Syria ; it is closely cnnnected with Homalofa, but has more the facies 

 of Cdlodera ; Mulsant and Eey place it at the head of their fourth 

 division of the Myrmedoniaires, the Honialotates : our two species occur 

 in moss, haystack refuse, in sandpits, near banks of rivers, &c. 



Length 2| mm. ; last joint of antennae very long, tenth 



much longt'i- than ninth C. obscueus, Grav. 



Length 4— i| mm. j last joint of autennse moderately long, 



tenth about equal to niuth C. EiGiDicoENis, Er. 



C. oljscurus, Grav. Dull black or pitchy brown with the elytra 

 lighter, finely pubescent, head rather large nearly as broad as thorax, 

 antennae very long, reaching nearly to the apex of the elytra, rather 

 more thickened in the female than in the male ; the latter sex has the 

 tenth joint very long, and joints 6-9 moderately transverse ; in the 

 .former the tenth is less elongate, and joints 6-9 more strongly trans- 

 verse ; the last joint is also longer in the male than in the female ; thorax 

 about as long as broad, plainly narrower than elytra, obsoletely punc- 

 tured ; elytra a little longer than thorax, thickly punctured ; hind body 

 parallel-sided until near apex, finely punctured towards base, almost 

 smooth behind ; legs lighter or darker testaceous. L. 2f mm. 



The sexual dilferences of the hind body in this species are slight, 

 but the sexes differ very much in general appearance, the females that 

 I have seen appearing to be somewhat broader and stouter with broader 

 and squarer thorax and elytra, and of a browner colour ; the antennae 

 also differ considerably, as will be seen from the above description; in 

 fact they might be taken for different species. 



In moss, haystack refuse, near rivers, in sandpits, &c. ; local, but not uncommon in 

 some localities, and widely distributed; London district, rather common ; Tonbridge j 

 Hastings ; Brighton ; Lewes ; Knowle, near Birmingham ; Lincoln ; Scarborough ; 

 Manchester; Liverpool; Northumberland district; Scotland, local, Lowlands, Forth 

 iiud Solway districts ; Ireland, Portmarnock and near Belfast; it is usually found 

 most plentifully in early spring : Haliday remarks that he took it abundantly at Holy- 

 wood, B-^lfast, under the shelter of furze-bushes on the fresh grass of sunny banks at 

 this time of year. 



C> rig-idicornis, Er. ( ^J unicarinatus, Fairm.). Much larger than 

 the preceding species, and very different from it in general appearance ; 

 pitchy black, rather shining, with the elytra chestnut-brown and the 

 apex of hind body testaceous ; head, as a rule, distinctly narrower than 

 thorax, antennae long, plainly longer than head and thorax, gradually 

 thickened towards apex, entirely reddish testaceous, penultimate joints 

 not transverse, tenth about equal to ninth, eleventh as long as the two 

 preceding ; thorax subquadrate, a little broader than long, slightly 

 narrower at base than elytra, thickly and somewhat asperately punctured ; 

 elytra about as long as, or a little longer than, thorax, and more plainly 

 sculptured ; hind body thickly and finely punctured in front, almost 

 smooth behind ; legs testaceous. L. i-il mm.
