Middle and Southern States : two specimens iVum Mis^souri Territory have the 

 fee' entirely rufous, but otherAvise do not differ. One specimen with entirely 

 black thorax was found by me in Georgia; lam strongly inclined to believe 

 that this Irfsl variety is H. oblonga Guerin^ which, however, is said to have the 

 3d joint of the antennae less than half the size of the second. Where both the 

 second and third joints are small, it is diffi( ult to deternjine theii- relaUve pro- 

 portions, and on this account too great reliance should not be placed on the cha- 

 racters given by Guerin in his division of the genus into groups. 



It is certain that this insect must b^ Say's Limp, rvjicollts, as we have no 

 other that will agree with bis description ; from H. collaris and bicolor it differs 

 in having the tborax always slightly dusky in front ; Say's observation that the 

 species has not the power of giving light, added to the fact that the thorax is not 

 produced over the head, point conclusively to the present genus.

Common in the Southern States,.and occasionally found at New York. This 

 species is very distinct from those of the fellowing division, which it resembles 

 in form ; I cannot, therefore, consider it as H. coarctata Gu/trin. The third 

 joint of the antennas is thinner, but not shorter than the second.^ the sides ot the 

 thorax are rounded and very finely margined.

One specimen from Lake Superior and another from IK'ew York. T^ody above 

 luteo-testaceous, tolerably densely clothed with suberect grayish hair. Head 

 nearly black, densely punctular*^ ; antennce black, far.r basal joints testaceous, 

 2d joint equal in length but thicker than the 3d ; together Uhey are a little longer 

 than the 4th. Thorax short, very transverse, very finely punctulale, sides 

 r )unded very finely margined, not concave. Elytra densely, tolerably linely 

 punctulate, without any trace of raised lines. Body beneath blackish, subseri- 

 ceius with brown haar ; feet testaceous. 



On examining a series of specimens, which I considered as belonging to H. 

 variabilis Guer,, I find differences which appear to have been heretofore 

 overlooked, and which seem sufiicient for the definition of several species. As 

 these characters, which are derived from the thorax and from the nature of the 

 pubescence, are not alluded to in previous descriptions,! cannot be certain of the 

 identity of any of our native species with those of Europe. 



G. H. p i c ea, oblonijo-ovalis picea, breviter griseo-pubescens, thorace punc- 

 tulato, lateribus rotundato, subtiliter marginato, leviter concavo, elytris dense 

 punctatis, minime costatis, antennis basi testaceis, articulis 2 et 3 coniunctis 4to 

 louiiioribus, pedibus testaceis femoribus obscuris. Long. -10. 



One spocitrien. Lake Superior. This species is similar to the preceding, but 

 The pubescence is shorter and scarcely erf-ct. The thorax is more densely 

 punctulate, and the sides are reflexed, so as to cause a slight concavity along the 

 margin. The antennae are as in the preceding, but the second joint appears 

 i-omewhat thicker.
