcely at all sinuate; antennal club long and curved as usual; 

 prothorax almost twice as wide as long, of the usual form, the punc- 

 tures laterad notably strong and rather close-set; scutellum very 

 acute at apex, strongly punctate, with smooth margins; elytra a 

 third or fourth longer than wide, the punctures rather small, moder- 

 ately impressed, with evident geminate series but very variable 

 in strength, sometimes conspicuous, occasionally almost obsolete; 

 marginal bead finely punctate and with short erect stiff hairs; 

 pygidium almost bald; hind tarsi long, nearly two-thirds longer than 

 the tibiae. Female nearly like the male but with the elytra rather 

 more deeply and distinctly sculptured and the sides a little more 

 arcuate, the punctures along the marginal bead smaller, more widely 

 spaced and with still smaller erect hairs; hind tarsi slightly longer 

 than the tibiae. Length (14 d\ 6 9 ) 11.0-13.2 mm.; width 6.0-7.0 

 mm. Southern Arizona (in the Sta. Rita and Huachuca Mts., Doug- 

 las and at other places) arizonica n. sp. 



Body (cf) more or less stout in form, smaller, oblong-oval, rather shining r 

 pale brownish-flavate in color, immaculate and glabrous; head! 

 infuscate, rather closely punctate anteriorly, remotely and finely 

 basally, with a transverse impunctate occipital area; eyes moderate,, 

 separated by much more than twice their width; clypeus trapezoidal, 

 with rounded sides, angles and apex, the edges moderately reflexed; 

 surface densely punctate, generally somewhat impressed antero- 

 laterad, the suture usually complete and feebly sinuate; antennae 

 as usual; prothorax four-fifths wider than long, of the usual form and 

 sparse, laterally more evident, punctuation; scutellum pointed, 

 sparsely punctate, with smooth borders; elytra short, a fourth or 

 fifth longer than wide, but slightly wider than the prothorax, broadly 

 and obtusely rounded at tip, the sculpture of the usual order, the 

 punctures rather small, feeble and well separated as a rule; pygidium 

 with a few very short erect hairs basally; hind tarsi rather less than 

 one-half longer than the tibiae. Female somewhat more elongate 

 than the male, the other differences as usual, the clypeus shorter and 

 more transverse, the hind tarsi a little longer than the tibiae. Length 

 (17 d\ 12 9 ) 9.0-12.7 mm.; width 4.5-6.7 mm. (Valley of the Rio 

 Grande, from Jemez Springs and Albuquerque, New Mexico, to the 



great bend, Texas, Wenzel) melina n. sp. 



A Throughout nearly as in melina but narrower and more elongate 

 in form, with stronger and coarser elytral punctures and shorter 

 clypeus, the latter more evenly semi-elliptical, with shallow and 

 less dense rugulose sculpture, the suture evident, feebly sinuate; 

 prothorax about twice as wide as long and differing in being fully 

 as wide as the elytra; hind tarsi longer, the second joint almost half
