CELYPHUS DIFFICILIS Malloch 



Celyphus ddfficilis Malloch, Ent. Mitt., vol. 16, p. 161, 1927. 



This species was described in the paper of mine already referred 

 to herein, and is known only from Formosa. 



CELYPHUS AURORA Karsch 



Celyphus aurora Karsoh, Berlin, Ent. Zeitschr., vol. 28, p. 173. 1883. 



This species is brownish testaceous, with a conspicuous metallic 

 blue sheen on face and frons, all of dorsum of thorax and scutellum, 

 most pronounced on latter. The most noticeable character for dis- 

 tinguishing the species is the deep black mark on each side of face 

 between antenna and eye. The arista is as broad on basal portion 

 as width of third antennal segment and the apical hairlike portion is 

 as long as it and quite long haired. The frons in the specimen be- 

 fore me is not depressed, but almost even and rounded on vertical 

 margin, and the four vertical bristles are well developed. The 

 abdomen and fore femora are testaceous. The scutellum is wrinkled 

 on basal half only. 



Length, 5.5 mm. 



Locality, Langkat, Sumatra (Deut. Ent. Inst.). 



CELYPHUS OBTECTUS Dalmann 



Celyphus ohtectus Dalmann, Anal. Ent., p. 32, 1823. 



This species is very similar to the preceding one, but the head and 

 thorax are more pronouncedly yellow testaceous and less tinged with 

 blue, the scutellum is deeper blue and there are no dark spots on face. 

 The frons is slightly depressed at vertex and the arista is different 

 m structure, as stated in the key. 



Length, 4.5 mm.
