This insect varies very considerably in size but otherwise 

 very little. It is the most strongly punctured species 

 known to me in this section of the genus. It is easily 

 recognised by the orange-coloured mark shaped like a 

 hammer upon each elytron, 



P. hicolor, Westw., the type of which is in the British 

 Museum, and which Dr. Ohaus has wrongly stated to be 

 identical with F. fcmorata, Burm., is a very distinct species 

 also belonging to this group. It is unfortunate that Dr. 

 Ohaus has called the section to which the latter insect 

 belongs (the gen. Cmlidia of Dejean) " the bicolor group." 

 The original of this sub-genus, from Dejean's collection, 

 will be described later. P. hicolor resembles P. femorata in 

 coloration but is very different in structure and easily 

 distinguished by its much larger size, more rectangular 

 form and naked legs and pygidium. The two sexes are 

 alike. This is one of several cases in this genus of super- 

 ficial resemblance between species not nearly related. 



P. hinotata and P. Horsfiddi are two more insects simul- 

 taneously described by Westwood from the same part of 

 the world (Java) of which the first appear to be all females 

 and the second all males. The type of the former is un- 

 known, and I have only seen two specimens, which are 

 both females, but the type of the latter and a number 

 of other specimens which I have examined are all males. 

 This confirms Dr. Ohaus' suggestion that these are the 

 sexes of one species; and as they are almost alike except 

 that the female is quite black with a round spot on 

 each elytron near the scutellum, and the male uniformly 

 dark brown, and as no other similar form is known 

 from the same island, this is in all probability correct. 

 In this case the name will become P. hinotata, Westw., 

 that form having been first described in Westwood's 

 paper. The insect described by Burmeister from Dupont's 

 collection as P. hinotata, Westw., is entirely different, as 

 shown by his reference to a serial puncturation on the 

 elytra and sinuatcd pale marks. To avoid confusion this 

 species may be re-named P. Duponti. M. Oberthlir possesses 

 an insect from Southern India formerly in Van Lansberge's 

 collection (which included that of Dupont) and labelled by 

 the latter " hinotata, Burm., type." I have seen six 

 specimens of the insect, which is of a deep mahogany 

 colour, and all are males. 



Very near the male form of P. hinotata is the male
