ABACETUS SEKVITULUS, n. sp. 



Black, with the three basal joints of the antennae reddish, the 

 joints are infuscate, the anterior legs are more reddish than the 

 intermediate and posterior ones, which are piceous ; the elytra 

 have a slight iridescent sheen ; frontal impressions somewhat 

 short, arcuate ; prothorax as long as broad, widest at about the 

 median part, arcuate-ampliate laterally from the anterior angle to- 

 two-thirds of the length, and sloping thence without sinuation to the 

 outer basal angle, which is sharp, but not projecting, the outer 

 margin is slightly piceous-red, plainly reflexed, the lateral sulcus. 

 runs from the apical to the basal angle, and is continued as an 

 occasionally faint, impressed line reaching the basal sulcus the base 

 of which is situated nearer the outer margin than to the median 

 impressed line, the supra-basal space between the two is closely 

 punctulate, the posterior part of the sides is not depressed ; elytra 

 oblong, intervals convex with the striae impunctate, the setigerous 

 puncture of the third interval median ; last abdominal segment bi- 

 or quadri-setigerous according to sexes ; the sides of the segments, 

 the metasternum and the metasternal episterna are plainly punctate, 

 the latter are longer externally than the anterior border ; posterior 

 tarsi pluri-sulcate ; fifth joint glabrous underneath. 



The general facies is not unlike that of A. clarus, which belongs 

 to another group of the genus, but the posterior part of the prothorax 

 is straighter, and not sinuate.

ABACETUS MALVEKNENSIS, 11. sp. 



Black, very shiny with the palpi, the legs and the three basal 

 antennal joints red, the other antennal joints are rufescent ; head 

 with the frontal impressions short, narrow but deep, and arcuate ; 

 prothorax longer than broad, slightly arcuate laterally from the 

 anterior angle to nearly the median part, sub-diagonally attenuated 

 thence to the base, the sharp angle of which projects slightly, making 

 the part of the outer margin adjoining it appear as if slightly sinuated 

 immediately above it, the lateral margin is sharp, slightly reflexed,
