named, rounded, elytra fmely putictate-striate, the punctures dis- 

 tinct at the base and apex, femora with a strong tooth in the maie. 



Length 6 mill. 



Head nearly impunctate or with a few minute punctures, the epis- 

 tome not separated from the face, its anterior margin concave at 

 the middle, labrum and mandibles fulvous, apex of the latter black, 

 antennse with the lower five joints fulvous, the foUowing four black, 

 the apical joints wanting, the first and second strongly thickened at 

 the apex, the third shorter than the fourth but twice as long as the 

 second joint, the seventh and the following two distinclly widened; 

 thorax scarcely twice as broad as long, the sides evenly rounded, the 

 dise scarcely perceptibly and very sparingly punctured, scutellum 

 impunctate; elytra wider at the base than the thorax, with a very 

 feeble dépression below the base, finely punctate-striate, the punc- 

 tures rather larger at the sides, distinct at the base and apex; below 

 fulvous, the tibise rather darker, the tarsi black. 



Hah. Diego Suarez. 



This Syagrus of which two spécimens are before me seeras most 

 nearly allied to S. attelaboides Fairm. also from Madagascar but 

 that species is described as of much smaller size, with a finely and 

 closely punctured thorax and with the elytral punctures wanting at 

 the base and the apex. (The colour of the antennge is not given by 

 the author.) The female of the présent species bas the posterior 

 femora distinctly toothed only, the others bave but a very small 

 one. 



S. geniculatus Lef. seems very closely allied but difïers in the 

 colour of the antenna^, the finely punctured thorax, the transversely 

 impressed elytra and the colour of the tarsi, the locality is likewise 

 quite différent (W. Africa.) 



RHEMBASTUS G^RULEIPENNIS n. sp. 



Fulvous, the apical joints of the antennse black, head and thorax 

 nearly impunctate, elytra metallic dark blue, strongly punctate- 

 striate, the interstices slightly convex, sparingly punctured. 



Length 2 1/2 mill. 



Head impunctate, with a short central longitudinal groove, cly- 

 peus separated from the face by a shallow transverse groove, sub- 

 quadrate, with a few punctures, antennse slender, the lower six 

 joints and the base of the seventh flavous, the others black, the 

 second joint about one third shorter than the third one; thorax 

 subcylindrical, the sides feebly but distinctly rounded, the anterior 

 angles thickened, the surface impressed with a few minute punc- 

 tures, only visible under a strong lens, fulvous, scutellum fulvous, 

 elytra with a shallow dépression below the base, very strongly
