Tliis spe<'ieH is roe.oj;ni/al)le without nuu;h troubles by the very dark 

 motth'd priinaiies, and by the, e(|ually daik, smoky so<',ondarics. The 

 ]M'imari(^H are nuire than usually paraUei, aixl rather narrow. ^IMioso 

 j)oints, to^^ctlier witli the eh'valod vostituro on the ])rima.rioH, will make 

 tlu^ spe<',ios r<M'ot^iii/abl<'.. 'I'horo is little variation; Honu', specimens 

 art^ daikor than others, in Hon\(( tlu^ lines are black rather than brown, 

 and in some th(i Hinoky sunusiou is more distin<*t than in othort*. The 

 Hp<^ci«'S here i«lent.ili<'d as hriiiiiosd is wliat was described by Mr. (Iroto 

 as siihoclirrd. The original descj'iption will lit- either one of t-wo or 

 thre«' sp<'cies, an<l this rel'erence, wliie.h is so dit1er«'nt trom any tluit 

 lias been horet.olbre made, is Iarj;'ely due to the. suf;<;(>slioii made by 

 Dr. Dyar from the larval characters j;iv(Mi. Mr. Uiitler thoiijiht the 

 8i)ceies to ln^ pcrHuasa; but the description will not allow this refer- 

 en<!0. It is possible to mistake suhochrco for a rubbed prrsiiasa, and I 

 believe Mr. Jiiiller's li'ferenco to bo based upon an erroiKMuis dotermi- 

 uation or a bad specimen. The lusid is of very };ood si/o, thoujjfh not 

 ])romin(^nt, the front biil^^ing, the ])a.lpi reac>hin^ to the middle and dis- 

 tinct. The ^(Miitalia. of the male are uni<|uo; the liari)es are rather 

 nai'iow, lon^, a little dilated Just Ix^foro the tip; the clasper is broad, 

 lookinj; somewhat like a mitten with an unusually loiij;- thumb project- 

 iiiif fiom the upper side; I'roin the upper mar;;in there is also a very 

 lonj;, slender, siraiji'ht. process. We ha.ve Ikmc. an almost perfect inter- 

 nuMliate iy\ns betw<M'ii what, may be considered tiie typical lohclitir lorm 

 on IheoiM' hand and the form iisnal in liie itcrsimsd •;roiipoii tli<M>ther. 

 'Vhi'i ant<'rior le;;' of tlu"! male is well develope<l, althouj;li not unusnally 

 lon^'. The feiniir is a little dilated toward balS(^; the tibia is stout, with 

 the epi])liysis inserl.i'd a.bov<^ the muldle.
