 Plesiotyrus ^aMi. nov. 



Head sulxivatc, as liroad hut liardly as lung as the thorax, vertical 

 and not |)roh)nged anteriorly; antcnnal tuheicles narrowly separated, 

 not very prominent. lOyes moderately large, only slightly convex, 

 placed at the middle of i-acli side. Tliora.x oviform, relatively small, 

 rather longer than hroad, without discernible impressions. Klytra not 

 quite as long as broad, widest at the extremity, curvedly narrowed to 

 the same width as the thorax at the base; with tlistinct sutural striae, 

 the dorsal much less definite, botli deepest, but not foveiforni at the base. 

 Hind-body as long as the elytra, .segments 2-.5 detlexed, the basal largest, 

 as Ijroad as the elytia, distinctly margined, obtusely convex V)el)ind, 

 much depressed and thickly i)ul)escent at the base. Legs moderately 

 elongate but thick. 



Antennae of nearly uniform thickness from the basal joint to the 

 penultimate, the terminal largest, as long as Otli and 10th united, 

 obtuse at the a))ex ; 2nd sulwviform, and nearly as hmg as the cylin- 

 drical 1st; joints 6-8 sliglitly smaller and more moniliform than tlie 

 preceding three, none elongate; 0th and 10th transverse and i-ather 

 broader. 



Maxillary palpi short, not loTiger than tlie head; basal joint short 

 antl slender, 2nd longest, its l)asal lialf vrry slender, tlie otlier clavate; 

 3rd subglobular, with a very short, thin basal stalk; 4th oblong-oval, 

 larger tlian .3rd, subtruncate at tlie extremity, with an acicular ap- 

 pendagi' proceeding fi'om a minute fovea underneath, its basal stalk 

 short and slender. 



Prosternum deeply emarginate. Metasternum convex, but flattened 

 behind the middle. Head with an incurved impression before the eyes. 

 Coxae, anterioi- an<l intermediate, rotundate, the foiiiier subcontiguous, 

 the latter moderately separated, their troclianters longer than those of 

 tlie front pair, lather slender near the base, subclavate at the exti-emity ; 

 posterior coxae distant, with tliick trochanteis. Hasal ventral .segment 

 not visible, thickly covered with ])ube.scence, 2nd lather longer than the 

 3rd and 4th ; .')fh large, deejdy sejnicircularly emarginate, its hind 

 portion margined and ritunded ; tlie enclosed 6th is large and sub- 

 rotundate, with a median suture across it. the apical portion no doubt 

 is the supplementary segment of the male. 



In faciea it mo.st nearly resembles Ti/ror/efii.'i, but differs tlieii'from 

 by the abbreviated palpi, with their aciculate terminal appt'ndages. 

 larger eyes, more rol)ust legs, and thicker, diffeiently formed antennae. 

 Tjirngel iix, M. I?affr;iy informs me, is a good genus, allied to Saulcy's 

 Ti/rn/ixix, a Chilian genus. 



The type, 234.5, now Plesintyrim rrnssi/tex, still uni(|ue, is a shining 

 dark-red insect, with scanty yellowish pubescence, dist.uit .and indis- 

 tinct punctation. and ojtarpic legs. Ft measures l^jiiim. hv j] mm.
