After careful consideration of the literature and the material of 

 this genus before us, we feel fully justified in placing sumalrana 

 Giglio-Tos in synonymy. A possibility exists that the name should 

 be placed under L. fragilis (Westwood), but due to the inadequacy 

 of the original three-line description of sumatrana, this can be deter- 

 mined definitely only by examination of the type or further knowl- 

 edge gleaned from Sumatran material.

It is clear that the species of the genus are closely related, and 

 particularly albella and fragilis. When compared with fragilis, the 

 present insect is seen to differ in the male sex as follows. Inter- 

 rupted dark line margining pronotum and mesal pair of dots nor- 

 mally very weakly indicated, in discolored specimens sometimes 

 obsolete.^- Tegmina wholly immaculate. Supra-anal plate tri- 

 angular with apex rounded, decidedly shorter than proximal width. 

 Cerci tapering distad to slender apices. 



Unfortunately lack of female material of fragilis prevents com- 

 parison for that sex. Females of albella are readily separable from 

 those of L. lactea (Saussure) by the distinctly narrower marginal 

 field of the tegmina (.8 mm. in width), while those before us are 

 smaller than the female of lactea at hand (length of pronotum 11.4 

 and 12 mm.) with tegmina very weakly milky, except latero-proxi- 

 mad where they are weakly milky, in marginal field where they 

 are translucent, milky and distal portions of marginal fields of 

 tegmina and wings where they are buffy and almost opar^ue.^^

It is extremely probable that Westwood described sexes as indi- 

 cated in the above synonymy. The male was apparently a dis- 

 colored specimen, as the usual striking features of pronotal colora- 

 tion are not mentioned in the description. 



'2 Burmeister's type was in such condition, or this feature was either naturally 

 obsolete or wholly overlooked.
