in the form of the costal field. I have s.-i-u Ijiit few of our manv -p>-ci'-- "f 

 tiiis genus, l)iil Mr. I'lil'-r, who has si-i-n onlv tin- figure ot' the pr<--~<-nt *pe- 

 cies, informs me that it shows mO iblance ill markings to ( '. 



Fi.-h. nf Kurope. The thorax is dark ami more ,,r !.->s iimul,-,] \vitli jia! 

 mottling which appear* to have a transverse dispo.Mtion, lnit tin- condition 

 of none of the specimens allows one to say whether it is as n--ularl\ 

 po~ed as on the heinelytra or not. On these the costal field is pallid with a 

 iln-ky vein extending down the middle, and is very broad just bevoiid the 

 ba>e, hein^ in the middh- of the basal half equal to one-third the entire 

 hreadlh of the heinelytra ; beyond it narrows, and opposite the oblique 

 termination of the corinni is lightly marked with the faintly and delicatcd\ 

 undulate nairo\v, dark, bands of the rest of the heinelytra; the>e are .sonn.- 

 what broader than the intervening pallid spaces, and traverse the cnriiini 

 and clavus alike witli more or less but ordinarily not much interruption at 

 the suture -. on the membrane tlie.-e darker hands become shattered as if bv 

 a jar which has almost but not quite destroyed at once their traiibver.M.- and 

 their linear character.

A robust form with more obscure markings than the preceding but 

 very similar in character. The head and thorax are dark and uniform, 

 and the hemelytra may best lie described as dark, traversed more or 



distincth', more distinctly di>tall\- than next tlie l.ase, \\ilh pal.-, tn-nvi' 

 continuous threads, which crOSS coriinn and (da\n> alike but are stopped by 



the coMal fn Id, \\ Inch is slender and iiearl \- eipial thnm-lioiit ; on the nieni- 

 l)raiie the markings are shattered and present precisely ihe appearance they 

 do in('. \amlii/eei; the markin-s bear much resemblance to th>
