 of it might apply to this and other species.

 A long series of this species proves it to be widely distributed 

 and apparently common. Like the 3 following species its belongs 

 to a section of the genus in which the mesosternal stria exists 

 at the sides only. 



Taken in Birmania at Bhamò and Shwegoo-Myo and in Tenas- 

 serim at Thagatà.

This species is almost similar to annellus but the sulcus in 

 the pygidium is elliptical and transverse instead of being circular. 

 Marseul has found difficulties in differentiating the Paromali 

 and as an instance P. acistrigus, Annali del Museo Civico di 

 Genova XIV, 1879, p. 276, may be quoted. Entomologists have 

 found it difficult to pair the sexes of the Lucanidae in the ab- 

 sence of a long ' series of specimens labelled at the time of 

 capture by the captor. Similar registration is necessary with 

 the Paromali, but as they are an obscure portion of the Co- 

 leoptera , collectors abroad cannot always be expected to provide 

 authors with the data necessary to elucidate the group. For 

 these reasons, being both collector and describer I have left the 

 Japanese Paromali, about 14 species, untouched, for over 6 

 years from a feeling I could not unite the sexes with certainty.
