albo-plagiatis, apicibus rotundatis ; antennis f uscis, tenuiter griseo- 

 pubescentibus. 

 Long. 21 mm., lat, 7 mm. 



Hob. Borneo. 



Head with an ocliraceous-grey pubescence and with a faint 

 longitudinal raised line on the front. Prothorax with a short 

 transverse depression on the middle of the disk. Elytra 

 without basal crests, roughly punctured at the base, the punc- 

 tures becoming smaller as they pass backwards ; the basal 

 part, especially around the scutellum, and the scutellum itself 

 with an ochreous pubescence ; a large white, somewhat broken 

 patch on each side in front of the middle ; towards the apex 

 the pubescence is again ochreous. The whole of the under- 

 side of the body, except along the middle of the abdomen, 

 ochraceous. The legs entirely ochraceous grey. 



Excepting viciiia, Pasc, this is the only described species 

 of the genus in which the elytra are without basal crests. 



Pharsalia pulchraj n. sp. 



P. mo7'tdli affinis ; protborace supra flavo-variegato, scutello flaves- 



cente ; elytris rdgro-velutiuis, flavo maculatis et fasciatis. 

 Long. 23| mm., lat. 9 mm. 



Hah. Siam. 



Closely allied to Pharsalia [Zygocera) mortalis^ Thorns., 

 with which it agrees very well in its structural details. It 

 is, however, distinct enough by the colour and pattern of its 

 markings. At the base of the elytra is a flavous band well 

 intermingled with black ; just in front of the middle is a 

 tolerably broad transverse flavous band, which is interrupted 

 and mingled with black near the suture. Towards the apex 

 there are three or four irregular flavous spots on each elytron, 

 and some smaller spots in front of them near the suture. 

 The markings on the head are similar to those of moHalis. 



Pharsalia [Zygocera) mortalis^ Thoms. 



This species occurs twice in the Munich Catalogue, once 

 under the genus Galli'pyrga and again as Cereopsius saga 

 (Dejean's Cat.). Recently (Notes Leyd. Mus. vol. ix. 1887) 

 it has been fully described and referred to its true genus by 

 Van de Poll under the name albomaculata.
