130 ICHTHYUKUS ZEHNTNERI. 



the first joint small, the three following broader with the 

 external margin strongly ciliate, the following joints elon- 

 gate , narrow , flattened , the penultimate one dilated at 

 the end , the last smaller , subovate , narrow at the base. 



The prothorax convex, 

 3^T~\^^Z3n depressed along the 

 base, shining, almost 

 ***^ smooth on the disc, 



finely and scarcely 

 punctured along the 

 sides. The elytra nar- 

 rowed beyond the middle , minutely and irregularly punc- 

 tured, the tip rounded and deeply excavated above. The 

 abdomen narrowed towards the apex, the apical segment 

 broadly emarginated. The legs slender, the intermediate 

 femora slightly dilated , the intermediate tibiae incurved. 



A single male specimen of this very interesting insect 

 is before me but in such a position as not to allow a 

 more detailed description '). 



I think it best for the present, until the other sex will 

 be known , to refer this species to the genus Ichthyurus , 

 although it is probable that a new genus will have to be 

 established on account of the nine-jointed and strangely 

 shaped antennae. 



Hab. Poespo , on the northern slope of Mount Tengger, 

 in the Pasoeroean Residency , East-Java. The described 

 specimen has been captured by Dr. L. Zehntner, to whom 

 the species is dedicated, on December 27th of last year 

 on the uudersurface of the leaves of a young fig-tree of 

 the genus Urostigma. 



Genoa Civic Museum, May 1897. 



1) Owing to the delicate conditions of the specimen, the drawing of the 

 antenna is exact as far as the basal joints only.
