and Dr. Crotch, iii Palma by Mr. Gray, and in Teneriffe by Dr. Crotch 

 and the Barao do Castcllo de Paiva. It occurs principally in hot and 

 dry spots of a rather low elevation. 



Its somewhat less parallel outline and short, deeply punctured, 

 anteriorly narrower prothorax, in conjunction with its larger eyes, 

 rounder and less prominent genae, and more pubescent (though tm- 

 scaly) surface, will, apart from the curious, backwardly-directed 

 bristles with which the underside of the basal joint of its interme- 

 diate male feet are pectinated (a structure which I have not seen 

 noticed, except in my ' Ins. Mad.'), at once separate the 0. hisjiidum 

 from the other Ojpatra here enumerated.

0. oblongum, subcalvum (subtilissime, brevissime et parcissime pu- 

 bescens), sed plus minus lutoso- squamosum ; genis ante oculos 

 valde exstantibus, rotundato-angulatis ; prothorace parcc ct raiimto 

 granulato (vix punctato) et subtilissime ruguloso, ante medium 

 lato, ad latera valde rotundato, angulis anticis acutis, postieis acute

 gulosis ; antennis pedibusque clare rufo-ferrugineis. — Long. corp.

This Opatrum, which has been observed hitherto only in Lanzarote 

 and Fuerteventura, is smaller than any of the preceding ones, and 

 much less pubescent — being merely besprinkled sparimjly with ex- 

 cessively diminutive decumbent setae, though often densely covered 

 with mud-hke scales ; its prothorax is of a totally different shape — ■ 

 being wide in front, greatly rounded at the sides, and with the ex- 

 treme hinder angles acutely prominent ; its genae project considerably, 

 in front of either eye ; and its legs are of a more or less clear rufo- 

 ferruginous hue. It closely resembles a species which I have received, 

 from Nice, as the " O.pygmceum, Dejean " : but its genae are a little 

 less obtuse at the apex ; its prothorax has the anterior angles some- 

 what more porrect and acute, and the posterior ones conspicuously 

 less prominent ; its elytra are more coarsely punctate-striated, with 

 their humeral angles much rounder (or less of right angles) ; and its 

 wings, instead of being powerfxilly developed, are very small and 

 rudimentary. I have taken it in dry, calcareous, and sandy spots, 

 of a low elevation, in Lanzarote and Fuerteventura, particularly at a
