tween the two basal segments of the ventral surface of the abdo- 
men; this line is usually obsolete or only indistinct in Odontota.

This beautiful species is the most common of the genus, and 
found in most collections ; it is broader than any of the others, 
with the exception of M. rubroguttata, which insect approaches it 
very closely in form, but is less flattened above. 
Sp. 2. Metaxycera rubroguttata. 
Obcuneiformis, dorso depressa, late rufo-testacea, subnitida ; 
vertice postice, thoracisque plaga magna discoidali nigro- 
piceis; antennis elytrisque nigris, his a basi ad apicem perpa- 
rum ampliatis, apice rotundatis, utrisque margine humerali 
pustulisque quinque, harum tribus prope suturam, prima 
infra basim, secunda prope medium, tertiaque apicem versus, 
duabusque intra marginem exteriorem, prima infra humerum, 
secunda prope angulum posticum positis, rufo-testaceis.

The four hinder spots on each elytron are confluent in pairs, 
and form two oblique fascize on the disc ; thorax transverse, sides 
nearly straight and parallel behind, obliquely narrowed in frout ; 
upper surface irregularly excavated, opaque, irregularly but not 
closely punctured, middle of disc with an indistinct longitudinal 
groove; scutellum black, its apex rufous. 
This species closely resembles in form AI. purpurata, Guér. ; it 
is, however, less depressed, less coarsely punctured, more regu- 
larly rounded both at the hinder angles and apex, and the arrange- 
ment of the spots on the elytra is different.

Olivier describes this species as having a black scutellum; it 
varies, however, greatly in this respect, some specimens having 
the scutellum more or less stained with rufous, others entirely red.
