separated. Posterior coxal cavities completely margined on first visi- 

 ble abdominal sternite. Intercoxal process of abdomen tubular or nar- 

 rowly triangular. Body elongate, cylindrical. 



Genotype. — Apate varia Illiger. (Present designation.) 

 Lesne (1899) erected this genus for 24 species without designating 

 a genotype. The species of this genus are distributed throughout all 

 parts of Africa, southeastern Asia, and the greater part of America, 

 and one species has been described from Europe and another one from 

 Japan. In some species the secondary sexual characters are quite 

 distinct in the two sexes, whereas in other species these characters are 

 not noticeable.

LlCHENOPHANES FASCICULATUS (Fall) 



Bostrichus fasciculatus Fall, 1909, Canad. Ent. 41: 162; Lesne, 1938, in Junk 

 (pub.), Coleopt. Cat., pt. 161, p. 34. 



Since the writer has not examined the type of fasciculatus and the 

 species has been placed in the key solely upon the characters given in 

 the original description, it seems advisable to include the following 

 copy of the original description : 



Bostrichus fasciculatus, n. sp. — Blackish-brown, moderately shining. Head 

 closely punctate, front feebly margined at sides. Prothorax as wide as long, 

 front margin sinuate, with two slender unciform processes ; hind angles promi- 

 nent, dentiform ; entire upper surface strongly though not very densely tubercu- 

 late, and clothed thinly with moderately long, recumbent, subinterlacing yellow- 

 ish-brown hairs, with numerous erect pointed tufts of blackish hairs. Elytra 

 coarsely, deeply, subcribrately punctate, without costae; vestiture similar to
