AMERICAN COMPONENTS OF THE TENTYRIIN.I-: 47 I 



a peculiar South American tj'pe, distinguished from any other 

 by the distinct scutelhim, among other characters.' But little 

 more can be said of these genera at present, as all except one of 

 the types above noted are unrepresented in my cabinet, but they 

 doubtless possess many peculiar structural characters besides 

 those which I have inferred from published drawings and 

 descriptions. 



Phloeodes Lee. 



The mentum in this genus differs greatly from that of N^oso- 

 derma in being emarginate at the middle of the apex ; it is small, 

 leaving the maxillce exposed at the sides but covers most of the 

 ligula and the base of the labial palpi ; its surface is impressed 

 along the middle, more broadl}^ toward base, and is densely 

 punctured and squamose throughout. The surface of the body 

 is ver}^ densely covered throughout with small decumbent stri- 

 gose scales, through which smooth shining tubercles protrude, 

 and the surface of the elytra is very roughly and densely pitted, 

 evenly rounded at apex and without ridges or large tuberosities. 

 Along the median line of each elytron there are three small 

 patches of a deep velvety-black color, which upon closer exam- 

 ination, prove to be composed of very short, extremely dense 

 and more hair-like vestiture standing erect. The sexual char- 

 acters of Phlceodes are very obvious and peculiar but do not 

 appear to have been observed hitherto. The male is character- 



' The type of this remarkable genus, which differs from an v of the North 

 American genera, not only in its well developed scutellum and approximate hind 

 coxae, but in having true eljtral epipleurae, obsolescent posteriorly, may be 

 described as follows : — 



Form rather slender and somewhat convex, piceo-rufous, the upper surface 

 moderately shining, in great part glabrous, except the dense pale scales along 

 the sides of the body, on the elytral crests and tubercles and on the legs, 

 the tibiae being broadly banded at the middle with bl.-ick scales ; head with 

 two short longitudinal furrows ; prothorax transverse, constricted near the 

 base, equally wide at apex and base, the surface subglabrous and but slightly 

 uneven, the lateral edges arcuate, coarsely crenulate and the apex approxi- 

 mately bituberculate ; elytra with distinct series of punctures, wider than the 

 prothorax and between three and four times as long, rather attenuate pos- 

 teriorly, obtusely rounded at tip, with a median crest on each elytron to 

 slightly behind the middle and some subapical tubercles. Length 15.8 mm.; 



width 5.8 mm. Brazil (Blumenau) *annulatipes n. sp. 



This species is evidently related to dormeauum Fairm., from ^linas Geraes.
