674 MR. E. J. MIERS ON A COLLECTION OF [June 19, 



I am in some doubt whether this species be the C. misanthropus 

 of Risso and of M. Milne-Edwards, who apparently copied Risso's 

 description ; but it is almost certainly the species figured under this 

 name by Roux. It differs only in having the tarsi striped with red 

 upon a white instead of a blue ground ; but this latter colour is in all 

 probability CTauescent ; indeed in one or two specimens from the 

 Spanish coast in the collection of the British Museum, some very 

 faint traces of the blue coloration are still discernible. 



Clihanarms oculatus, Fabricius, as described by M. Milne-Edwards, 

 appears to differ in having the tarsi much shorter than the penulti- 

 mate joint. They are coloured with longitudinal red and yellow lines,

The colour of the specimens in the collection is light brown, length 

 62 lines, breadth 3 hues. The lateral margins of the coxse and 

 segments of the tail are fringed with very short hairs. This species 

 appears to be common in the Mediterranean region, having been 

 recorded from Egypt, Algeria, Gibraltar, Lesina, &c. 



The specimens I refer to Tj/los latreillei differ from specimens of 

 T. capensis, Krauss, in the British-Museum collection, from Simon's 

 Bay, South Africa, in their much smaller size (the largest specimen 

 of T. capensis is one inch in length), and in the form of the epimeral 

 piece or coxa of the sixth pair of legs ; in T. latreillei the postero- 

 lateral angle of this joint is rounded ; in T. capensis the posterior margin 

 is straight, and forms a right angle with the posterior margin. More- 

 over in T. capensis the segments are nearly smooth, or only very 

 finely granulated; in T. latreillei they are rather strongly punctu- 

 lated and rugose. In both species the postero-lateral angle of the 

 coxa of the last pair of legs is acute. 



Tylos granulatus, sp. n. (Plate LXIX. fig. 2.) 

 Convex, coarsely granulated, the granules on the dorsal surface of 

 the body separated by linear smooth intervening spaces ; the process 

 of the epistonia separating the basal joints of the antennae, and the 

 peduncles of the antennae themselves, very strongly granulated. 

 Postero-lateral angles of the first segment of the body strongly 

 flexed backward and acute. Terminal segment of the tail trans-
