closer. Scutellum extremelj short aad broad, with a notch 

 in the middle of the apex, so that it seems to consist of two 

 parts. Elijtra parallel-sided, apices strongly roauded indi- 

 vidually, with an elongate sutural gap, the shoulders slightly 

 raised and a little wider than the thorax in line with and 

 including the lateral tubercles ; on each elytron there are 

 three ivory-like streaks — one is close to the suture, none 

 attain the apex, the central one is the shortest ; the punc- 

 tures are reddish, rather fine, regular, and not at all close as 

 far as the middle, behind this they become large but shallow 

 and more distant, and they lose the red colour. 



Antennce pubescent, the hairs neither very long nor coarse; 

 first joint closely punctured, the third joint reaches the base 

 of the thorax, it is slightly longer than the fourth, but shorter 

 than the fifth ; the eighth attains the extremity of the body. 



Underside pallid, the head punctate, transversely grooved 

 behind ; prosternum punctate, with some rug{B across the 

 middle; metasternum with a median groove, it is finely 

 punctured and transversely wrinkled ; terminal segment of 

 abdomen transversely quadrate, truncate behind^ with long 

 pubescence. 



D. cegrota^ Bates, is the only similar form ; in it the thorax 

 is more narrowed anteriorly, the hinder tubercles are placed 

 behind the middle, the insect is darker and more closely and 

 coarsely sculptured, the antennse are thicker, and the head is 

 narrower.

Ligar's Bush, Papakura, One individual only. 



Group Lamiidse. 



Hyholasius optatas^ sp. n. 



Oblong, robust, rufo-piceous ; legs and antennas pale infus- 

 cate red, the two basal joints of the tarsi darker than the 

 others ; rather closely covered with greyish-yellow decumbent 

 hairs, on the elytra they are thinner or absent on some parts 

 so as to cause a spotted appearance. 



Head finely sculptured, slightly impressed near the hind 

 margin of the eyes. Thorax broader than long but not short, 

 with very fine indistinct granular sculpture, which, however, 

 is better defined and closer on the basal depression ; lateral 

 tubercles large but not acute, placed behind the middle ; on 

 the disk before the middle there is a pair of very slight 

 elevations ; there is no frontal constriction, there being only 

 a superficial transverse depression. Scutellum densely pilose.
