D1APHOROJIERU.S QUAiiRicOLLis Cliaudoir. 



A specimen which I identify as I), quadricollis Chaud., from the description, 

 iiiis been sent to me by Mr. Lea for examination. 



Dee]) black; prothorax with sides lightly sinuate before base, basal angles 

 square but obtuse at summit, lateral ba-sal impressions imininctate; elytra with 

 puncture of third interstice more distant from apex than usual. Length, 8.5 mm. 



Ilah. — Zeehan (Lea). 



DiAPiioiiOJiKitus viRiDiPEXXiSj sp. nov. 



Oval, convex; head large, eyes prominent, lightly inclosed at base, mentuni 

 toothed; prothorax transverse, wider across base (2 mm.) than apex (1.5 mm.), 

 basal angles obtuse; elytra ovate, convex, strongly and fully striate, second inter- 

 stice with a very short striole at base, third interstice with a puncture about 

 posterior third, humeral angles dentate; undersurface glabrous; abdomen in (? 

 with a well marked, median, basal, shallow impressicm ; point of prosternum 

 sinirsely setulose; tirst joint of hind tarsi long, about as long as two succeeding 

 joints together; 6- — Four anterior tarsi dilatate, joints 1 — i densely clothed with 

 squamae beneath, the squamae arranged in longitudinal rows. Black, nitid; elytra 

 bluish green; femora piceous; tibiae, tarsi, antennae, and palpi ferruginous. 



Head convex, not narrowed behinil eyes (1.5 mm. across eyes); post-ocular 

 part of orbits small, rising obliquely but abruptly from head. Prothorax laevi- 

 gata, convex, broader than long (l.ti x 2.2 mm.), roundly and decidedly narrowed 

 to apex, very lightly and obliquely narrowed to base; apex lightlx' emargiuate, 

 angles obtuse ; base truncate, angles obtuse but marked ; median line obsolescent ; 

 border entire. Elytra shortly truncate-oval (4 X 2.8 mm.), convex, strongly de- 

 clivous to apex; ai^ical curve short, hardly sinuate on each side; interstices sub- 

 convex, narrow and convex at apex; ninth interstice wide and with a double row 

 of punctures towards apex. Lengih, fi.5, breadth. 2.8 mm. 



Hab. — Hobart (Lea). The type specimen belongs to Mr. Lea, and another 

 is in my collection, given to me by Mr. H. J. Carter, who found it at Hobart. 



A small species, not like any other species of the genus Bktphoromerus; in 

 general appearance it resembles a species of Hypharpa.r, but is at once distin- 

 guished from the species of that genus by the form of the posterior tarsi, \ihich 

 have the basal joint much longer — longer than tKe elongate inner apical .spur of 

 the tibiae. 



DiAPHOROMERU.S PERATER, Sp. nOV. 



Oval, cou\ex. form robust; head large; prothorax trans\erse, strongly sinuate 

 on sides posteriorly, basal half closely punctate on each side, basal angles rec- 

 tangular; elytra strongly striate, interstices convex, third inqiunctate. humeral 

 angles marked but not dentate. Black. 



Head large (2.(35 across eyes), convex; front obli(|uely de])ressed to anterior 

 margin; clypeus transversely impressed behind anterior margin between lateral 

 setae; clypeal suture distinct, linear, giving off at each end an oblic|ueIy divergent 

 line extending across frontal depression towards eye; left mandible hooked, pro- 

 jecting beyond labrum. right mandible folded under labrum and left mandible. 

 Prothorax broader than long (2.3 X 3.4 mm.) ; base truncate, wiiler (3 mm.) than 

 apex (2.7 mm.); sides rounded anteriorly, sinuate posteriorly and meeting base
