PRESERVED IN AMEER, PROM PRUSSIA. 147 



Of this species there is a single male in the Simon Collection of the Berlin Museum. 

 It is very well preserved, as may he seen from the figure, and the texture and 

 puhescence may be easily distinguished. Tlie colour is very dark, only relieved by the 

 smooth transverse bands along the posterior margins of the abdominal segments, which 

 are roach paler. 



The second tarsal segment is but feebly dilated, but possibly the lobe is produced 

 beneath the third sufficiently to warrant its inclusion in the ChelisochhiEe, a position 

 which would be justified by its general appearance, which, like the size and type of 

 forceps, recalls that of Proreus melanocephalus, Dohrn, an Oriental species with which 

 it might well claim relationship. 



It is not possible to be certain as to the existence of the keel of the elytra, but there 

 seems to be one : this feature is rare in the Chelisochinse and does not occur mProrens.

<?■ 



Long, corporis 8-11 mm. 



„ forcipis 3-i „ 



Antennae with 16 segments ; the basal one not very thick ; second minute ; third 

 about as long as the first, cylindrical ; fourth about half as long as third, subclavate, the 

 rest gradually lengthening, all subclavate. 



Head broad, black ; eyes prominent. 



Pronotum transverse, a little broader than the head, all margins straight, and angles 

 rounded ; very dark brown or black, the sides reddish brown. 



Elytra black or deep brown, lighter near the shoulders ; costal keel apparent, posterior 

 margin gently sinuate. 



Wings prominent, smooth, orange-yellow. 



Legs yellowish or blackish ; first tarsal segment slender, as long as second and third 

 united ; second small, dilated ; third short and rather broad. 



Abdomen very dark brown or black, slightly broader about the middle than at the 

 apex. 



Last dorsal segment simple, transverse, posterior margin truncate. 



Pygidium long and rather broad, parallel-sided in basal half, apical half strongly 

 narrowed and acute. 



Porceps remote at base, rather stout, apparently rounded, slightly depressed and 

 dilated along the inner margin in the basal half, elongate, feebly curved and gradually 

 attenuate, with a sharp tooth about the middle directly apically, which terminates the 

 very narrow dilated portion. 



This species is represented by a pair in the Simon Collection (Berlin Museum) and two 

 males in the Klebs Collection (Nos. 2729 and 4181 : the former is the type).
