1894.] HEMIPTERA-HETEROPTERA OE GRENADA. 211 



member dark piceous, wrinkled and armed with a small process at 

 tip. The anterior femora closely spined beneath, the tibiae with a 

 few remote long teeth ; middle and posterior femora unarmed, 

 having a dark band next the tip, the corresponding tibiae slender 

 and simple. Hemelytra smoke-brown throughout, with the veins 

 darker. Tergum rufous, infuscated on the middle; the venter 

 highly polished, obscure luteous. 



Length to tip of venter 5 mm. ; width of pronotum 1 mm. 



Only a single specimen ( 2 ) was obtained. It was found at 

 Balthazar, at an elevation of 250 feet above the sea, on March 

 18, in second growth, and was beaten from vines. 



Oncerotrachelus, St§I. 



Oncerotrachelus coneormis, sp. nov. 



Fusco-luteous, pubescent. Form narrower than O.acuminatus, Say. 

 Head behind the eyes suborbicular, polished, minutely denticulated 

 beneath ; eyes black, large, round, coarsely granulated, carried a 

 little above the surface of the front ; rostrum reaching to the 

 posterior end of the anterior coxae, bristly rather than denticulated 

 beneath the joints, the basal joint as long as the head ; antennae 

 pale fuscous, set with erect bristly hairs, the basal joint about as 

 long as the head, pronotum, and scutellum united. Pronotum 

 clothed anteriorly with erect hairs, darker on the anterior lobe ; the 

 posterior lobe almost bald above, highly polished, with the latero- 

 posterior margin callous, erect, pale testaceous, and endiDg above 

 in a tooth ; the posterior margin pale, a little sinuated each side 

 and marked with a short suture behind each sinus. Scutellum 

 with a pale, scarcely elevated, spine at the apex. Legs pale f usco- 

 testaceous, distinctly pubescent. Hemelytra a little narrower than 

 the posterior part of the abdomen ; the clavus and costal margin 

 pale yellowish, the rest of the surface dusky. Underside, including 

 the venter, with an uneven stripe each side extending from the 

 propleura to the tip of the venter. 



Length to tip of venter 4 mm. ; width of pronotum scarcely 

 1 mm. 



Three specimens were captured at Balthazar, April 1 and 

 August 6-10, at an elevation of 250 feet above the sea. They 

 came to the light at night. 



This species is very closely related to 0. acuminatus, Say ; it 

 differs, however, in being narrower and smaller, in having erect 

 sharp-pointed humeri, and in the absence of the stouter teeth 

 on the surface of the basal joint of the rostrum.
