This species was originally described from St. Vincent, but 

 Mr. Smith did not rediscover it in this island. Mr. Cockerell 

 has sent it to the British Museum from Jamaica ; Mr. Bollman 

 has recorded it from Cuba, and Meinert from St. Croix. 



By some authors, e.ff. Meinert and Bollman, this species is 

 regarded as synonymous with the Oriental form M. punctifrons, 

 whichi it resembles in having forty-nine pairs of legs. All the 

 Neotropical examples, however, that I have seen are smaller and 

 paler coloured than M. punctifrons, and seem to have the head 

 considerably narrower.
