elytrisque costis infuscatis. 

 L. 14 mill. 



Elongate, dull pale brown ; the head, eyes prominent, fore- 

 head and area between the eyes dusky, neck sometimes 

 flavous ; the thorax darkish brown, with a median longitudinal 

 space, which widens out before and behind, pale ; the elytra

fused coloration on a somewhat raised 

 patch in the interstice, behind this patch 

 the inner costa is usually interrupted and 

 bent towards the suture, it reappears over 

 the hind coxte and again before the apex ; 

 outside the long outer costa is a dark line, 

 which towards the apex breaks up into 

 dusky points (but this is a variable cha- 

 racter), the lateral rim of the elytra is also 

 dusky ; the antennge dusky brown, with 

 the two basal joints paler; the legs pale, 

 with the apices of the femora dusky ; male, 

 posterior thighs largely swollen, and the 

 hind tibise much shorter and thicker than those of female. 

 The colour and form of the elytral costge are somewhat 

 variable ; sometimes the costaj join three times, as in fig. 9. 



Hah. Kiga, Hakone, and Miyanoshita. Repeatedly beaten 

 from pear- and cherry-blossoms in May. 



This species differs from all in this series in the enlarged 

 femora of the male being yellow, and in the female the 

 abdominal segments are of the same colour. 



Hah. Nagasaki. In the flowers of Deutzia and Spircea in 

 spring.

(Edemera Imidicollis, Motscli. Bull. Mosc. i. p. 174 (1866). 

 Oncomera vitticollis, id. ibid. 



Motschulsky's descriptive lines seem to refer to one species, 

 but from their peculiar construction appear to have been 

 written at different limes. Oncomera vitticollis is compared 

 to One. jlavipeSy evidently meaning CEdemera flavipes^ Fabr.
