498 On the Lamellicorn Coleoptera of Larat Island.

Leng. 12°5-15 mm. ; lat. max. 6°5-7-°5 mm. 
In the above diagnosis I have described the male only, 
because, although I have little doubt that I have rightly 
sexbotated the very different forms I regard as the male and 
female, the evidence is not yet conclusive. 
The male i is like C. for besi, Jans., but the sternal process 
is shorter, the sutural angles of the elytra are not sharp, and 
the pale “markings are different. Three male specimens 
found by Mr. Muir are practically identical in their markings, 
which consist of an aril lateral margin to the pro- 
notum, a spot upon the basal lobe, and two minute discoidal 
spots, maa upon the elytra a triangular mark near the middle 
of each, a comma-like spot near ‘the suture behind, a large 
and a small spot between the two last but near the outer 
margin, and an apical lunule. 
The two female specimens are superficially entirely different. 
The pronotum is shining and the pale markings are absent 
from the upper and lower surface alike, except. “that in one 
specimen there are two minute spots upon each elytron. The 
front tibize are short and broad and armed with three blunt 
equidistant teeth, and the hind tarsi are shorter than those 
of the male. 
I believe no well-marked sexual dimorphism has hitherto 
been recorded in the genus Clinterta, and the remarkable 
parallelism between the present case and that of Glycyphana 
disparilis, in which the sexes differ in exactly the same way, 
is very suggestive. It is natural to suppose that some kind 
of local influence is responsible for the occurrence of the same 
phenomenon (not of a usual kind) in two different genera 
inhabiting the same place,
