TANYMECINI. 85 



slightly arcuate, posteriorly sub-parallel, disc moderately convex, densely 

 punctured, sparsely scaly. Scutellum white. Elytra oblong, sides sub- 

 parallel, disc moderately convex, obsoletely striate and with coarse, deep, 

 moderately closely placed punctures, gradually becoming smaller to tip ; 

 surface moderately, densely covered with cinereous scales, irregularly 

 mottled with brown. Body beneath and legs moderately densely scaly. 

 Length .20-. 28 inch ; 5-7 mm. 



The thorax has a median and lateral space partially deprived of scales, 

 giving the surface a vittate appearance. In specimens from the Southern 

 States, the scales become more or less cupreous, and the specimens are 

 usually larger. 



Occurs everywhere east of the Rocky Mountains.

Rostrum as long and nearly as wide as the head, sub-quadrangular, 

 above flat, finely canaliculate, emarginate at tip and with a narrow trian- 

 gular smooth space, deeply triangularly notched at the sides. Scrobes 

 moderately deep, well defined, arcuate, passing downwards at a distance 

 from the eyes. Antennae moderate, scape gradually clavate, attaining 

 nearly the posterior margin of the eye ; funicle 7-jointed, joints 1-2 elon- 

 gate, 3-7 obconical ; club elongate, oval. Eyes large, round, moderately 

 prominent. Thorax sub-globose, truncate at apex and base. Scutellum 

 triangular. Elytra wider at base than the thorax, moderately elongate, 

 parallel, obtusety acuminate posteriorly ; humeri moderately prominent. 

 Metasternum moderately elongate. Intercoxal process broad, oval at tip ; 

 second abdominal segment longer than the two following together, sepa- 

 rated from the first by a moderately arcuate suture. Anterior legs longer, 

 the femora stouter than the others, the tibiae of the same pair denticulate 

 within, and obtusely mucronate. Articular surface of hind tibia3 open, 

 glabrous. Claws free. Body densely scaly. 



H. opalinus, n. sp. 



Form moderately elongate, densely covered with bright-blue scales with 

 greenish and golden reflections, and with short, fine, yellowish setae very 

 sparsely placed. Head and rostrum (and mandibles) densely scaly, 

 sparsely punctured, together as long as the thorax. Thorax sub-globose, 

 truncate at apex and base, slightly broader than long, surface densely 

 scaly, sparsely punctate. Elytra oblong, parallel, base feebly emarginate, 

 surface densely scaly, finely striate, stria} finely and closely punctured, in- 

 tervals flat, and with a single series of setae on each. Body beneath as 

 above ; tibiae rufous, femora darker, anterior femora piceous. Length .32 

 inch ; 8 mm. 



This species is the most brilliant and more decidedly tropical in its 

 appearance of any in the family in our fauna. 



Occurs in Arizona. C. V. Riley.
