more or less of the posterior half, infiiscate. Antennae, mouth- 

 parts and legs reddish-testaceous. Length .3 mm. 



Allied to M. opacellus Fauv., but smaller and narrower, the 

 antennae more slender, the vertex of the head a little shining, the 

 sculpture consisting of close simple punctures not at all rugulose 

 on the disc, but only granular at the base and temples. Head 

 large, transversely quadrate, the posteiior angles rounded, the base 

 feebly emarginate; the eyes moderate; sculptiu:e on the disc con- 

 sisting of modei-ately large close punctures, at the sides, base and 

 temples of small granules. Antennae slender, the 2nd joint a little 

 shorter than the 3rd, the 4th to the 6th all a little longer than 

 broad, gradually decreasing in length, the 7th to the lOtli about 

 as long as broad. Thorax scarcely broader than long, the sides 

 narrowed from the apex to the base and setose; sculpture consist- 

 ing of a fine close granulation, the disc with a trace of a smooth 

 median line. Elytra longer and a little broader than the thorax, 

 longer than broad, with a close (but not so close as on the thorax) 

 granular sculpture; pubescence fine and yellow. Abdomen closely 

 and finely punctured throughout; pubescence close, yellow. 



(J. Seventh ventral segment with a deep emargination ; sixth 

 ventral segment with a broad, but not deep emargination.

26 {a). Medon (Charichirus) terminalis, n. sp. 



Black, opaque (greasy lustre onlj'), the posterior third of the 

 elytra dull reddish. Antennae black, the last three or four joints 

 reddish-testaceous; legs pitchy. Length 5-5 mm. 



Exactly similar in build and puncturation to C. chincnsis Boh., 

 but at once distinguished by the dark antennae, the infuscate legs, 

 the more obscure coloration of the elytra and the blacker abdomen.

On page 85 (Trans. Ent. Soc. 1918) of the first part of 

 this paper, two species referred to the genns Holisus were 

 described, but further investigation into their structure 

 shows that although possessing a remarkable resemblance 

 to this genus, yet the structure of the mouth-parts and 

 tarsi is so different that it is necessary to form a new genus 

 for their reception, which would appear to form a transition 

 between the Bolitocharini and the Staphyliiiini, the genus 

 Thecfvra probably being the closest relation in the former 

 group.
