370 Mr. F.P. Pascoe on some new Australian Longicornia. 
quam articuli czteri longiore, apice incrassato, basin versus gradatim 
attenuato; articulis tertio quartoque cylindricis, hoc preecedente bre- 
viore; ceeteris lateraliter paulo dilatatis, et quam quartus longioribus. 
Prothorazx elongatus, subcylindricus, capite haud latior. Elytra linearia, 
apice singulorum rotundato. Pedes breves; femora simplicia; tibie 
quam tarsi vix longiores. Pro- et meso-sterna declivia. Abdominis 
segmenta fere eequalia. 
A curious little insect, remarkable for its narrow elongate outline, 
is at present the only exponent of this genus, which differs from 
Isalium in the unusual character of the scape being the longest of the 
antennary joints, and in its very short legs, the tibie being scarcely 
longer than their corresponding tarsi. 
Bebius filiformis. 
B. omnino rufo-testaceus, oculis nigris. 
Hab. South Australia (Mr. Angas). 
Entirely reddish testaceous, with a few delicate greyish hairs, not 
visible, except under a lens; head roughly punctured in front; eyes 
large, black; prothorax with coarse, shallow punctures; scutellum 
narrow, concave, rounded behind; elytra deeply and coarsely punc- 
tured, the punctures crowded and irregular; body beneath reddish 
chestnut, shining; antennze less than half as long as the body. Length 
42 lines. 
AMSIOTYCHE. 
Caput exsertum, pone oculos constrictum, antice subelongatum ; tuberibus 
antenniferis validis, brevibus, approximatis, antice emarginatis, infra 
fronte transversim impressa. Oculi prominuli, reniformes, grosse granu- 
lati. Palpi triangulares, maxillares elongati. Antenne elongatze, 
apicem versus gradatim attenuate, scapo obconico, articulis ceteris 
cylindricis, muticis, quarto quam tertius vel quintus breviore. Protho- 
rax oblongo-ovatus, inermis, disco irregularis. E/ytra prothorace paulo 
latiora, elongata, irregularia, apice singulorum acuto. Pedes elongati; 
femora fusiformia ; tibie et tarsi attenuata; core antic globose, ex- 
sertee. Acetabula antica anguste angulata. Prosternum subelevatum, 
angustum, postice dilatatum. Mesosternum declive. Corpus subde- 
pressum. 
A very distinct genus, referable to the Cerambycine, but distin- 
guished by the cylindrical mutic joints of the antenne combined with 
the almost linear femora. 
Misiotyche favosa. (Pl. XVI. fig. 3.) 
42, fusco-castanea, subnitida; elytris favoso-punctatis, pone medium flavo 
plagiatis. 
Hab. South Australia (AL. Bathurst). 
Dark chestnut-brown, slightly nitid, or having a gloss as if of varnish,
