47!2 M. JACOBY 



closely punctured, black; elytra with a short but deep depression 

 below the base, moderately strongly punctate-striate, black, the 

 shoulders with a narrow subquadrate, elongate fulvous spot, 

 under side and legs piceous or black, prosternum subquadrate, 

 strongly punctured, claws bifid. 



Ighibirei. 



Of this species a great many specimens were obtained, I have 

 however taken the spotted form for the type although the va- 

 rieties are much more numerously represented, structural dif- 

 ferences there are none between them but the species may pe- 

 rhaps best be recognized by the strong and close punctuation 

 of the head in connection w-ith the well defined or separated 

 clypeus. In R. 4-puslulata Jac. a closely allied species, the head 

 is finely punctured and the clypeus is not separated ; R, pietà 

 Baly has also a smooth, impunctate head and differently marked 

 elytra. I may further add, that the male in the present species 

 has the anterior tibiae strongly dilated and slightly flexuose. 



4. tilxyparicia riviilavis, sp. n. 



Black, labrum and the basal joints of the antennae fulvous, 

 head opaque, thorax strongly transverse, finely and rather clo- 

 sely punctured, the punctures of equal size, elytra with deep 

 basal depression, strongly punctured anteriorly, finely so towards 

 the apex, femora unarmed. 



Length 4 millim. 



Head opaque, finely punctured at the vertex, the middle por- 

 tion distinctly bilobed, episteme separated from the face, more 

 strongly punctured, its anterior margin nearly straight, labrum 

 fulvous, antennae either entirely fulvous or the basal three joints 

 only of that colour, the rest piceous, thorax more than twice 

 as broad as long, the sides rounded, rather strongly so at the 

 middle, the angles acute, the disc finely, evenly and rather clo- 

 sely punctured, the middle portion rather more distantly pun- 

 ctate, scutellum oblong, smooth, elytra with a short but deep
