DESCKIPTION OF A NEW MAEITIME FLY BELONaiNG TO THE 

 FAMILY SCATOMYZIDES, FALLEN. 



BY R. n. MEADE. 



The following Dipteron occupies a position intermediate between 

 those in the genera Scatopha(ja and Cordi/lura. It has the elongated 

 horny proboscis with the numerous vibrissse, o£ the species in the 

 former genus, and the sub-cylindrical, incurved, clubbed male abdo- 

 men of those in the latter. 



I propose to place it in a new genus, whicb I shall call Ceratino- 

 stoma. Schiner describes a new Cordylura (lurida), which, from his 

 account, should also be placed in the new genus.

C. MARITIMUM, Sp. n. 



Plumheo-nigricans opaciim, thorace olivario-fusco pollinoso, suh-striato ; paJpis 

 pallidis, hreviter nigro-setosis ; proboscide nigro-picea ; pedibus plumbeis, tibiis 

 posticis iritus villosis, tarsis omnibus subtiis falvo-hirtis. Long., (? e^ $ , 8 vim.

 tawny hairs ; frontal bristles extending in a single row along each side of the 

 frontal stripe, from the vertex to the base of the antennae ; those in the posterior 

 half of each row turning outwards, and those in the front half inwards ; oral setae 

 rather short, six to eight in number on each side ; antennae black, the first joint 

 abbreviated, the second somewhat elongated, having a reddisli-brown or grey tinge, 

 with white reflections on the distal margin, and armed with short black bristles ; the

 long as the second ; arista short and mostly somewhat geniculated, the first joint
