iS MEMOIRS ON THE COLEOPTERA 



basally but with the punctured series less approximate and the flat 

 dark sutural interval has the minute punctulation stronger and very 

 much closer; under surface and legs nearly similar, the metasternum 

 more sparsely and evenly punctate medially; sternal pubescence 

 similarly rather long and dense, except medially, the hind coxae 

 about as long as the metasternum and more coarsely and sparsely 

 punctate than the latter. Length (9) 13.8 mm.; width 7.7 mm. 



Honduras (San Pedro Sula) *simulans n. sp. 



Form more narrowly oval, less convex, much smaller in size, shining, dark 

 rufous, the sterna slightly, the upper surface except the elytra much, 

 darker, blackish, with greenish-metallic lustre; legs rufous; elytra pale 

 brownish-flavate, the suture and external edge basally pale brown; 

 head closely, rather strongly punctate, more finely and sparsely 

 basally and densely subscabrous at the middle of the front and on 

 the clypeus, which is rather more than twice as wide as long, broadly 

 arcuate at apex, with broadly rounded angles, the sides becoming 

 parallel only at the extreme base; edges rather strongly and rapidly 

 reflexed, the flexure becoming obsolete at the sides only at base; 

 eyes moderate; antennal club (cf ) as long as the stem; prothorax 

 in outline as in the preceding species, widest at base; surface finely 

 but strongly, sparsely punctate, less finely and more closely toward 

 the sides, the sublateral pit strong; basal bead entire and well defined 

 throughout; scutellum finely, sparsely punctate; elytra a fifth longer 

 than wide, feebly inflated about the middle, very obtusely rounded 

 at tip, having regular and feebly impressed J series of rather coarse 

 deep punctures, becoming close-set and subconfused toward the 

 sides, the second interval broad, with strong confused punctures, 

 the narrow third interval feebly convex, more prominent posteriorly, 

 where its bounding series become deeply impressed; minute sparse 

 punctules of the sutural interval not differing from those of the rest 

 of the surface; sterna black, feebly metallic, the middle coxae rather 

 narrowly separated, the tip of the mesosternal surface more pallid 

 and shining but not tumid; metasternum strongly, densely punctate, 

 the hind coxae coarsely and sparsely, the pubescence moderate; 

 hind tibiae moderately thick, surate. Male with the larger claw of 

 the anterior tarsi not very thick, its upper ramus long, thin, aciculate, 

 not extending quite as far as the tip of the lower ramus. Length 

 (o 71 ) 9-5 mm.; width 5.5 mm. Isthmus of Panama (Colon), -Beau-

The difference in stoutness and in the extent of posterior dilata- 

 tion between the males and females of ellipsis is hot observable in 

 binotata, and the former, which has been regarded heretofore as a 

 variety of binotata and mistaken by Horn, and, following him by 

 myself, for luteipennis Lee., is really well defined and not closely 

 related to binotata. The small umbra and servilis are of a different 

 type from ludoviciana and it is singular that timbra, of which a good 

 series, taken at Atlantic City, was included in a collection of
