﻿MELOLONTHLDiE OF THE UNITED STATES. 241 



The inner posterior spur of the same sex is fixed, very small, and sometimes vanishes 

 entirely. The ungues are armed with a short acute tooth just behind the middle. 

 The legs, and especially the tarsi of the male are longer than usual. 



8. L. latifrons, cylindrica, purpureo-nigra, nitida, clypeo rotundato marginato, ad apicem prominulo, 

 capite thoraceque minus dense punctatis, elytris subpruinosis fortius punctatis, obsolete costatis,anten- 

 nis palpisque rufis. Long. -66 — -70. 



New York ; only females seen. Larger than the other species of this group, above 

 and beneath of a shining purplish black ; antennas and palpi pale, tarsi dark rufous. 

 Head flat, not densely punctured ; clypeus longer than usual, more closely punctured 

 than the head, rounded, narrowly margined on the sides, more broadly in front, with 

 the apex prominent in a very slight angle. Eyes small, distant. Thorax one third 

 wider than the head, and punctured like it. Elytra slightly pruinose, strongly 

 punctured, with faint traces of the costas. Breast strongly densely punctured, clothed 

 with sparse short whitish hair. Abdomen sparsely but strongly punctured at the 

 sides and apex ; penultimate segment faintly transversely impressed. Pygidium 

 tolerably densely punctured. Spurs of posterior tibise (female) long and nearly 

 equal. 



9. L. cerasina, cylindrica, purpureo-rufa, parum nitida, capite parcius punctato, clypeo fortius 

 marginato, late subemarginato, thorace elytrisque modice punctatis, his subcostatis. Long. -65. 



One male, Georgia. Similar in form to the preceding, but with the sides of the 

 thorax less rounded ; uniform purplish rufous, not very shining. Head and clypeus 

 sparsely, not strongly punctured, the latter strongly margined, very broadly but 

 faintly emarginate, so as to appear scarcely more than truncate at tip. Thorax 

 moderately punctured. Elytra rather more strongly punctured than the thorax, 

 with faint traces of costae. Propygidium punctured at tip. Pygidium finely punc- 

 tured. Breast densely punctured, clothed with fine short hair. Sides of the abdomen 

 finely and sparsely punctured. 



Male with the club of the antennas much longer than the stem, and the abdomen 

 faintly channeled ; the penultimate segment has a faint posterior excavation at the 

 middle, and two transverse obtuse elevations ; the last segment is deeply foveate and 

 rises at the tip into two slight cusps ; the outer spur of the posterior tibiae is long and 

 slender ; the inner one is completely wanting. 



10. L. e p h i 1 i d a , cylindrica rufo-testacea nitida, capite thoraceque obscurioribus, illo dense fere con- 

 fluenter punctato, clypeo fortius marginato, late emarginato, thorace sat dense, elytris fortius punctatis, 

 obsolete costatis. Long. -70.

 Trichestcs cphilidia Burm. Lamcll. 2, 2d, 359. 



Georgia and New York ; only males observed. Differs from the next by the more 

 densely and finely punctured head, less deeply emarginate clypeus, and by the some- 

 what more robust form.
