1146 COLEOPTEBA 



Antenna rather short, the four or five basal joints yellow, the 

 others darker, the terminal ones being nearly black ; third joint 

 very small and slender ; fourth distinctly longer than the following ; 

 fifth to tenth differing very little from one another. Head broad, 

 distinctly pubescent, but scarcely punctate. Thorax considerably 

 narrower than the elytra, pubescent, and indistinctly sculptured 

 like the head. Elytra with a distinct punctuation, the punctures 

 moderately close, quite distinct and definite at the base, becoming 

 obsolete towards the apex, and with a rather elongate pubescence, 

 of a yellowish colour, marked with a basal transverse black fascia, 

 a common mark on the middle, which extends backwards along the 

 suture, and unites with an oblique apical mark that encloses a pale 

 space on the outside near the apex of each wing-case. Underside 

 and legs yellow. 



The marks on the elytra are often very conspicuous, but some- 

 times are nearly or quite absent, the basal ones disappearing first. 



The species is closely allied in its structure to C. aqualis, Sharp.

2034. M. erratlCUSj n.s. Elongate, subdepressed, subopaque ; 

 clothed with fine hairs and setae corresponding in colour with the 

 parts on which they are placed ; elytra red, the rest of the body, and 

 the limbs, black, tjie head and thorax shining. 



Head elevated in front, behind this raised space flattened or 

 depressed. Antenna half the length of the body, joints 2-10 pro- 

 longed at inner extremity. Thorax one-fourth broader than long, 

 the sides medially narrowed, obliquely widened behind, posterior 

 angles nearly rectangular, in front of the middle the sides are nearly 

 straight ; apex strongly rounded, base deeply bisinuate ; there are 

 seven more or less angulate depressions, occupying the whole sur- 

 face ; four in front, the two inner ones slightly asperate, the basal 

 two largest, the central one extends from the basal margin as far 

 forward as the middle of the frontal ones, and is diamond-shaped. 

 Scutellum black, deeply emarginate behind. Elytra with five costae 

 on each, the external quite lateral and uniting with the raised suture 

 at the apex ; between these costae there are double series of trans- 

 verse punctiform impressions ; they are covered with slender, elon- 

 gate, hair-like, red scales. Legs compressed, tibiae curvate ; fourth 

 joint of the tarsi broad, broadly excavate above, fifth narrow; 

 claws castaneous, angulate at base. The elytra are not closely 

 applied to each other, so that an evident sutural gap exists. 



Length, 5-| ; breadth, 1^ lines. 



Drury, Pokeno, and Clevedon, south of Auckland. The insect 

 may prove to be an importation, but I have not seen any like it 

 from Australia or Tasmania.
