Classification of iJie Colcoplerous family Endoynyrlndac. 25 



pointed behind as in D. hornecnsis. The insect is nnich 

 broader and more liemispherical. and the elytra have rather 

 wide flattened margins. The chib of the antenna is much 

 smaller, its first and last joints being much narrower than 

 the middle one, the first triangular and the other two very 

 short and closelv articulated. 



Dryadites purpureas, sp. n. 



Nigor, olytris purpureis, pronoti lateribus elytrorumque macula 

 subrotunda post medium posita sauguineis ; ovalis, convexus, nitidus, 

 pronoto parum lato, lateribus haud regulariter arcuatis, marginibus 

 baud excavatis, angulis anticis vix productis aut acutis; elytris 

 sat latis, lateribus modice explanatis; auteuuis haud longia, cfava 

 oblonga, sat angusta, articulis connatis. 



Long. 5 inm. ; lat. max. 3'5 mm. 



Hah. W. Sarawak, Borneo : Quop (6'. E. Bryant, 

 March). 



Only a single specimen w^as found. 



The elytra are of a deep purple colour, and each has a 

 deep l)lood-red patch behind the middle. The prouotum is 

 relatively narrower than in D. horneensis and D. lafipcnnis, 

 its sides are not hollowed as in those species nor its lateral 

 margins evenly rounded, and the front angles are blunter. 

 The antennae are rather shorter, the club narrow, closely 

 articulated and parallel-sided and the third joint relatively 

 less elongate. 



Genus Mycetina. 



Mycelina candens Gorh., is obviously synonymous with 

 M. castanea Gerst. Although he has omitted to mention 

 the fact, Gorham's type is a male, of which sex Gerstaecker 

 carefully detailed the well-marked characteristics, makiiig 

 the former's error more surprising. 



There appears to be a tendency in this genus, contrary 

 to that generally observed in beetles, for the male to be 

 of shghtly larger size than the female. 



It is difficult to understand why Lycoperdina testacea 

 Ziegl., was placed by Leconte and Gerstaecker in tliis 

 genus, from which it differs widely, as its very loosely- 

 jointed antennal club indicates. The absence of a stridu- 

 latory flange to the prouotum excludes it from the present 

 group, and I refer it to the geiius Danae.
