OKTHOLANGUEIA. — LANGTJKITES. 27 



2. Ortholanguria extensa. 



Parallela, nigra ; capite prothoraceque fere glabris, hoc sesqui longiore quam latus, subcserulescente, basi in 

 medio depresso et tenuiter marginato ; elytris subseneo-picescentibus, obsolete punctato-striatis, apicibus 

 latrusculis, parum expansis et minute denticulatis ; pedibus nigris ; tarsis tenuibus, longis. Long. 

 11 1 millim. 



Eab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion). 



Differs from O. elongata by the rather more prominent eyes, and the nearly smooth 

 head and thorax, the only punctures on the head being a few on the depression marking 

 the epistoma and a very few minute ones behind the eyes. The thorax is quite free 

 from punctures, but has a transverse basal impression terminated by a punctiform 

 indication of the striola. The elytra are faintly brassy, especially at the shoulders ; the 

 sutural stria is rather well marked ; their apex accords more with the type of the genus 

 than does that of O. elongata. The apex of the ventral segment is broad and emargi- 

 nate, though very indistinctly so. A single specimen. 



LANGUEITES. 



Langurites, Motschulsky, in Schrenck's Reisen und Forsch. Amurl-Lande, ii. p. 243 (1860); Crotch, 

 Cistula Ent. i. p. 392 (1876). 



This is one of the most distinct genera among the " Languriides." The parallel 

 oblong thorax, the prosternal process smooth and almost horizontal, widened behind 

 the coxse and with its apex nearly straight, the elytra cut out obliquely at their 

 apices (recalling Pentelanguria), and the elongate, loosely-articulated club of the 

 antennae, render its recognition easy. Languria ventralis, Chevr., has nothing in 

 common with the type of this genus, but will be found under Dasydactylus. The 

 typical species appears to be found as far south as Venezuela.
