32 INSECUTOR INSCITI^ MENSTRUUS 



The male, hitherto undescribed, runs out in Brunner's key to 

 gramilosum but is too small for that species, being more as in 

 guttatnm in this respect but differing from this species in others. 

 The elytra are broader basally than in the female and more 

 acutely pointed apically. The cerci are bifid apically, the upper 

 branch much shorter than the lower one ; subgenital plate nar- 

 rowed apically and with a U-shaped apical notch and a pair of 

 cylindrical slender styles about ten times as long as broad. The 

 breast is piceous, as is also the face. The measurements of the 

 single male represented in this collection are as follows : 

 Length : pronotum, 7.25 mm. ; anterior femora, 7 mm. ; poste- 

 rior femora, IG mm.; tegmina, 2G mm.; anal styles, 2 mm. 

 Width : pronotum, posteriorly, 4.5 mm. ; tegmina, at base, 

 across speculum, 6.5 mm., at middle, 5 mm. ; posterior femora, 

 3.1 mm. 



The tegmina of the female are noticeably marked with 

 darker zigzag markings of variable distinctness, a character 

 scarcely indicated in the male discussed above and at variance 

 with the original diagnosis. It is possible that the above male 

 is wrongly associated with the females but without additional 

 material it is thought best not to characterize it as distinct at 

 this time. 



The wings of this species are very lightly fuliginous in both 

 sexes and in this character stands intermediate between the 

 clear-winged genus Platyphyllum of Serville and the fuligin- 

 ous-winged Leurophylliim of Kirby. This character seems to 

 be about the only one so far given for the separation of these 

 two genera and it appears of little value for the purpose. But 

 a structural character may exist to serve for their separation, 

 though I have insufficient knowledge of the forms to point such 

 out at this time.
