140 Mr. T. V. Wollaston on certain Coleopterous Insects 



The diminutive insect from which the above characters have been 

 drawn has so much the resemblance of a minute Mycetcea, that it 

 was not until I had examined it attentively that I perceived its 

 distinctions. Its maxilla and under-lip I have unfortunately not 

 succeeded (in the single specimen which I broke up) in securing ; 

 but its antenna), upper-lip, mandibles, maxillary-palpi and feet, I 

 have mounted carefully in balsam, and have thoroughly inspected. 

 In all these details it offers slight differences from the corresponding 

 ones both of Mycetcea and Symbiotes, to which it is closely allied ; 

 but in the structure of its much more abbreviated antenna?, which 

 are 10-arriculatc and with a 2-jointed club, it recedes from them 

 altogether, — the antennas of both of those genera having eleven 

 joints, with a 3-articulated club.

Several examples of this interesting little insect were captured by 

 Mr. Bcwickc " out of an ants' nest, in a grass-field above the Botanic 

 Garden," at Cape Town.

Cis subomatus, n. sp. 



C. lineari-cyliadricus angustus, piceus, nitidus, dense punctidatus et 

 (oculo valde armato) pilis minutissimis brevissiniis cinereis parce 

 irroratus; capite magno subporrecto, apice subtruncato incrassato 

 marginato; prothorace subsequali, subquadxato, antice vix produeto, ad 

 latera (et minus postice) marginato ; elytris parallelis, vix subrugulosis 

 (punctis hand longitudinaliter dispositis), versus humeros et apicem 

 pins minus obsenre snbrufescentiorihus ; antennis dilute testaceis, clava 

 infuscata; pedibus rufo-ferrugineis.

The present Cis has. to me at least, a peculiar interest, from it 

 being of precisely the same type as the Madeiran C. Wollastonii, of
