new Species of Cyp'iogastra. 491 



C. venfricosa lias usually two vittic at the apox of the elytra; 

 the sutuial ouc, however, is sometimes, thou^^h rarely, absent. 

 The ^fuseum speeimen has onl\' one lateral yellow vitta at 

 the apex of the elytra. I can ouly suppose that Kerrcmans 

 has eomparcd aterriina with the variety of ventricosa, in 

 which the sutural vitta is al)sent, or that in aterrhna the 

 sntural vitta is sometimes absent as in ventricosa. They are 

 hardly likely to be distinet species. 



AVhile detcrminiiii^ this s[)eeies, I have noticed the two 

 following spccieSj which appear to be undescribed. 



Cyphogastra bicolor, sp. n. 



Capite cyaueo ; thoraco la;te cyaneo-viridi, utrinque fovea magna 

 flavo-pilosa ; elytris la^te purpureo-cu])reis, evidenter punctulatis, 

 ad apiccm cyaneis ; corporo suLtus viridi, flavo-pulvcruleuti. 



Long. 27, lat. 8-5 mm. 



Hah. S.E. New duinea. 



Head very dark blue, with a little dark green near the 

 eyes : convex with a rather small, deep, elliptical fovea 

 between the eyes. Thorax bright bluish green, the anterior 

 angulation of the sides very obtuse, not prominent, not 

 thickened ; the sides subparallel, only very slightly widening 

 towards the hind angles, which are very slightly ])rominent, 

 convex and coarsely punctured. The median channel 

 moderately deep, with a single line of small [junetures. The 

 disk with few punctures. The lateral impression large, 

 shallow, leaving a small sub-equilateral area at the hind 

 angles, merging in front of the lateral angulation into two 

 small impressions; all the impressed parts filled with yellow 

 powder. Elytra bright coppery with a slight purple shade, 

 distinctly but not strongly punctured (the punctures at the 

 base rather larger), rather broader behind the middle than 

 at the base, then giadually narrowed towards the apex, the 

 apex very slightly Avidened and gently compressed, denti- 

 culate, the sutural angle acute. The apex is dark blue, 

 bordered with green basally. 



Hody beneath bright golden green, more or less clothed 

 with yellow powder, which forms spots on the abdomen. 



There is nothing in the British Museum with which I can 

 compare this. The very wide shallow lateral impressions 

 leave only a very small triangular space at the hind angles, 



I propose placing it near C apicalis, Kerrem., but the 

 elytra are slightly more pisciform at apex.
