950 COLEOPTERA 



Epistraims (P. 202). 



1712. E. Jparyus, n.s. Convex, sub-oblong, broad, medially 

 contracted, rufo-piceous ; legs and antennae red ; tarsi fulvous, bear- 

 ing short, erect, pallid hairs. 



Head granulated; eyes minute. Antenna normal. Prothorax 

 nearly as long as broad, considerably narrowed behind, tuberculate. 

 Elytra not twice the length of thorax, humeral angles rounded, bear- 

 ing regular rows of tubercles, those nearest the middle having, 

 seemingly, a puncture at the base of each. Tibiae arcuated exter- 

 nally, and finely ciliated. 



Smaller than E. humeralis and E. valens ; most nearly resembling 

 the latter in sculpture. 



OBS. All the members of this genus are very rare ; they exist 

 amongst decaying vegetable matter, and, when found, their true 

 sculpture is concealed by a thick coating of greyish sappy matter. 



Length, f line ; breadth, nearly \. 



Taken near Ho wick. 



Lithostygnus. 



Nov. gen. 



Body elongate, transversely convex. Head porrected, oblong, its 

 sides deeply excavated for the reception of the antennae ; eyes small 

 but distinct ; labrum prominent ; mentum truncate. Antenna in- 

 serted near the front angles of the epistome ; short, n -jointed, the 

 two basal joints stout, 3-9 sub-equal, club bi-articulate. Thorax 

 cordate. Coxae moderately prominent and distant. Meso- and meta- 

 sterna nearly equal, not abbreviated, impressed. Abdomen with five 

 sub-equal segments, their suture deep and broad. Epipleurce broad, 

 horizontal, narrowed apically. Legs moderate, tibiae grooved near 

 the extremity ; tarsi 3-jointed, pubescent below, their two basal 

 joints equal, and, conjointly, shorter than the third ; claws small. 



An interesting little creature forms the type. It is undoubtedly 

 allied to the European Langelandia, but differs from it in having 

 distinct eyes ; Chorasus, a New Zealand genus, has 4-jointed tarsi. 



1713. L. COStalus, n.s. Elongate, somewhat convex, covered 

 with a scale-like, sappy deposit ; fuscous, tarsi and antennae fulvous. 



Head half the width of thorax, bearing two carinae, which pro- 

 ceed from the eyes and nearly converge in front. Antenna rather 

 short, basal joint largest, about as long as broad, reddish ; second of 

 similar form, but at least one-third smaller ; third rather shorter 

 than fourth, slender ; fourth and fifth nearly equal, longer than the 

 contiguous ones ; sixth and seventh equal, slightly shorter and 

 broader than the preceding two ; eighth and ninth a little broader 

 than seventh, narrowed basally ; tenth somewhat cup-shaped, thrice 

 the bulk of the ninth ; eleventh as broad as but one-half longer 

 than tenth, apparently obtusely notched at the extremity. Pro- 

 thorax transversal, rounded laterally towards the front and much 

 narrowed behind, posterior angles rectangular, the anterior distant 

 from the eyes, base medially incurved, middle of apex truncate,
