to near clypeus, this conspicuously notched. Antennae rather 

 long and thin, third and fourth joints subequal. Prothorax 

 with narrowly reflexed sides, angles very feebly armed ; with 

 small and rather sparse punctures, and with much smaller 

 (scarcely visible) ones. Elytra shagreened, with semi-double 

 rows of small punctures, becoming single posteriorly and 

 irregular towards sides; margins very narrow. Fifth segment 

 of ahdomen with a circular median fovea. Length, 6-7 mm. 



9 . Differs in having clypeus less deeply notched, 

 antennae somewhat thinner, and in the abdomen and tarsi. 



Hah.— ^oriolk Island (J. C. Wiburd). Type, I. 3505. 



Fairly close to the preceding species and with somewhat 

 similarly grooved although thinner tibiae, but smaller, 

 differently coloured, with different punctures, and lateral 

 gutter of each elytron much narrower; the parts of the pro- 

 sternum are of much the same shapes, but the sides close to 

 the coxae are scarcely visibly striated, and the flanks are 

 entirely without punctures. On the prothorax there is a 

 large blackish blotch towards each side ; on one specimen 

 each blotch is sharply defined, but on three others its limits 

 are much less conspicuous ; the dark parts sometimes have 

 a vague greenish lustre. Some specimens have the elytra 

 almost of a blood-red. 



COLASPOIDES FRENCHI, n. Sp. 



(3 . Reddish-testaceous ; all margins of prothorax, base, 

 suture, and sides of elytra metallic-green, or blue, or purple. 



Head with rather dense punctures of moderate size ; with 

 a lightly-impressed impunctate median line. Antennae ex- 

 tending to hind coxae, third and fourth joints subequal. 

 Frothnrax with fairly dense punctures of moderate size but 

 rather deep, and denser towards sides than on disc, inter- 

 spersed with much smaller ones. Elytra with rather large 

 punctures with a somewhat lineate arrangement, on apical 

 slope in regular deep striae towards suture, and feebly trans- 

 versely confluent towards sides, larger behind shoulders than 

 elsewhere. Prosternum with front margin of each episternum 

 distinctly elevated in middle ; flanks with small punctures 

 and with a few larger ones scattered about. Fifth segment 

 of ahdomen with a wide median fovea. Basal joint of each 

 tarsus somewhat inflated. Length, 6|-8 mm. 



9 . Differs in being larger (9 mm.), abdomen more 

 strongly convex and non-foveate, and in the tarsi. 



Hah. — North-western Australia: Roebuck Bay (C. 

 French) ; Western Australia (British Museum, from Baly's 

 collection). Type, I. 3287.
