PELARGODERUS SIJTHOFFII, N. SP. 



BT 



C. RITSEMA Cz. 



Agreeing with P. semitigrinus Rits. (Notes Leyd. Mus. 

 Vol. VII, p. 43, pi. 3, fig. 3) but easily recognizable by 

 two very obvious differences. 



In the new species the elytra are very distinctly speckled 

 with white, about as in P. alcanor Newm.; in semitigrmus, 

 however, they are indistinctly speckled with greyish. 



In the new species a narrow dirty white stripe is present 

 along the middle of the apical fourth of each elytron, 

 extending down to the pointed outer angle; in semitigrinus 

 this apical stripe is entirely wanting. 



Two males and one female from Padang Sidempoean 

 (West-Sumatra) belonging to Mr. P. F. Sijthoff's collection. 

 One of these males is now in the collection of Dr. H. J. Veth, 

 the female in that of the Leyden Museum. 



Obs. Pelargoderus nigromaculatus, described by me in 

 December 1897 and published in Notes Leyd. Mus. Vol. XX, 

 p. 34, has been concisely described in the same year by 

 Dr. L. von Heyden under the name of Pelargoderus trigo- 

 nalis in Abh. Senckenb. Ges. Bd. XXIII, p. 573. 



Pelargoderus [Rhamses) vitticollis Thorns. (Ann. Soc. Ent. 

 France, 1878, Bull. p. 18) of Avhich I have examined the 

 type in Mr. R. Oberthiir's collection = Epepeotes plorator 

 Newm. and consequently not from Borneo but from the 

 Philippine islands.
