Genera and Species of Coleoptera. 489 
Meristete [ Cistelide ]. 
Caput pone oculos paulo constrictum, antice breve; clypeus transversus. 
Oculi supra subapproximati, infra distantes. Palpi maxillares articulo 
ultimo latissime triangulari. Prothorax subtransversus, convexus, ad 
latera rotundatus et tenuiter marginatus, basi sinuatus. Elytra anguste 
obovata, humeris obsoletis. Czeteris ut in Tanychilo. 
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 gibbicollis (Tanychilus), Newman (Entom. Mag. vy. p. 489). 
T. cistelides of the same author may be another species, but it is un- 
known to me. 
Homorrysts. 
Characteres ut in Allecula ; sed antenne articulo tertio quam primus duplo 
longiore, quarto fere equali. Ocul angustati, transversi. Tars? validi, 
antici art. basali obconico, duobus sequentibus haud longioribus, trans- 
versis. 
As Allecula stands at present it is far from being a homogeneous 
genus; but taking A. morio as the type, Homotrysis differs in the 
form of the eyes, the proportionate length’of the joints of the antenne, 
and the shorter and stouter tarsi, and especially of the shorter basal 
joints. The type is Homotrysis tristis (Allecula), Germar (Linn. 
Ent. i. 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. 
H. nigra, pilosula; prothorace parvo, confertim punctato ; elytris fulvo- 
brunneis, striato-punctatis ; tibiis brunnescentibus. 
Hab. Victoria. 
Slenderer than H, tristes, the elytra being three times the length of 
their breadth, and the head and prothorax very much narrower, and 
the latter also shorter: these are similarly punctured, but less pilose ; 
scutellum black, triangular; elytra striato-punctate, the interstices also 
punctured, pale fulvous-brown, except the suture, which is tinged with 
black; body beneath, legs, and antennze black and shining’; the tibie, 
except at the apex, fulvous-brown. Length 6 lines. 
Hyprenta [ Cistelidee ]. 
Homotrysi affinis ; sed oculi magni, approximati, Prothorax basi elytrorum 
arcte applicatus. 
The large approximate eyes will also distinguish this genus, inter
