110 , Mr. A. Murray on Coleoptera from Old Calabar. 
‘Two or three specimens. 
I have named this species after Mr. Edward Saunders, in 
recognition of the services he has already done in rescuing a 
portion of the Buprestide from the confusion in which they 
lay—services which all entomologists must hope will be con- 
tinued and extended to other groups. 
MycHOMMATUS*, nov. gen. 
Caput parum excavatum, secus marginem internum oculorum 
canaliculatum; epistoma antice parum emarginatum. Anten- 
ne breves, articulis primis, secundis et tertiis obconicis, pri- 
mis majoribus, secundis et tertiis eequalibus, ceteris fortiter 
serratis, transversis, undecimis emarginato-truncatis.  Pro- 
thorax depressus, brevis, transversalis, lateribus canaliculatis, 
postice latior et medio lobato. Scutellum sat magnum, 
planum, transversum pentagonale, antice arcuatum. Hlytra 
elongata, disco plano et subdepresso, a basi ad apicem gra- 
datim attenuata, apice parum expanso, rotundatim truncato, 
dentibus fimbriato. Ischia postica margine antico excavato, 
margine libero late curvatim emarginato. Tibiz posticee 
extus pilo fimbriate, anticee simplices; tarsi sat robusti, 
lamellis omnes instructi, articulis brevibus, postici articulo 
primo parum elongato, ceteri fere equales: unguiculi sat 
fortes, breviter fissis. Metasternum antice protensum, 
medio profunde emarginatum.  Prosternum depressum, 
antice truncatum, postice projiciens. Corpus elongatum, 
depressum, cuneatum. 
This genus has the cuneiform facies of Stenogaster, dif- 
fering apparently only in being smooth and shining, instead 
of unequal and marbled with irregular pubescence, &e.; and 
Stenogaster bemg wholly Brazilian, at first I regarded it as 
another instance of the presence of a South-American form on 
the west coast of Africa; but the presence of lamelle on all its 
tarsi removes it from that category. Its facies, however, seems 
to require the establishment of a new genus for its reception, 
the shortness of the tarsi preventing its Beis a place among 
the Agrili, which it most resembles in form 
Mychommatus cyaneus. Pl. VIII. fig. 3 
Nitidissimus, et supra et subtus lete cyancus, elytris violaceo- 
cyanels ; ; capite leviter sparsim punctato ; prothorace parum 
fortius punctato, disco fere impunctato, angulis posticis sub- 
rectis ; scutello impunctato ; elytris sparsim 1 leviter punctatis,

the inner margin of the eye.
