DESCRIPTION OF A NEW SPECIES 



OF THE LUCANOID GENUS CYCLOMMATUS, AND 



LIST OF THE DESCRIBED SPECIES 



C. RITSEMA Cz. 



Cy clommatus Frey - Gessneri, n. sp. (ƒ ^). 



This species is allied to Cy clommatus canaliculatus Rits. 

 from Nias (Notes Leyd. Mus. XIII, p. 235) on account of 

 the presence of the notch on the outer upper margin of 

 the mandibles at some distance from the tip. It differs from 

 canaliculatus by the want of the distinct groove along the 

 middle of the pronotum. 



Length of the forma major 40 mm., breadth at the 

 shoulders 8^/4 mm. — Rather pale castaneous, head and 

 thorax slightly darker than the elytra, with aeneous tints; 

 the margins of the mandibles, of the thorax and of the 

 elytra (the basal margin excepted) bronze black; the tarsi, 

 the apical teeth of the mandibles and the scape of the 

 antennae glossy black, the flagellum (with the exception 

 of the three apical joints of the club) glossy brownish red ; 

 the upper side of the femora pale yellowish brown. 



The insect is rather densely covered with whitish scales ; 



1) This species will perhaps prove to be the Cyclommatus Dehaani of Bur- 

 meister which is perfectly distinct from Westwood's Dehaani of which I have 

 examined the type-specimen preserved in the late Melly's collection in the 

 Natural History Museum at Geneva. The latter species is not notched on the 

 outer upper margin of the mandibles at some distance from the tip.
