LANGURIA. 11 



give a fresh description : — Head and thorax clear red, very finely and closely but obso- 

 letely punctured. The latter is oblong quadrate ; the base rather narrower than the 

 front, truncate, scarcely sinuate, and finely margined ; the basal striolae represented by 

 two triangular foveae. Antennae, legs, pectus, and abdomen black. Elytra black ; the 

 seven striae, and the sutural and submarginal striae also, with distinct, close, but not 

 very deep punctures ; the interstices not quite smooth, the sculpture consisting of very 

 obsolete punctures and irregular elongate impressions. The prosternum is nearly 

 smooth, faintly transversely strigose in the middle, the sides with a few scattered 

 punctures. 



b. Head black. 



3. Languria capitata. 



Nigra ; prothorace subquadrato, postice vix angustato, modice convexo, rufo, margine antico tenuiter nigro, 

 crebre subtiliter punctate) ; elytris punctato-striatis, interstitiia crebre seriatim punctulatis. Long. 8^-10 

 millim. 



Eab. Mexico (coll. Gorham), Presidio (Forrer). 



Head black, sparsely punctured ; piceous or rufous towards the base and beneath. 

 Thorax rather shorter than in L. sanguinicollis ; the sides very little rounded, except 

 at the front, narrowing very slightly to the base, the latter nearly straight ; the basal 

 striolae faintly impressed and short. Elytra as in L. Iceta; appearing at first sight 

 multistriate, owing to the series of interstitial punctures being almost as distinct as the 

 striae. Abdomen nearly smooth, the apical segment punctured and finely alutaceous. 

 Legs black, the front coxae reddish. 



This insect is allied to L. Iceta ; from L. collaris the form of the thorax at once 

 separates it. 



Three specimens, also one in my own collection. 



4. Languria aculeata. (Tab. I. fig. 17.) 



Picea, nitida ; capite nigro ; prothorace rufo ; elytris nigro-cseruleis, obsolete punctato-striatis ; antennarum 

 clava rufo-testacea ; pedibus piceis, basi rufis. Long. 9 millim. 



Hab. Mexico, San Andres Tuxtla (Salle). 



Head black, minutely punctured. Antennae with a narrow, elongate, and laxly 

 articulated club of five joints ; the apical four joints equal in breadth, the seventh joint 

 (the basal one of the club) triangular and narrower ; from the base to the seventh joint 

 they are pitchy, the club itself being clear testaceous-red. Thorax rather longer than 

 wide, the sides rounded, the disc convex, the base margined, the hind angles rectangular ; 

 without striolae. Elytra steel-blue at the base, black towards the apex, distinctly 

 punctate-striate ; with transverse depressions (possibly not normal but present in the 

 three specimens before me), and consequently somewhat uneven ; interstices smooth ; 

 their apices strongly acuminate and polished, and, in one example, divaricate; the
