Exhibitions, dc. 



Mr. F. P. Pascoe exhibited the aerial roots of an orchid (Sarcmithus 

 Parishii) which greatly resembled caterpillars. 



Mr. Pascoe also exhibited a new genus and species of ColydiidcB, 

 remarkable in that its eyes were beset with broad erect scales arising 

 between the facets, a character of rare occurrence among the Coleoptera. It 

 is from North Borneo, and is described by Mr. Pascoe as follows : — 



Optis, Pascoe. 

 Corpus peltiforme. Oculi prominuli, squamiferi. Antennse 1 1-articu- 

 latae ; funiculus subfiliformis, clava rotundata, biarticulata ; sulci antennarii 

 obliqui. Tibife subfusifornies, spinis terniinalibus nullis ; tarsi articulis 

 tribis primis sequalibus. Coxge posticfe baud approximatfe. Abdomen 

 segmentis longitudine sequalibus ; processus intercoxalis triangularis. 



Optis bicarinata, Pascoe. 

 O. lata, subparallela, indumento albo induta; caput trausversum exca- 

 vatum sed in medio pauUo elevatum : prothorax brevis, versus apicem 

 bituberculatus ; scutellum nitide nigrum, transversum ; elytra postice late 

 rotundata, singulojuxta suturam carina elevata — antice excurvata, postice 

 abrupte terminata-instructa ; pedes rufo-testacei, tibiae margins exteriore 

 squamoso-fimbriatfe. Long. 4 mm. ; lat. 2^ mm. 



The structural characters of Optis, except the eyes, are almost the same 

 as those of Endophlceus, but the posterior coxae are not approximate, and 

 the last joint of the fuuicle is scarcely broader than the preceding one ; 

 this character is so far important that in E. flexuosus, Sol., it is so broad as 

 to form the basal joint of the club, which thus becomes three-jointed. In 

 Gay's ' Chili ' the species is represented as being heteromerous (for this 

 Lacordaire would refer it to Bolitophagus), but they are clearly four-jointed 

 in my specimens. The type of Optis is broader and more convex than
