Head much narrower than thorax, with prominent eyes ; it is moderately 

 coarsely punctured, more finely and closely on the forehead. Thorax of 

 equal length and breadth, widest near the front, very gradually narrowed 

 backwards, posterior angles acutely rectangular, the anterior rather obtusely 

 prominent ; disc nearly plane, sparingly and irregularly punctate, so as to 

 appear almost smooth on some parts, without any well-marked fovea, its 

 sides more closely but not as coarsely punctured. Scutellum triangular, 

 subdepressed. Elytra with obtusely prominent shoulders, broader than the 

 thorax, quite twice its length, widest just before the middle ; on each 

 elytron there are 2 slender minutely punctate striae near the suture, the 

 inner is curved outwards and bordered inwardly by a carina at the base, 

 the broad interstice between these is nearly smooth but has a short basal 

 stria ; including the suture, there are 4 costae behind, the outer pair are 

 very slender and are prolonged to the base, the inner of these is indistinctly 

 duplicated ; between each pair of these carinae there are 2 series of fine 

 pimctures, the 3rd interstice is finely and irregularly punctured throughout. 



Underside subopaque ; prosternum without any tubercle, moderately 

 coarsely and closely punctured, its flanks with a few fine punctures only ; 

 metasternum with a median groove behind, its punctation similar to that of 

 the prosternum ; basal ventral segment nearly as long as the following 

 three combined, not closely punctured. 



Antennae finety pubescent ; 2nd joint bent and inserted in the notch at 

 the hind part of the subglobular 1st ; joints 3-8 quite as long as broad ; 

 9th rather broader and obconical ; 10th double the breadth of the 9th, 

 rounded towards its base ; 11th rather smaller. 



Larger than its New Zealand allies, and readily distinguishable there- 

 from by the different sculpture and more triangular scutellum. 



Length, 6-6;|- mm. ; breadth, quite 2 mm.

Mr. Hall's coadjutor in forming this collection was Mr. R. E. Paynter, 

 whose name therefore has been attached to this species.

 66. Trogoderma pictulum sp. uov. 



Nitid, elongate-oblong, slightly convex ; unevenly clothed with distinct 

 decumbent yellowish pubescence above, but along the sides the hairs are 

 more infuscate and erect ; derm variegate, for the most part rufo-castaneous, 

 the middle of the base and sides of thorax of a brighter red, as are also the 

 base, the shoulders, and other large but not sharply limited spots on the 

 elytra. 



Head dull, small, rather coarsely and closely punctured. Eyes pro- 

 minent. Antennae short; 1st joint thick, reddish; joints 2-4 testaceous, 

 2nd stout, 3rd slender and elongate, 4th subtriangular, as long as its pre- 

 decessor but broader ; joints 5-11 fuscous, each in succession more prolonged 

 inwardly, the 10th quite as long inwardly as the much thicker terminal 

 joint. Thorax at the base twice as broad as it is long, curvedly narrowed 

 anteriorly, the base oblique towards the sides, and at the middle somewhat 

 prominent, so as to partly overlap the scutellum ; it is not definitely granu- 

 late, but the distinct though rather fine punctures are more or less encircled 

 with slightly raised margins. Elytra of about the same width as the thorax, 

 thrice its length, each with a shallow oblique or curvate impression extending
