Habitat Gomeram, a W. D. Crotch semel captus. 



The only specimen which I have seen of this Oihius was captured 

 by Dr. Crotch, during the spring of 1862, in Gomera. It is well 

 distinguished by its black hue, extremely short, piceous, finely and 

 sparingly punctulated elytra, rather thick oblong head, faintly sub- 

 metallic abdomen, and piceo-testaceous limbs. In its minute eyes 

 and general fades it has a good deal in common with the Madeiran 

 0. Jansoni ; but it is a smaller insect, with the limbs shorter, and 

 the elytra much more finely sculptured and less developed. 



887. Othius pMlonthoides, n. sp. 

 0. prsecedente minor, angustior, subnitidior ; elytris pallidioribus (sc. 

 infuscato-testaceis), minus abbreviatis et profuudius punctatis ; 

 capite subminore, utrinque \'ix parcius punctato, oculis paulo ma- 

 joribus ; abdomine etiam levins subasperato-punctulato, hand me- 

 tallico-tincto ; antennis pedibusque sensim brevioribus, pallidiori- 

 bus. — Long. Corp. lin. 2^. 



Habitat Canariam Grandem, in regione El Monte semel repertus. 



This little Othius is of about the size and general outline of the 

 larger examples of the Philonthus nigritulus ; and it may be known 

 from the preceding species by being smaller and narrower, with its 

 limbs rather shorter and paler, and with its elytra liliewise paler, 

 somewhat less abbreviated, and much more coarsely punctured. Its 

 head, also, is relativehj a trifle smaller, its eyes are not quite so di- 

 minutive, and its abdomen is even more finely punctured still and 

 apparently free from the slightest metallic lustre. The unique ex- 

 ample described from I captured, during the spring of 1858, in the 

 region of El Monte in Grand Canary.
