and lialfway between it on the lateral margin, No. 3 ratlier 

 further hcliind 2 than 2 is behind the basal thoraeic, and 

 very ninch nearer the suture, No. 4, small, a little behind 3 

 and in dircet line with the basal thoracic and No. 1, No. 5, 

 towards apex, a little further from the suture than No. 3; 

 an elongate spot on each side of base of pygidium ; on the 

 under side, one on the metathoracic epiraeron, one in the 

 middle of the lateral border of the posterior coxa, and one 

 in the antero-lateral angle of each of the first three ventral 

 segments. Style long, straight, acutely pointed at apex. 



Length 12^ mm., including style ; 8 mm. to tip of elytra. 



A single specimen, Lal)asa, xi. 14 (/?. Veitcli). 



Distinct among all these large, wliite-spotted forms in the 

 lack of scntellar spots on the elytra, in conjunction with 

 the lack of extensive white markings along the base of the 

 thorax. Its nearest ally is probably M. \Q-yuttata, Montr., 

 from New Caledonin, from which it differs in the number 

 and distribution of the spots. It also resembles M. funerea, 

 Pasc., from New Zealand, though in this the white spots 

 are yet fewer. The position of the white spot on the pos- 

 terior eoxaj is unusual, and is similar in M. \Q-guttata ; in 

 most species it is situated in the antero-lateral angle. Of 

 the Australian species M. chrysophora, Lea, is probal)ly its 

 closest ally. 



Mor delta nigroterminata^ sp. n. 



Small, stout, obscurely rufous above, with the head and 

 apex of elytra black, antennse and abdomen paler, rufo- 

 lulvous. Head, except a large space between the eyes, 

 clothed with silvery -grey pubescence; thorax with a 

 narrow line along the anterior margin, a small spot near 

 each anterior angle, and a larger spot on each side of the 

 middle of the base of the same colour ; scutellum strongly 

 transverse but not emarginate at apex, clothed with silvery- 

 grey pubescence; elytra with an elongate oblique spot 

 behind each shoulder, an oval spot just before the middle and 

 not far from the suture, and a squarish spot halfway between 

 this and the apex silvery grey ; the derm beyond this spot 

 is distinctly blacker thau that of the greater part of the 

 elytron. Pygidium acute, almost twice as long as hypo- 

 pygiura. 



Length 4 mm. (style included).
