﻿286 LE CONTE— SYNOPSIS OF THE 



f Hoplia monticola Proc. Acad. Nat. Sc. 2. 141. 



Middle and Southern States ; varies much in size and color and also slightly in 

 sculpture, the lines on the elytra being sometimes very faint, and at others quite 

 strong; the flattened thorax with oblique but slightly rounded sides, the silvery 

 scales of the under surface, and the hair-like scales of the elytra readily distinguished 

 it from all others. 



B. Unguis minor" an ticus et medius paulo, vix sesqui brevior. 



8. H. tristis, oblonga, nigra, nitida, undique einereo-pubescens, thorace longius pubescente, latitudine 



paulo breviore, lateribus obliquis rotundatis, pone medium paulo compressis, elytris subcostatis, pygidio 

 et subtus lanceolato-albo-squaniulosa, tibiis anticis subtridentatis, unguibus anterioribus fissis, postico 

 integro. Long. -31.

 One specimen from New York. Differs from all the rest by the total absence of 

 scales on the upper surface. The form is rather more similar to the next than to H. 

 mucorea with which Burmeister compares it. The anterior tibiae have a small tooth 

 above the two large ones. 



9. H. trifasciata, oblonga, fusca, subtus, thorace et pygidio squamis subargenteis dense tecta, capite 



thoraceque pube erecta vestitis, hoc antrorsum angustato latitudine breviore, lateribus subangulatis, elytris 

 castaneis, parce breviter pubescentibus, squamulis pallidis, inaequaliter vestitis, fasciis transversis tribus 

 parum distinctis formantibus, tibiis anticis subtridentatis, unguibus anterioribus fissis, postico integro. 

 Long. -33— -44.

Newfoundland, Lake Superior, New York, Georgia, Illinois. Varies somewhat in 

 characters, the elytra being sometimes almost free from scales, at others almost 

 uniformly clothed with them. Such a specimen would appear to be described by 

 Burmeister, and such a one is now before me ; the upper tooth of the anterior tibiae is 

 almost obliterated in it, and might readily be overlooked, as seems to have been done 

 by Burmeister when he described them as bidentate. I have seen no black specimens 

 like the male described by Say. 



10. H. limbata, longuiscula, atra, subtus et pygidio lsete argenteo-squamosa, supra breviter pubescens? 

 griseo parce squamosa, thorace pilis paucis longioribus intermixtis, latitudine haud breviore, utrinque 

 angustato, lateribus fortius angulatis, late dense albo-squamosis, subargenteis, lineaque postica dorsalialba 

 signato, elytris thorace latioribus, basi, margine externo pone basin, suturaque ad medium et ad apicem 

 dilatata albosquamosis, subargenteis, tibiis anticis bidentatis, unguibus omnibus fissis. Long. -34. 



Two specimens found at Evansville, Indiana. The dilatation of the white suture 

 at the middle forms an oblique fascia reaching two-thirds way to the suture ; the pos- 

 terior dilatation is a spot connected both with the suture and tip. The thorax is 

 hardly narrower at tip than at base. The legs are black, with the thighs sparsely 

 sprinkled with silvery scales.
