CERAMBYCID^E 331 



red, opaque; vestiture above very short, sparse and inconspicuous; head 

 finely, closely punctate; antennae (cf ) distinctly longer than the body, 

 the basal joint obconic, the third nearly one-half longer than the fourth, 

 five to ten subequal in length to the third, the eleventh longer than the 

 tenth, with a feebly marked elongate appendage; prothorax apparently 

 a little longer than wide, widest and slightly inflated near basal third, 

 thence strongly narrowed with less arcuate sides to the apex, which is 

 less than three-fifths the maximum width; basal angles much everted, 

 slender and very acute; surface velvety, minutely, sparsely and obscurely 

 punctulate, the median line gradually elevated and prominent from 

 slightly before to well behind the middle; elytra a little wider than the 

 prothorax, three times as long as wide, the sides feebly converging from 

 the base, the apices rectilinearly truncate, with the external angle promi- 

 nent and subspiniform; surface strongly, rather closely punctate, sparsely 

 near the suture basally, the ridge low and feeble, impunctate, the surface 

 linearly subprominent also more externally; sides of the body beneath 

 minutely, densely punctate and silvery-pubescent, more coarsely, very 

 sparsely so and glabrous medially; abdominal segments two to four 

 gradually slightly shorter, the first and fifth longer. Length (cf 1 ) 15-7 

 mm.; width 3.8 mm. Mexico (Guerrero), Baron. [Entomosterna 

 prolixa Bates, Tr. Ent. Soc. Lond., 1892, p. 180]. 



Distinguishable from the next by the feebler sculpture and cos- 

 tulation, larger size and immaculate prothorax; the red color of the 

 prothorax extends entirely across the prosternum before the coxae. 



*Stenobatyle cribrata n. sp. Much smaller, more parallel and shining, 

 subsimilar in coloration and vestiture, except that the red prothorax has 

 a parallel black vitta from near the apex to the black basal margin, and 

 that the red does not extend at all to the under surface; head very small, 

 densely, rugosely sculptured; antennae (cf) but slightly longer than the 

 body, the third joint nearly twice as long as the fourth, five to ten equal 

 but evidently shorter than the third, eleventh but slightly longer than 

 the tenth, not evidently appendiculate; prothorax slightly elongate, not 

 inflated, the sides very feebly converging, evenly and moderately arcuate 

 from base to apex, the latter scarcely three-fifths the maximum width; 

 basal angles but slightly produced obliquely though very acute; surface 

 even, not tumid medially, coarsely, densely punctate, the punctures 

 transversely confluent laterally; scutellum much smaller, less acute; 

 elytra barely at all wider than the prothorax, a little shorter, more de- 

 pressed, more coarsely, very densely punctate throughout, the ridge 

 strongly and sharply elevated, smooth, the surface just exterior to the 

 ridge feebly concave; lateral apical angles obtuse but distinct, not in the 

 least dentiform; under surface and legs nearly similar, except that the 

 dense punctures toward the sides of the body are less fine and the pubes- 

 cence less evident. Length (cf) 10.5 mm.; width 2.4 mm. Mexico 

 (Guerrero), Baron. 



Differs from prolixa as above noted and also in the less pro- 

 duced basal thoracic angles, smaller scutellum, still shorter fourth 

 antennal joint and coarser sculpture of the under surface.
