Of seventeen species quoted by Grote as identical with Euro- 

 pean species, Dr. Speyer has not yet seen specimens. 



Of course the detailed exposition for each species can not be 

 given in a short report. 



[Much to our regret, since we desire to have no anonymous articles in Psyche, the au- 

 thor of the above report declined to allow his name to be appended to it. Ed.] 



Varieties of Cleora pulchraria Minot. 



This beautiful species stands entirely alone in our fauna, as 

 it is our only representative of a remarkable European genus, 

 of which the most prominent structural characters are the 

 strongly pectinate antennas of the male and the extruded ovi- 

 positor of the female. In this part of Massachusetts the insect 

 appears to be quite rare, and local in its distribution ; this is 

 probably due to the fact that the larvae feed on pine ; but I 

 have been able to obtain, in September and October, resting on 

 the trunks of a grove of these trees, behind the Museum of 

 Comparative Zoology at Cambridge, nearly two hundred speci- 

 mens of the moths. One must naturally expect, in the colloc- 

 ation of so many specimens, to see a certain number of aberrant 

 forms, but I was by no means prepared to find the extraordi- 

 nary amount of variation actually exhibited. I give a short 

 description of the general plan of the simple ornamentation of 

 the species, in order that the variations from it may be more 

 readily appreciated. The anterior wings are crossed by two 

 distinct black lines, the interior lobate, the exterior sharply 

 dentate between the nervules ; between them the discal dot is 

 always seen, very black and conspicuous; the posterior wings 

 have the discal dot, and following it a single median dentate 

 line. The features most liable to vary are as follows, the most 

 inconstant being placed first : the ground color, the structure 

 and proximity of the median lines, the color of the vertex and 

 front, and the shape of the wings. Before mentioning each 

 individual variety, I would remark that no class of variations is 

 confined to either sex ; both sexes appear to vary within the 

 same limits and to the same extent. 



The ground color, which shows the greatest diversity, in the 

 normal form is white, more or less thickly sprinkled with black
