STENID.E. HESPEROPHILUS. 309 



punctured: abdomen minutely punctured: femora dusky, or pale ochreous; 

 tibiae ochreous-red ; tarsi pale ochreous : antennae pale rufous : mandibles 

 the same. 

 Female without the thoracic horn, and the head armed with the two short 

 tubercles only. 



This rare species I have dedicated to my friend the Rev. G. T. 

 Rudd, who captured it in " Coatham Marshes, Yorkshire." 



Genus DXXXI. — Hesperophilus* mihi. 



Antenna; geniculated, slightly thickened at the apex, the basal joint long, 

 clavate, the two following short, obconic, the remainder short, tiirbinated, 

 terminal one obtuse. Palpi unequal; maxillary with the third joint 

 stout, elliptic, terminal slender elongate, somewhat subulated : labrum 

 transverse : mandibles slender, curved, acute : body linear, cylindric : head 

 unarmed, porrect, unequal in front : eyes small, prominent : thorax scuti- 

 form, unarmed : elytra s'omewhat remote, convex, the shoulders prominent, 

 the apex truncate : legs short, stout : tihiw entire, four anterior compressed, 

 denticulate-pectinate on the outer edge, the apex with short spurs : tai^si 

 slendei-, retractile, quadriarticulate, the terminal joint longest, pilose be- 

 neath. 



The simple head and thorax of the insects of this genus, exclusively 

 of their smaller size and the minute dissimilarities in the structure of 

 the trophi, antennae, &c.; the less remote elytra, simpler legs, &c. 

 distinguish them from the Bledii, with which they have hitherto been 

 associated: — the species are sometimes found in great abundance, 

 and fly gregariously in the evening, whence their appellation. 



Sp. 1. fracticornis. Niger, thorace unisulcato, profunde punctata, antennis hasi 



pedibusque riifis. (Long. corp. 2§ lin.)
