confluent and the intervals (both between series and series and 

 between puncture and puncture of the series) squaraose-rugulose 

 in such fashion as greatly to obscure the puncturation.

C. evanescens, sp. nov. Minus nitidus ; sat brevis ; niger, palpis 



anternarum stipite et nonnullorum exemplorum tarsis 



dilutioribus ; pilis pallidis decumbentibus vestitus ; capite 



crebrius sat grosse punctulato, clypeo sat elongato antice 



minus lato subrotundato vix reflexo ; antennis 9-articulatis, 



clava sat elongata quam articuli ceteri conjuncti vix bre- 



viori ; prothorace leviter transverso, antice leviter angustato, 



crebrius rugulose sat grosse punctulato, lateribus arcuatis- 



(latitudine majori vix pone medium posita), angulis anticis 



acutis posticis obtusis (sed bene determinatis), basi media 



minus fortiter lobata ; scutello coriaceo parum insequali ; 



elytris crebre minus fortiter seriatim punctulatis, parum 



rugulosis, interstitiis minus distinctis ; tibiis anticis fere ut 



C. punctulati sed brevioribus latioribus ; tarsis ut 



C. discedentis. Long., IJ 1.; lat., 4 1. 



This miuute Lamellicorn is evidently allied to C. discedens but 



may be at once separated from it and from all the other described 



Caulobii by its clypeus evidently more elongate and very much 



less strongly reflexed at the apex. Although I have not broken 



off an antenna for examination under a microscope (the only way 



to be absolutely certain of the number of minute joints in the 



funiculus) I have, I think, seen quite plainly through a Codding- 



ton lens that there are four joints in the funicle, — so that the 



antennae are nine- join ted.

MiECHIDIUS. 



This genus presents the difficulty usual in Australian ento- 

 mology of containing a certain number of species so vaguely 

 described that it is impossible to identify them without examin- 

 ing the types. The number of names that have been given to 

 species of McecMdius is, I believe, 33 (excluding ^/6er<is?, Fairm., 

 hilobiceps, Fairm., and gracilis, Waterh., which have not the pro- 

 sternal sutures open to receive the antennae and have the Sericid 

 structure of the mouth ; they are allied to Diphucephala and are 

 members of, or very near to, the genus Upholds). Of the 33 

 names really appertaining to M(Bchidius four must be dropped as 

 synonyms, viz. Kirhyanus, Westw. = spuriiis, Kirby, excisus, 

 Waterh. = riigosicollis, Macl., raddonanus, Westw. = sordidus, 

 Boisd., and sinuaticeps, Blackb. = mellyanus, Westw. Of the 

 remaining 29, two (viz. obscurus, Macl., and pa7'vulus, Macl.) are 

 so slightly described that it is impossible to form a clear idea of
