248 KHTHYURUS HAQENI. 



NOTE XXV. 



ON A NEW SPECIES OF THE COLEOPTEROUS 

 GENUS ICHTIIYURUS, WESTW. 



BY 



C. RITSEMA Cz. 



Ichthyurus Hageni, d. sp. 



5 9 (which wholly agree with one another) and 1 cf" 

 (which differs from the females by its more coarsely fa- 

 ceted eyes which are moreover more prominent and more 

 approximate on the middle of the face, and by the nar- 

 rower and more elongate apical segment of the abdomen ')) 

 were sent over from Serdang (East Sumatra) by Dr. B. Hagen 

 to whom I dedicate the species. 



Very close to I. forjiculoides Fairm. of Borneo, and , judging 

 from the description (Stett. Ent. Zeit, 1867. p. 114), agree- 

 ing with it in every respect besides in the following : the 

 head is black with the face and a small spot beyond the 

 base of the eyes yellow ; the black lateral band of the 

 elytra suddenly narrows on the apical third (except in the 

 male specimen); the three basal segments of the abdomen 

 above with two lateral , the fourth and fifth with a large 

 median black spot; the sixth and seventli or apical seg- 

 ment immaculate above , the spines of the latter black ; the 

 apical lialf of the fore- and middle femora with a fuscous 

 stripe above, the extreme apex of the hind femora more 

 or less fuscous above.
