212 DIURUS TARSATUS. 



Hab, Sumatra : Kotta Zuydewiju near Solok (J. H. Scha- 

 gen van Leeuwen). — A single specimen (female). 



The two following species are remarkable by their 9- 

 joiuted antennae, the three apical joints being compact 

 without showing the slightest traces of articulations. 



2. Diurus tarsatus, n. sp. cT ')• 



A very distinct species, not only by the 9-jointed an- 

 tennae, but also by the dilated and densely fringed ante- 

 rior tarsi of which moreover the basal joint is equal in 

 length to, if not longer than the succeeding joints taken 

 together. 



Length (the rostrum and tails included) 46 mm. — Dull 

 black. The head and basal portion of the rostrum are co- 

 vered with large punctures ; on the uppersurface these 

 punctures are provided with thickened dircy white scales , 

 on the sides however with scale-like setae ; the head is more- 

 over provided with a longitudinal scaleless furrow and with 

 a fovea between the eyes. The sides of the head and of 

 the basal portion of the rostrum , which inter alia are con- 

 siderably thicker and moreover shorter than in D. forci- 

 patus Westw., are parallel, the eyes two times their dia- 

 meter from the posterior angles. The antennae are in- 

 serted near the apex of the rostrum , and , although elon- 

 gate , shorter and stouter than in forcipatas ; they are but 

 little longer than the head and rostrum taken together; 

 the first to 8th joints are densely covered with setae which 

 form a sort of fringe on the undersurface and are black 

 on the first to 6th joints (on the three basal joints they 

 are however intermixed with pale colored setae), white on 

 the 7th and 8th joints; the 9th or apical joint is finely 



1) A male specimen of a closely allied species from the Philippine-islands 

 (Manilla) is in the possession of Mr. G. Power; the anterior tarsi are how- 

 ever neither dilated nor fringed.
