282 CASEY 



maxillary palpi slender, the last joint slender, fusiform and 

 obtusely pointed; eyes similarly coarsely faceted, divided by the 

 sides of the head; body broadly oblong-oval, feebly sculptured, 

 the epipleuraj very wide ; scutellum wholly invisible ; prothorax 

 as broad as the elytra but attached by a broad exposed peduncle.

22 — Body small, oblong or suboval, the head widest at base, the 

 coarsely faceted eyes divided by the acute sides, the front feebly 

 lobed at each side; mentum moderate, exposing the maxillag, the 

 antenna moderate in length, free, slender, the outer four joints 

 broader; elytra oval, not costate, the scutellum minute, trian- 

 gular ; prothorax attached by a broad peduncle ; legs rather short. 



Batuliini 



It is unusual to find such aberrant characters as the median 

 and terminal processes of the anterior tibiae and the externally 

 grooved mandibles, appearing in almost identically the same 

 form in two such completely dissimilar t3'pes as Cnemodus and 

 ErodiuSy these facts showing that, notwithstanding the wonder- 

 fully varied form of the body and its various parts and organs, 

 all of these genera of the Tentyriinge with large mentum have 

 a very pronounced bond of affinity. The tribes foreign to our 

 fauna, introduced for comparison and indicated by the asterisk, 

 are substantially those already recognized, except perhaps the 

 Capnisini and Platamodini, the genera Capnisa and Plataviodes 

 being erroneously considered members of the tribe Tentyriini by 

 Heyden, Reitter and Weise. The Stenosini are represented in 

 my cabinet by Stenosis, Eutagenia, Dichillus and Oogaster and 

 our ArcBoschiziis cannot be associated with them, disagreeing 

 in many important characters as shown in the table ; it is more 

 closely related to Adelostoma, but differs greatly in the form 

 and extent of the mentum. The Batuliini are placed last in the 

 series as forming a more natural transition to the Asidinae of 

 LeConte and Horn, by way of Aiicpsiiis} 



'There are of course a great many other tribes of the Tentyriinae which can- 

 not be considered at present, such as the Salaxini, having for its type the re- 

 markable South American genus Salax, resembling Opatrtun but related closely 

 to the Trimytini and Epiphysini, related to our Edrotini. The genus Hylithus 

 will apparently constitute a tribe very close to the Trimytini, and Hyperops 

 another but slightly differentiated from the Gnathosiini. In my own opinion 

 the genus Himatisnius should constitute a tribe very near but different from the 

 new world Epitragini, by reason of its different facies and more hexagonal 

 mentum. The male in Himatismus is distinguished from the female by a very
