Head nearly horizontal, considerably produced, surpassing the 

 eye by nearly the width of the eye below. Vertex opaque, trans- 

 versely rugose, longitudinally sulcate on the middle line; base ecari- 

 nate; clypeus but moderately prominent, rather strongly arcuated, 

 scarcely distinguished from the front at its base ; cheeks prominently 

 convex; gula horizontal; facial angle less than a right angle. Eyes 

 oblong-ovate, a little oblique, scarcely sinuated before. Antennae 

 inserted close to the eye and much below its middle; much thickened 

 and clothed with short stiff hairs; first joint short, oblong, abruptly 

 narrowed at its base, surpassing the clypeus by a little more than 

 half its length; second joint about as long as the pronotum, distinctly 

 clavate, its apex being thicker than the first joint; third and fourth 

 fusiform, as thick as the apex of the second, the anastomoses very 

 slender. Rostrum slender, attaining the apex of the intermediate 

 coxae. Pronotum transverse, strongly narrowed before, the anterior 

 angles a little prominent, attaining the middle of the hind margin of 

 the eyes; hind margin strongly arcuated, covering the basal lobe of 

 the scutellum; sides carinated and a little sinuated; apex with a 

 broad and prominent collar; surface rather convex and with the pro- 

 pleura strongly deeply punctured. Callosities oval, prominent, 

 distant but connected by a raised smooth area anteriorly. Pro- 

 sternal xyphus distinctly convex with a slenderly carinate margin. 

 Scutellum broader than long, moderately convex, strongly punctured. 

 Elytra moderately convex, strongly punctured; cuneus considerably 

 deflexed; membrane biareolate, surpassing the abdomen by about 

 one-half its length. Second joint of the tarsi much shorter than the 

 first and third. Arolia as in Camptobrochis, short and broad, lying 

 against the base of the long curved claws. Oviduct of the female 

 long ; reaching well toward the base of the venter. 



This genus is closely related to Cimatlan but differs in the thick- 

 ened antennae and the convex xyphus. It bears a strong superficial 

 resemblance to Camptobrochis but may be at once distinguished by 

 the opaque, sulcate vertex and the stout antennae. 



Type of genus, Diplozona collaris n. sp. 



I might add here that for the present I am unable to find any 

 characters by which to distinguish genus Eustictus Reut. from
