8 Mr. C. O. Waterhouse's descriptions of 



the 9th to 11th forming a loose club, as long as all the pre- 

 ceding joints taken together. Palpi with the terminal joint 

 securiform. Tarsi not broad, the 3rd joint not bilobed, 

 furnished with a well-developed lamina ; claws with a very 

 small basal tooth. 



This genus appears to me most nearly allied to Eburi- 

 fera, from which it differs in the long club to the antennae, 

 and in not having the 3rd joint of the tarsi (which are 

 much less broad) bilobed. 



Mathesis guttigera, sp. n. 



Elongata, paraUela, violacea, nitida, parce longe pu- 

 bescens; elytris guttis quatuor flavis ornatis; femoribus 

 basi piceo-testaceis. 



Long. 3^ lin. ; lat. 1 lin. 



Of a beautiful shining blue, tinged mth purple on the 

 elytra. Autennfe long, pitchy at the base, the club long 

 and flat; the apical joint elongate-ovate, a little shorter 

 than the preceding joint. Thorax gently convex, scarcely 

 broader than the head, broadest in the middle, almost 

 impunctate. Elytra a little broader than the thorax, 

 parallel, convex, rounded at their apices, with no distinct 

 punctuation: each elytron has a small yellow spot about 

 one-third from the base near the suture, and a second 

 larger spot on the margin, about the middle.

This beautiful little species has much the same form and 

 colouration as Zorion guttigerum among the Ceramhgcidce, 

 and is probably parasitic upon it, as Mr. Wakefield informs 

 me that the two insects are found associated.
