E/acntis, founded on a species from Borneo to which the appropriate 

 name dclusa was j^ivcn,and referred to the family Melandryidre in eon- 

 sequence of its hcteromerous tarsi. In the Annals and Magazine of 

 Natural History, for 1871, Mr. Pascoe has corrected the error appar- 

 ently at the suggestion of Dr. Leconte. An examination of all the spe- 

 cimens before me shows the tarsi to be heteromerous in both sexes. 



The generic name suggested by Pascoe has priority and must be 

 adopted. 



The following species is new. 



E. longicornis, n. sp. — Dark brownish testaceous, shining, sparsely clothed 

 with greyish hairs. Form moderately elongate, subdepressed parallel. Hend 

 large, densely punctured, darker in color than the rest of the body. Antennse 

 as long as half the body, slender, scarcely clavate, joints gradually broader to 

 tip; third joint very long, as long as the three following together; color yellow- 

 ish. Thorax slightly broader than long, sides parallel in front sinuate near 

 base, hind angles slightly prominent, margin rounded, sub-acute only near the 

 base; surface moderately punctured. Elytra brownish, paler than the thorax 

 ornamented with irregularly placed pale spots; surface punctured rather 

 closely but irregularly. Body beneath piceous shining, sparsely punctulate. 

 Length .12^— .18 J inch; 3—4.5 mm. 



Differs from all our species by the unusually long and very feebly 

 clavate antennae. In the male only do the last three joints exhibit 

 any increase of size over the preceding and then very faintly. The 

 form of body is nearly that of fasciatus and is much less elongate 

 than any of our other species. There is a possibility that this species 

 may be identical with the one for which the n^mQ yuttulatus^liQQ. 

 was suggested. 



Two specimens from near Fort Yuma, California. 



BRADYCINETUS n. g. 

 This name is suggested in place of Amcchanus (preoccupied in the 

 Cerambycidae), Trans. Am. Ent. Soc. 1870, 48. including our species 

 long knowh under the name o^ Athyreus. 



CYCLOCEPHALA, Latr. 

 There is hardly a genus among our Lamellicorn beetles presenting 

 species more closely allied in all their prominent specific charactei'S. 

 The difficulty of naming any of our forms from the descriptions at 

 hand as well as with the various tables presented, has prompted me 

 to seek new, more definite and less comparative characters. I be- 

 lieve all the species in our fauna to be hairy when fresh, consequently 

 this means of grouping them is of no value, while the form of the 

 clypeus although differing among the species, does not present that
