Aepediopsis, u. gen. 



Labrum transverse, corneous, broadly emarginate. Mandibles short, stout, 

 not prominent, the right one with a small tooth before apex, both bordered 

 with a membrane towards the base. Inner lobe of maxilla ciliated for nearly 

 the apical half internally, outer lobe with the apex and apical half of outer 

 margin ciliated. Maxillary palpi 4-jointed, the first joiut short, scarcely longer 

 than broad, the second longer, nearly triangular, about 1^ times longer than 

 broad, the third short, as long as broad, the fourth elongate, fusiform, about as 

 long as the first three together. Mentum hexagonal, divided by a suture into 

 anterior and posterior (pars basilaris) portions, corneous, the suture mem- 

 branous. Labium transverse, narrower than the mentum, the lateral margins 

 and a central raphe corneous, otlierwise membranous. Labial palpi short, 

 3-jointed, distant at their attachment to the labium ; last joint short, conical. 

 Tongue broad, membranous, broadly and obtusely emarginate. Paraglossae 

 diverging, overljdng the tongue and not extending beyond it, strongly ciliate 

 internally. Legs moderate; all the coxae contiguous. Tibiae with a few 

 feeble spines along the external margins. Tarsi short, 4-jointed, first three 

 joints short, subequal, the fourth longer than the first three together ; claws 

 simple. Elytra not soldered. Wings rudimentary. Abdomen bordered, of 

 six visible segments, first ventral segment strongly carinate in the middle line. 



A.rpediopsis falklandicfi, n. sp. 



Rather depressed, castaneous, abdomen black. Head and thorax with 

 greasy lustre, elytra rather shining. Antennae and legs reddish testaceous. 

 Length 4'75 mm. In facies ver}^ similar to Arpedium quadrum Gr. Head as 

 broad as long, quadrilateral, narrowed before the eyes, which are small and not 

 prominent; temples smaller than the eyes, rounded ; vertex with a deep round 

 impression on either side above the eyes and a small median fovea ; front rather 

 broadiy impressed on either side ; puncturation limited to the region of the 

 antennal tuberosities and sparing, ground-sculpture well marked, coriaceous. 

 Antennae moderate, the 1st joint a little thickened, stouter than the following, 

 scarcely as long as the 2nd and 3rd together, 2nd shorter than 1st and 3rd, 

 club-shaped, 3rd club-shaped, 4th and 5th of about equal length, oblong, 

 shorter than 3rd, 6th and 7th obconical, a little longer than broad, 8th, 9th, 

 and 10th about as long as broad, 11th dhort, oval, pointed; the last six joints 

 finely pubescent. Thorax slightly broader than long, broader than the head, 

 widest at the junction of the anterior and middle thirds, narrowest at the base ; 

 posterior angles rounded ; disc with a depression on either side of the middle 

 line, extending from near the anterior margin to, and coalescing with, a median 

 impression before the base, thus forming a long U ; median line shining, finely 

 grooved ; puncturation scanty and large, ground-sculpture as on head. Scutelluni 

 coriaceous. Elytra bordered laterally, at the shoulders wider than the thorax 

 at the base, gradually dilated behind, transverse, postero-external angles rounded, 

 scarcely longer than the thorax, uneven, rather shining, coarsely but sparingly 

 punctured, and without visible ground-sculpture.* Abdomen as broad as the 

 elytra, sides almost parallel to apex, bordered, puncturation finer and closer 



* Excepting a few short rays from the punctures, which, however, do not meet one another.
