GLENEA AFFINIS. 4 
NOTE I. 
DESCRIPTIONS OF NEW SPECIES OF THE LONGICORN 
GENUS GLENEA 
BY 
C. RITSEMA Cz. 
(Plate 1). 
Glenea affinis, n. sp. 5 and Q. 
Belonging to the group of Glenea Delia Thoms., Clytia 
Thoms. and chalybaea Illig. (= picta Weber and Fabr.) 
which group is sufficiently characterized by the obsolete 
shoulders. 
The new species is very closely allied to and strongly 
resembles Glenea Delia Thoms. of which I have three type- 
specimens (from Java) before me, but is at once distin- 
guished by the fulvous posterior tarsi and the similarly 
colored apex of the posterior tibiae, which in Delia are 
blue-black. Moreover in affinis the white stripes are narrower 
and the white spots smaller than in Delia which gives the 
insect a much darker appearance. Finally the sides of the 
thorax in affinis are more parallel in consequence of the 
less divergent basal angles. 
A male (measuring 19,5 mm.) and a female (measuring 
24,5 mm.) from Koetei (Borneo), collected by Carl Bock, 
in the collection of Mr. René Oberthiir. 
I think the four above quoted species may easily be 
identified by the aid of the following key: 
SHOULDERS OBSOLETE. 
Base of each elytron with two white longi- 
tudinal stripes. 
Posterior tarsi blue-black ; white stripes 
broad, the spots large. . . . . Delia Thoms.
