coarsely punctui'ed, each puncture bearing a fine, scale-like hair, flanks densely 

 clothed with larger, yellowish scales. Elytra one-third wider at the base than 

 the prothorax. about as loug as wide, broadly rounded on the sides and not ob- 

 viously narrowed behind, basal margin elevated, deeply striate, striaj nearly as 

 wide as the interspaces, closely and coarsely punctured, interspaces convex, some- 

 what shining, indistinctly mottled with fine white scales, a conspicuous white 

 spot of condensed scales on the third interspaiie a little more than one- fourth from 

 the base, and another near the apex, a less conspicuous spot on the seventh inter- 

 space, about two-fifths from the base; pygidium coarsely punctured, punctures 

 not crowded, underside coarsely punctured, less densely on the abdomen: femora 

 infuscate about the middle, annulate with white scales. Length 2.5-2.75 mm. ; 

 0.10-0.11 inch. 



% . Last ventral segment of male not impressed. 



Hab. — Florida, Georgia. 



Two specimens, Dr. Horn's and Mr. Ulke's coll. The resemblance 

 of this species to Ctelogaster litumtus has been mentioned under that 

 species ; it is much less mottled with pale scales. 



PERENTHIS gen. nov. 



Beak stout, widened towards the apex, scrobes oblique, at a dis- 

 tance from the eyes ; antennae stout, inserted two-fifths from the apex, 

 funicle 6-jointed, first joint stout, rather short, joints 2-3 a little 

 longer than wide, 4-6 transverse, gradually becoming wider and 

 merging into the rather small, elliptoidal clava. Head wide, eyes 

 large, moderately prominent with slightly elevated orbital ridges ; 

 prothorax not much wider than long, without ocular lobes, lateral 

 tubercles very small, almost obsolete, anterior margin straight, with- 

 out cusps; scutel not visible. Elytra rather suddenly wider than 

 the prothorax, oblong, sides subparallel ; jjygidium nearly perpen- 

 dicular ; |)rosternum very short in front of the coxie, very widely 

 emarginate, witliout ante-coxal ridges; mesosternum declivous, meta- 

 sternum longer than the first ventral segment, second ventral seg- 

 ment as long as the two following united, the third segment very 

 little narrowed on the sides ; anterior coxce not very prominent, 

 narrowly sejjarated, middle coxse about three times as widely sepa- 

 rated as the anterior. Legs slender, femora not clavate, mutic, tibiae 

 parallel, not armed at the apex, tarsi long, third joint feebly bilobed, 

 fourth nearly as long as the two preceding joints, claws simple. 



A peculiar insect forms the type of this genus. In form and 

 habitus it rather approaches Phytobms, to whicli it becomes still 

 more closely related by the slender tarsi with the third joint but 

 feebly l)ilolK'd. A single species.
