genera and species of Laiir/uriidfe. 315 



rotundato ; prothorace lateribiis feve parallelis pone medium leviter 

 latiori ; elytris apud liumeros prothorace latioribus ad apicem 

 sensim acuminatis, apicibus divaricatis, denticulatis ; pedibus elon- 

 gatis, tarsis longis sat dilatatis, ouycbio longo teretiori; lineae 

 coxales obsoletae. 



Elongate, fusiform ; head rather large ; eyes prominent and finely 

 granulated ; antennae inserted at some little distance in front of 

 eyes, rather long and slender, with the 7th and 8th joints tri- 

 angularly dilated, andjoints 9 — 11 wider, 11th joint rounded, almost 

 as broad as lOtli ; prothorax elongate, with sides almost parallel, 

 slightly broadest behind middle ; elytra at shoulders broader than 

 base of prothorax, gradually narrowed to apex ; apices divaricate 

 and denticulate. 



This genus appears to bear some relation to Gonio- 

 hmgur'ia, but is at once separated by its antennae, which 

 point to a relation with Douhledaya. 



Compsolanguria concinna, n. s. 



Capita prothoraceque rufis, fere Isevibus, elytris cyaneis ad basim 

 late rufis, corpore subtus rufo, apice abdominis cyaneo, autennis 

 fere nigris basi rufis, pedibus rufo-piceis, genibus obscurioribus ; 

 prothorace latitudine evidenter longiori ad basim depresso, basi 

 striola utrinque brevi distincta impressa ; elytris seriebus punctorum 

 apicem versus obsolescentibus evidenter instructis, apicibus divari- 

 catis, denticulatis ; corpore subtus fere laevi. L. 12 mm. 



Head, prothorax, and under side, except apex of abdomen, red ; 

 elytra cyaneous, broadly red towards base ; antennae as above 

 described; last joint of maxillary palpi slightly securiform; pro- 

 thorax plainly longer than broad, narrower than elytra at shoulders ; 

 elytra gradually narrowed from shoulders to apex, with distinct 

 rows of pmictures, becoming obsolete towards apex ; under side 

 almost smooth. 



Amazons ; in the collections of the British Museum 

 and the Leyden Museum. One of the handsomest and 

 most distinct of the Langiiriidce. 



Compsolanguria teres, u. s. 

 Prascedenti affinis sed minor et angustior, elytris totis cyaneis 

 facile distinguendus. L. 10 mm. 



This species appears closely to resemble the preceding, 

 but it is smaller and considerably narrower, and the
