68 Mr. David Sharp on the 



pale yellow, only moderately long, the femora rather 

 stout. 



Two specimens (a third I unfortunately lost) ; under 

 dead leaves at Maiyasama, Hiogo. 



Mesunius, nov. gen. Pcederini (juxta Sunium locandus). 



Labrum medio quadridenticulatuni. 



Palpi maxillares articulo ultimo vix distinguendo. 



Tarsi articulo 4° bilobo. 



Mandibles very elongate and slender, the basal half of 

 each with three teeth, the upper one elongate, the lower 

 one very short. Labrum very broad, in the middle Avitli 

 a notch, on each side of which is a distinctly projecting 

 tooth, and outside this is another tooth separated by a 

 shallow notch from the other. Maxillary palpi long and 

 slender, 2nd joint very elongate and slender, 3rd elongate 

 and but little thickened, ratlier shorter than the second, 

 4th joint invisible. Antennfe slender, not genicvdate, Avith 

 the two basal joints (more particularly the 1st) stouter 

 than the others. Head with a narrow neck. Eyes small. 

 Thorax with the sides rounded and not ano-ulate. Hind 

 body dilated. Posterior tarsi with the basal joint elongate, 

 the 4th joint bilobed. 



The insect for which I establish this genus is clearly 

 allied to the Sanius jiulchcr of Aube. In Von Heyden's 

 " Entomologische Reise nach dem sud. Spanien," the 

 S. pulcher (or a closely allied species) is figured as belong- 

 ing to the genus Mecognnthus, Woll. This, however, is 

 an error. The S. pulcher, Aube, belongs to a genus quite 

 distinct from Mecognathus, Woll., and possesses indeed- 

 all the characters I have assigned above to the genus 

 Mesunius, in which genus it should therefore be placed 

 for the present, though I believe the Algerian insect 

 will ultimately prove to be generically distinct from the 

 Japanese one. 



128. Mesunius Wollastoni,w.&^. Niger, fortiter punc- 

 tatus, tenuissime pubescens, antennis pedibusque testaceis, 

 ilUs basi rufis, prothorace basi medio bi-impresso ; elytris 

 hoc brevioribus. Loner. 3 lin. 



AntennfB rather shorter than head and thorax, yellow, 

 with the basal joints redder than the others ; 3rd joint very 

 slender, twice as long as 2nd, 4—10 each distinctly 

 shorter than its predecessor, 10th joint slender, three times
