the apical fourth. The postmedian patch is large, rounded in front, almost straight 

 behind, sinuate in front on the suture, and produced some distance backwards 

 behind. The midtibia of the S has no apical tooth.

? . Similis A. geminae, pronoto longitndinaliter levissime bi-irnpresso, vittis 

 lateralibus interrupts, elytris subtilius punctato-striatis, ad suturam magis depressis, 

 maculis dorsalibns minoribus, postmediana communi cruciformi.

Perhaps a subspecies of A. gemina, and to some extent intermediate between 

 that species and A. vicina. The prothorax agrees with that of A. gemina in 

 having three vittae, but the lateral ones are interrupted ; the depressions of the 

 pronotum are less distinct than in A. vicina, and the puncturation is very incon- 

 spicuous. The postmedian sutural patch of the elytra is smaller than in the two 

 previous species, and produced forward as well as backward on the suture, some- 

 what resembling a flying bird ; there is a rounded spot at one-third of the lateral 

 margin ; the dorsal spots are all small. 



Key to the species of Apolecta : 



A. Intercoxal process of mesosternum not convex in the centre, 

 a. Pronotum punctated, at least laterally. 

 a 1 . Meso-metasterna distinctly punctated.

 apical declivity. 

 a 3 . Elytrum in middle at most with sharply defined rounded black 

 spot.
