HEMIPTERA. 125 



Genus 10. STIBAROPUS, n. g. 



Head very little longer than broad, rounded in front, with the 

 apex very slightly emarginate; the margins closely set with 

 spines, the lateral lobes meeting beyond the central. Eyes of 

 moderate size, globose, prominent. Ocelli very large, distant, 

 placed close to the anterior margin of the thorax. Antennae 

 short, not twice the length of the head, of five joints, gradually 

 increasing in thickness from base to apex ; basal joint short, se- 

 cond very small, third longest, gradually thickened towards the 

 apex, fourth and fifth ovate. Rostrum slender, reaching the 

 posterior coxae, inserted close to the apex of the head ; basal and 

 third joints about equal, second and fourth also about equal, 

 longer than the others, fourth thinnest. Body oblong-ovate. 

 Thorax a little broader than long, almost semicircular in front. 

 Scutellum rather longer than broad, with the apex broad. Mem- 

 brane of the elytra well-developed, passing the apex of the ab- 

 domen, with longitudinal nervures. Anterior tibiae compressed, 

 cheliform, slightly curved, with the basal half of the outer mar- 

 gin set with spines, the inner margin fringed with hairs, espe- 

 cially at the apex; tarsi inserted at about one-third of the length 

 of the tibiae from the apex, very long and slender, three-jointed ; 

 basal joint very long, forming more than half the tarsus, second 

 shortest, third about half as long as the first ; intermediate tibiae 

 somewhat clavate, strongly curved, thickly set with spines on the 

 outside, especially towards the apex ; tarsi inserted at the apex 

 of the tibiae, rather short, three-jointed, apical joint longest, 

 second shortest ; posterior legs very thick, rather short ; thighs 

 very broad, somewhat compressed; tibiae very short, sparingly 

 spinous on the outside, much enlarged and abruptly truncated at 

 the extremity, forming a large oval disc, surrounded by closely 

 set spines ; these spines at the lower part of the inner margin 

 run oif in a single oblique line across the inner surface of the 

 tibia, towards the upper margin, and in the angle formed by this 

 row of spines with the truncated posterior margin, the tarsi are 

 inserted, and lie so concealed by the ring of spines surrounding 

 this margin, as to elude detection except upon a very close exa- 

 mination; the tarsi are short, three-jointed, the apical joint 

 longest, the basal joint very little longer than the second.
