CLITÜMNUS ABLUTUS. 127 



Subfamily C 1 i t u m n i n a e. 



Clitumnus ablutus Brunner. 



Samarang. July, 1909. Two males, two adult males, 

 one immature female. 



This species was described from Ceylon ') but the present 

 material fully agrees with the original description based 

 on the male sex, except for some color features noted 

 below. Superficially that sex bears a considerable resem- 

 blance to Omiicidina nematodes (Haan), a Javanese species, 

 but from the latter ahhitus may be distinguished by the 

 elongate and unarmed head, shorter antennae and the 

 much smaller general size. One of the present males agrees 

 almost exactly with the original measurements of the 

 species, while the other is very slightly larger. 



The general color of the males is hazel brown washed 

 with sea-green on the sides of the meso-and metathorax, 

 while the femora vary from vinaceous-rufous to vinaceous- 

 cinnamon, the tibise very pale oil-greenish, the median and 

 caudal pair obsoletely banded with brownish, the antennae 

 clay-color, darker distad. 



In Brunner's key to the species of Clitumnus the female 

 runs to C. siamensis, which is a species almost twice the 

 size of ablutus. The nearest ally to the present species of 

 which both sexes are known is serndatus Brunner, a Malayan 

 species found in Java and included in the present collec- 

 tion, the male of which is smaller, less slender, with sub- 

 obliterate granules on the pronotum and base of the meso- 

 notum, while the female has the cephalic femora serrulate 

 dorsad and ventrad and the general proportions different. 



The two adult females before us measure as follows: 

 June, 1910. August, 1909. 



Length of body, 66. mm. 66.5 mm. 



Length of mesonotum, 15.7 „ 15.2 „ 



Length of metanotum (with 



median segment), 10.2 „ 10.5 „
