channels are represented by costae, so that each elytron has 

 ei^ht or nine dorsal cost;e (the tirst abbreviated), separated 

 by lines of transverse punctures, the costfc thruiselves finely 

 punctured. The thorax has a slight indication of a dorsal 

 channel in front and at the base. The punctuation on the 

 disk is not very strong and the punctures arc slightly sepa- 

 rated, but towards the sides they are stronger and close 

 together. 



A species of the Ileteroraerous genus Praoyena received 

 with this species has similar coloration. 



Paracastalia variegata, sp. n. 



Elongate, blackish feneous ; the elytra with a number of 

 small, irregular, reddish-yellow spots. 



Long. 10 mm. 



Hab. Port Natal. 



Thorax very slightly broader than the elvtra, somewhat 

 narrowed in front, areuately rounded at the sides, strongly 

 and very densely punctured, somewhat rugose. The disk 

 lightly im])ressed, with a slight median impressed line at the 

 base. Slightly pubescent, with obscure yellow spots ; a 

 double spot on the disk, with a minute one in front , a very 

 small one between the central one and the side, and two 

 rather larger ones on the side, one near the front angle, the 

 other at the middle. The elytra are very long. The first 

 costa (after the suture) is short, stopping considerably before 

 the middle ; the second is scarcely convex, except posteriorly; 

 the third is cariniform ; the fourth scarcely convex ; the 

 fifth and seventh convex and distinct; the sixth only slightly 

 convex. Each elytron has a large number of yellow spots, 

 five of which form a small hand at a short distance from the 

 apex. The apex arcuate, with numerous acute equal teeth. 

 The underside of the insect is clothed witli s«hort greyish 

 pubescence. The sternal process is more acute than in 

 allied species. The lateral ridge of the thorax is only repre- 

 sented by a slight sinus at the base. 



The costation of the elytra in this species is intermediate 

 between Durivieri &c. and Bettoni, but the lateral expansion 

 of the elytra is rather less strong. It differs from all ihe 

 other si)ccics in being pubescent below. 



Castalia. 



There has been much confusion in this genus owing to the 



differences in the sexes; and it is regrettable, after these 



difiVrenccs had been pointed out by Dr. Heller (Ucutsch. 



cut. Zeit. 18'J1, p. 135) to be sexual, that Capt. Kerremans
