110 Mr. A. Murray on Coleojptera 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 Buprestidse 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- 

 nae breveSj articulis primis, secundis et tertiis obconicis, pri- 

 mis majoribus, secundis et tertiis gequalibus, 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. Elytra 

 elongata, disco piano 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. Tibiae posticse 

 extus pilo fimbriatge, anticas simplices ; tarsi sat robusti, 

 lamellis omnes instructi, articulis brevibus, postici articulo 

 primo parum elongato, ceteri fere gequales : 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, &c. ; and 

 *Stenog aster being 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 lamellae 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 taking a place among 

 the Agrilij which it most resembles in form. 



Mychommatus cyaneus. PI. VIII. fig. 3. 



Nitidissimus, et supra et subtus kete cyaneus, elytris violaceo- 

 cyaneis ; capite leviter sparsim punctato ; prothorace parum 

 fortius punctato, disco fere impunctato, angulis posticis sub- 

 rectis ; scutello impunctato ; elytris sparsim leviter punctatis, 



* From iivxh, « recess^ and ofxixa, the eye, in allusion to the canal along 

 the inner margin of the eye.
