Classification of the Oolcoplerous family Endomychidae. 73 



Hab. Borneo : Pcngaron {W. Doherty). 



The type specimen is unique. 



This species is closely similar to M. aqncicornis and 

 hiflagiatus, but in addition to the slight diflerence in 

 coloration it is rather more shining than the former, the 

 punctures upon the elytra being a little finer and less close, 

 the elytra are a little less broad at the shoulders, with the 

 calli less prominent, and the prothorax is a little shorter, 

 less deeply emarginate for the reception of the head, with 

 the front angles less produced and farther apart. The 

 antennae are slender, all the joints being distinctly elongate, 

 the last three of equal length. 



Milichius biplagiatus, sp. n. 



Fcrrugineus, nitidus, supra subtiliter metallicus, singulo cly tro plaga 

 obliqua parum distincta violacea ante medium ornato ; subglobosus, 

 capite crebre punctato, antennis vix elytrorum longitudine aequali- 

 bus, ferrugineis, articulis paulo elongatis, 3° quam 4° paulo longiori, 

 9°-ll° majoribus, subaoqualibus, pronoto irregulaiiter minute 

 punctato, marginibus lateralibus sat late reflexis, postiee fere rectis, 

 angulis acutis; elytris sat fortiter punctatis, callis humeralibus 

 prominentibus, minute punctatis, marginibusque distincte reflexis. 



Long 4-5 mm. 



Hah. Borneo : Pengaron {W . Doherty). 



This also is described from a single specimen. It appears 

 to resemble rather closely M. expetittis Gorh., from Sumatra, 

 although differing in its feebly metallic rusty-red colour, 

 paler at the front angles of the thorax and upon the 

 humeral calli and with an ill-defined oblique blue patch 

 behind each shoulder, as well as by its uniformly reddish 

 antennae, composed of slightly elongate joints, tlie last 

 three forming a narrow club and the terminal one only a 

 little longer than either of the two preceding. The reflexed 

 margins of the elytra arc rather more prominent than in 

 M. apicicornis, but less so than in M. ornatus Arrow, 

 described elsewhere.
