than the prothorax at its widest part, the impunctate striae are deep, 

 the intervals moderately convex, the puncture on the side of the 

 third interval is situated slightly in front of the median part, under- 

 side impunctate, metasternal episterna longer than broad ; the sulci 

 of the hind tibiae are plain, without being very deep, the hind tarsi 

 are not sulcate, and the fifth joint is glabrous underneath ; last 

 abdominal segment with two or four setigerous punctures according 

 to the sex. 



This species resembles A. pygm&us, Bohem., which is, however, 

 metallic green with the legs red, but the prothorax is not so much 

 narrowed behind, nor is it sinuate above the basal angle.

ABACETUS EVULSUS, n. sp. 



Bronze-green, slightly less green on the elytra than on the pro- 

 thorax ; femora infuscate, tibiae flavescent except at apex and base, 

 antennae black with the three basal joints red ; frontal sulci as in the 

 preceding species ; prothorax cordate, ampliated laterally, constricted 

 and slightly sinuate in the posterior part, but with the base very 

 little narrower than the apex, the lateral sulcus is narrow and con- 

 nected with the basal one by a still narrower impressed line, but is 

 otherwise as in A. discrepaus ; the elytra are oblong, the intervals 

 plane, the puncture on the side of the third interval is ante-median ; 

 the under side and legs are as in A. discrepans. 



The nearest ally of this species is A. pygmaus, Boh., but the 

 prothorax is more ampliated laterally, the intervals of the elytra are 

 quite plane, and the puncture on the third interval is situated only 

 slightly past the first third of the length, instead of being about 

 median as in A. pygmcvus. 



Length 5-5^- mm. ; width 2-2J- mm.

ABACETUS SHILOUVANUS, n. sp. 



Blackish-bronze with the three basal joints of the antennas red, 

 the other joints are deep fuscous ; the femora almost black, the tibiae 

 and tarsi flavescent ; the head and prothorax are as in A. eviilsus, 

 but the elytra are more elongated, the humeral part is less rounded, 

 and not wider past the shoulder than the prothorax at its widest 

 point, they are also slightly sinuate laterally, the striae are deep, the
