A single specimen, kindly given me some time ago by 

 Mr. C. French. Two specimens also in Mr. Lea's collection. 

 Most nearly allied to a rugaticollis, Blkb., but differs from 

 that species in (1) still more opaque upper-surface, (2) shorter 

 and stouter antennas, (3) smaller and more concealed seriate 

 punctures in the well-defined striae, (4) shorter and more oval 

 form. Type in the author's collection. 



Amarygmus tibialis, n. sp. 



Ovate convex; head, pronotum, and under-side nitid- 

 black, antennas and legs piceous-red, tarsi pale-red, elytra 

 dark purple- violet, moderately nitid, the suture black. 



Head and pj'oiiotum closelj'- and finely punctate, eyes dis- 

 tant the length of two basal joints of antennae, antennae short 

 and stout, gradually enlarging to the apex, all joints short 

 and closely fitted, two apical-joints widely oval. FrofJiorax 

 wide and short, base much wider (but not twice as wide) than 

 apex, subtruncate at base and apex, sides widely rounded. 

 Elytra vvdder than prothorax at base, ovate, striate-punctate, 

 punctures in striae rather large and close (distant the diameter 

 of one), intervals feebly convex and apparently impunctate. 

 Metasternum irregularly, coarsely punctate. Abdomen 

 smooth, all tibiae curved. Dimensions — 4'2 x 2'5 mm.

A single specimen (male) in my collection was labelled 

 by me ^4. diaperoides, Blkb., until I was able to compare it 

 with authentic specimens of that species from the Northern 

 Territory of South Australia. The true A. diaperoides, 

 Blkb., is wider, darker in colour, with the striations more 

 deeply marked, the punctures therein smaller and more con- 

 cealed, and its intervals evidently punctate. ^4. tibialis is 

 also near .4. rufescens (above), but the colour differences are 

 very marked, while the latter has much smaller seriate punc- 

 tures and evidently punctate intervals. The curved tibiae 

 alone distinguish tibialis from both allies, though this may 

 be sexual. Type in the author's collection. 



Amarygmus coepulentus, n. sp. 



Widely ovate, very convex; head and pronotum dull- 

 black, elytra dull blue-green, under-side moderately nitid- 

 black, legs and antennae reddish-brown, femora darker, tarsi 

 flavo-setose. 



Head and pronotum microscopically punctate, elypeal 

 suture straight and deep, eyes separated by a distance equal 

 to the length of basal joint of antenna, the latter with joint 

 three half as long again as fourth, fourth to sixth equal, 

 seventh to eleventh successively enlarged and obconic.
