148 AMERICAN COLEOPTERA. 



ing parallel for a short distance at base ; hind angles rectangular, 

 base obliquely sinuate each side, disk rather deeply tri-impressed 

 Elytra nearly six times as long and one-half wider than the prothorax, 

 one-half longer than wide, surface somewhat uneven, a vague sub- 

 lateral sulcus, bounded externally by an obtuse rounded ridge extend- 

 ing from the numerous nearly to apex. Beneath dull, finely sparsely 

 punctate and feebly wrinkled, last ventral with an obscure pale spot 

 occupying a feeble depression on each side. Length, 8 mm. ; width, 

 4| mm. 



Santa Rita Mountains, Arizona. A single specimen sent 

 me by Prof. Snow. 



Near rugosa Jac., but the latter has the prothorax imma- 

 culate and obsoletely depressed at sides and middle, and the 

 fourth antennal joint one-half longer than the third. 



NEOBROTICA Jac. 

 N. pluristicta n. sp. 



Elongate ovate, wider behind, pale yellow, elytra each with two 

 longitudinal series of three rounded small black spots, one subsutural 

 the other lateral, with a smaller spot just outside the posterior sub- 

 sutural one. Antennae in great part and all the tibiae and tarsi black- 

 ish, the front tibiae pale internally. Antennae about half the length of 

 the body, third joint a little longer than the fourth, the base and two 

 or three apical joints paler. Head sparsely punctate. Prothorax trans- 

 versely subquadrate, sides parallel and feebly sinuate in basal half, 

 broadly rounded and convergent in front, the side margin narrowed 

 and deflexed anteriorly, basal margin oblique each side, the hind 

 angles obtuse, surface impunctate and with a transverse bisinuate or 

 biarcuate impression terminating outwardly in a fovea. Elytra twice 

 as wide as the prothorax, widest at apical third, feebly shining, each 

 with about twenty rather strongly and closely punctured striae, the 

 intervals very narrow, the alternate ones a little more prominent except 

 at sides and apex, where the striae show some tendency to become 

 confused ; sutural angle produced. Body beneath sparsely punctured 

 and pubescent, moderately shining. Basal joint of hind tarsus evi- 

 dently but not greatly longer than the next two. Length, 5.3-6.7 

 mm. ; width, 2.6-3.1 mm. 



Baboquivaria Mountains, Southern Arizona (Snow). 



The elytral spots form three transverse series, a subbasal 

 one with the outer spot on the umbone, the next just behind 

 the middle, and the posterior one at the apical two-fifths, the 

 outer spot being farther back than the inner one. 



This is the first true Neobrotica to be recorded from within
