narrower, leaving the latéral parts ot' the abdomen and a great 

 part of the coriuna uncovered, and slightly narrowing backward at 

 the very base with short frena, then parallel through a short 

 distance before being moderately amphated. In Caenina{he scutel- 

 lum is strongly amphated from the very base, without frena, and 

 covering a greater part of the corium and the posterior part of the 

 abdomen. Sepontia is known only from Africa (in the eastern part 

 of which its only species is common); to Cœnina belong the Asiatic 

 and Australian species hitherto placed in Sepontia, excepling 

 S. auslralis Schout. which probably is a Neostollia. As the name 

 Cœnina is preoccupied (Felder, Lepidoptera, 1861), I propose for 

 Walker's genus the name Spermatodes.

This very distinct species is the smallest Pentatomoid bug 

 hitherto known from the Old World. (From Venezuela I know a 

 still smaller undescribed Pentatomid).
