Melohntha miicorea Germ. Ins. Nov. 129. 



Southern States. Readily known by the more elongate and parallel form. The 

 posterior tarsi are broken, so that I do not know whether the claw is simple or bifid. 

 I have excluded H. h el vo 1 a, as a synonym, since the description mentions linear 

 scales on the elytra ; it seems to me rather to be the variety ofH. trifasciata with 

 almost uniformly colored elytra, and this view accords with the measurements given. 



H. monticola, Mels. Proc. Acad. Nat. Sc. Phila. 2, 141, I have failed to identify. The dimen- 

 sions given are 3| lines by l£, which are the proportions of H. mucorea. From notes sent me by Dr. 

 Melsheimer, it would seem to differ from both that species and H. modesta. The color is brownish testa- 

 ceous, the head and thorax are darker, the latter clothed with short rufous hairs and sprinkled towards the 

 sides with whitish scales, ' the sides are somewhat dilated beyond the middle, slightly incurved posteriorly, sub- 

 rectilinear from its widest portion to the tip; elytra hardly wider at the base than the base of thorax', more 

 than twice as long as the thorax, clothed with short rufous hairs, two obsolete longitudinal raised lines near 

 the middle, pygidium clothed like the elytra, venter covered with small whitish scaly hairs. ' Anterior 

 tibiae bidentate ; inner middle claw less than one half the size of the outer one : posterior claw entire.' 

 Pennsylvania, in Adams County. 



Should the last character be erroneous, it might be referred to the light colored 

 specimens mentioned under H. modesta. 



10. GLAPHYRI. 



A group placed by Erichson among the laparostict Scarabaeidse, but in which, as 

 Burmeister has shewn, the position of the abdominal stigmata ceases to be of value 

 as a primary character. As a group of Melolonthidse, this maybe readily recognized 

 by the labrnm being at the end of the clypeus, and in the same plane ; by the projecting 

 mandibles, the wide parapleurge, and the not connate six-jointed abdomen. The 

 ungues are slender, equal and diverging. The only genus found in the United States 

 is Lichnanthe, which differs from Amphicoma chiefly by the deeply emarginate 

 labrum. 



Lichnanthe Burm. 



1. L. vulpina, nigra, thorace, scutello, pygidio pectoreque fulvo longissime pilosis, elytris seneo-testaceis 

 punctatis, breviter nigro-pubescentibus, postice valde dehiscentibus. Long. -52 — -67.

 Amphicoma vulpina Hentz, Journ. Acad. Nat. Sc. Phila. 5, tab. 13, fig. 3. 



Massachusetts and New Hampshire ; Dr. T. W. Harris. The female is much less 

 hairy, and has the club of the antennas shorter and obtuse. The elytra diverge very 

 strongly along the suture, and are obtusely rounded at tip.
