Tanychilus has a well-developed muzzle ; this has none at all : 

 nevertheless, notwithstanding the other characters, there is a con- 

 siderable general resemblance between the two genera. The type is 

 Metistete (jlhhkoJTis (Ta^ii/chilus), Newman (Entom. !Mag. v. p. 489). 

 T. cistelides of the same author may be another species, but it is un- 

 known to me. 



HOMOTRYSIS. 



Characteres ut in Allecula ; sed antenncp. articulo tertio quam primus duplo 

 longiore, quarto fere a^quali, Oculi angustati, transversi. Tarsi validi, 

 antici art. basali obconico, duobus sequentibus baud longioribus, trans- 

 versis. 



As Allecula stands at present it is far from being a homogeneous 

 genus ; but taking A. morio as the type, ffomotrj/sis differs in the 

 form of the eyes, the proportionate length of the joints of the antenna), 

 and the shorter and stouter tarsi, and especially of the shorter basal 

 joints. The type is Homotrysis tristis {Allecula), Germar (Linn. 

 Ent. iii. p. 201). The following species, remarkable for its small 

 prothorax, has, however, more slender tarsi, which so far weakens the 

 force of this character. 



Homotrysis microderes. 



IT. nigra, pilosula ; prothorace parvo, confertim punctato ; elytris fulvo- 

 brunneis, striato-punctatis ; tibiis brunnescentibus. 



Hub. Victoria. 



Slenderer than II. tristis, the elytra being three times the length of 

 their breadth, and the head and prothorax very nuicli narrowt-r, and 

 the latter also shorter : these are similarly pimctured, but less pilose ; 

 scutellum black, triangular j elytra striato-punctate, the interstices also 

 punctured, pale fulvous-brown, except the suture, whi*;li is tinged with 

 black; body beneath, legs, and antennas black and shining; the tibiae, 

 except at the apex, fulvous-brown. Length 6 lines. 



Htbkenia [Cistelidae]. 

 7/omo^n/M affinis ; sed o«/7tmagni, approximati. ProM o/v/.r basi elytrorum 

 arete upplicatus. 



The largo approximate eyes will also distinguish this genus, inter
