Male genitalia as described for the genus. 



Material examined: Mindanao, Davao Prov., east slope of Mt. 

 McKinley, 5600 ft., 16.IX.1946 (CNIIM Philippine Zool. Exped. 

 1946-47, H. Hoogstraal), 1 6", holotype, genit. slide 5733. 



A peculiar, unusually colored insect with the facies of a Tortricine. 

 The coloring reminds one of an Articolla species.

Type species: Coenogenes melanancalis Meyrick, 1937 (India). 



The identity of this genus is somewhat dubious. Clarke's illus- 

 trations of the type specimen show that the original description of 

 the neuration is not correct: neither vein 8 in the fore wing nor 

 vein 5 in the hindAving are absent. The densely scaled, unusually 

 looking palpi only remain for the characterization of the genus; 

 and indeed they are very peculiar. There are, however, no males 

 of the type species at hand to support the separation of the genus 

 by peculiarities of the genitalia. The genitalia of the female are 

 not very instructive, being but httle modified. 



The remarkable palpi may be redescribed as follows. Basal 

 segment moderate, elongate and porrect. Median segment strongly 

 dilated anteriorly, triangular, slightly ascending, with rather closely 

 appressed scales along the whole edge, smoothly appressed along 

 the upper edge, upper and lower angles rounded; terminal segment 

 very small, entirely concealed, the whole palpus compressed laterally, 

 but less compressed along its upper edge. Forehead with a dense, 

 thickened, and appressed tuft, projecting in a slender, separate, and 

 darkly colored pencil above middle of face. 



On the strength of the remarkable palpi, I attribute the following 

 species, represented by a single male specimen, to the present genus. 

 I trust that the genital characters of the male of C. melanancalis, 

 still to be discovered, will prove the correctness of this step.
