fields, collected by C. W. Kichmond; Hondubas: "Honduras or 

 Panama"; Guatemala; Mexico, Cordoba (Knab). (Most of the 

 specimens are from banana trash in shipments of fruit without exact 

 localities.) 



Remarks. — One of the specimens presented to the United States 

 National Museum from the original Biologia material under the name 

 Myochrous tibialis Jacoby bears the same locality label, British Hon- 

 duras, Eiver Sarstoon (Blancaneaux), as is given by Jacoby for the 

 single type specimen of M. femoralis. It is not the same species as the 

 others in the Biologia material of tibialis and appears to fit very vrell 

 Jacoby's description of femoralis. Dr. P. J. Darlington has compared 

 my drawing of this specimen with the type of femoralis in the British 

 Museum and states that the type of fernoralis, like my drawing, is 

 wider than tibialis and has toothed hind femora, and the punctation 

 of the pronotum and elytra also correspond ; also that the pubescence 

 of femoralis does seem grayer and less yellowish than tibialis. He 

 concludes that I am probably right in referring this specimen to 

 femoralis. 



Jacoby himself stated that it differed from tibialis in having sub- 

 dentate posterior femora and being withotit the transverse ridging 

 of the elytra. If my interpretation is correct, this species appears to 

 be abundant throughout Nicaragua, Guatemala, and Honduras. 

 Specimens have been brought in with shipments of bananas from these 

 countries. It is a broadly oblong beetle with a wide prothorax that 

 is densely and deeply but not at all rugosely punctate. 



MYOCHROUS COENUS, new species 

 Plate 3, Figxjee 6 



From 5 to 6 mm. in length, oblong, dark piceous, shining with a 

 bronzy luster from beneath the moderately dense, yellowish and brown- 

 ish scales, the scales not concealing the sculpture beneath ; prothorax 

 wider than long, 3-toothed, densely and coarsely punctate, elytra with- 

 out definite transverse ridgings or callosities. 



Head covered by scales to the antennal sockets, beneath the scales 

 coarsely and rugosely punctate, a faint median line in some specimens, 

 and the usual occipital ridge on each side of head. Antennae reddish 

 brown with deeper colored outer joints, of the usual proportions. 

 Prothorax wider than long with three well-developed teeth and a tooth 

 at apical and basal angles; disk not very convex, rather flat, with a 

 depression along basal margin ; punctation dense, coarse, and deep but 

 not confluent, a slight tendency toward ridging in basal part where 

 the punctures usually become denser. Elytra without distinct callosi- 

 ties or depressions, regularly striate punctate without any transverse 

 ridging ; scales not so dense and closely appressed as to hide the punc- 

 tation. Body beneath shining under the light, fine, white pubescence,
