DIURUS FURCILLATUS. 215 



ded by Lacordaire (Genera des Coléoptères. Tom. VII, p. 

 472 , uote 2) as the male sex of D. furcillatus Gylh. ; it 

 is a distinct species. 



Diurus dispar Pascoe (Journal of Entomology. Vol. I, 

 p. 393) is, 1 have but little doubt, based upon a ma^e (not 

 female) specimen of D. furcillatus Gylh., whereas the fe- 

 male with which it is compared did not belong to furcil- 

 latus Gylh. but to forcipatus Westw. 



The male sex of D. furcillatus Gylh. and the female sex 

 of D. forcipatus Westw. being not yet described as such , 

 I wish to give short descriptions of them : 



Diurus furcillatus Gylh. cT (most probably = dispar 

 Q Pasc). 



Agrees with the female in all respects (even in the short- 

 ness of the tails) besides in the following: The basal por-, 

 tion of the rostrum is somewhat more elongate and more 

 slender , the narrowed apical portion on the contrary about 

 one third shorter and a little thicker ; moreover this portion 

 is opaque. The antennae are a little more slender , and 

 the club decidedly longer. The two basal segments of the 

 abdomen are impressed along the middle , the 4th segment 

 is very short and strongly contracted , the apical one de- 

 cidedly longer than in the female. 



Of this species the collections of the Leyden Museum 

 contain a male and a female ; the former is about equal 

 in size to the type specimen, the latter considerably smal- 

 ler. Both are from Java and were sent over by Macklot. 



Diurus forcipatus Westw. Q (most probably =: furcilla- 

 tus 9 Pasc). 



Agrees with the male in all respects besides in the fol- 

 lowing : The head and the basal portion of the rostrum are 

 somewhat broader , the former moreover a little shorter , 

 the latter considerably shorter being not quite twice as long 

 as the head ; the narrowed apical portion of the rostrum 

 on the contrary is much more elongate (as long as if not 

 longer than the head and the basal portion taken toge- 

 ther), filiform and glossy. The antennae are inserted be-
