eum which are very fully discussed by Dr. Skinner in the paper 

 mentioned above, refers to the brown suffused form of 

 svrichtns. Unfortunately Reakirt's original description does 

 not mention any of the absolute distinguishing characters of 

 syrichius, but neither does it mention their absence, so we see 

 no reason whatever to doubt the validity of the types, a con- 

 tingency which Dr. Skinner suggests. We have examined th* 

 t\pes, and there is a compared male in the Barnes collect ion. 

 The brown suffusion on the under surface of the secondaries 

 is very conspicuous, and offers, in our opinion, ample basis 

 for the separation of montivagus as a form of syricJitiis. This 

 is the form described by Dr. Reverdin as fnmosa. The speci- 

 men which he figures is one of the most heavily suffused, but 

 this character is subject to considerable variation. A recent 

 note from Dr. Reverdin advises us that he was not acquainted 

 with the true identity of montivagus at the time he described 

 fnmosa, due, no doubt, to the misuse of the name for tcssellata 

 for so many years even in our own country. Unfortunately 

 Dr. Reverdin's name must be regarded as a synonym. 



The species described as syrichtides by Dr. Reverdin does 

 not come within our province, and so we have indulged in no 

 speculation on its possible identity with orcits Cr. It is un- 

 doubtedly distinct from our species, as shown by the excellent 

 figures of the male genitalia published by our esteemed 

 colleague. 



The arrangement of syrichtns in the "Check List" should be 

 modified thus :

A note by Mr. Roswcll C. Williams (Ent. News, XXX, p. 

 38) regarding the apparent specific distinctness of //. occiden- 

 talis Skin, and tcssellata Scud, on the basis of genital structure 

 led us to examine a long series of these races recently. The 

 genitalia do undoubtedly show two very easily ' parable forms 

 of valves, but these are connected by a great variety of inter- 

 mediate forms. In true tessellata the valve is provided with a
