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



The diminutive insect from which the above characters have been 

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

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

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

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

 but its antennae, 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 Mycet(xa and Si/mbiotes, to which it is closely allied ; 

 but in the structure of its much more abbreviated antennae, which 

 are 10-ardculate and with a 2-jointed chib, it recedes from them 

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

 joints, with a 3-articulated club.

.Several examples of this interesting little insect were captured by 

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

 Garden," at Cape Town.

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

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