242 ENTOMOLOGICAL NEWS. f June, 'l6 



During a recent visit of William C. Wood, Esq., of New 

 York City to Guantanamo, we went over the series of more 

 than fifty specimens of rimosa rimosa, and congratulans in my 

 collection and, after deliberate and careful study, came to the 

 conclusion that congratulans did not have specific standing, 

 for the following reasons. 



In the above mentioned series were intergrades from rimosa 

 rimosa to congratulans, not one, but several of them. The 

 specimens of this series were all taken at light in Guantanamo, 

 the dates ranging over a number of years. 



However, it was Gundlach who first noticed that there was 

 no specific difference between them, and he mentions the fact 

 in his work, "Contribucion a la Entomologia Cubana," Ha- 

 bana, 1881, where, on pp. 215-218 he discusses Dilophonota 

 rimosa. I herewith translate the part referring to congratu- 

 lans, as follows: "In 1858 I found, at Santiago de Cuba, an 

 individual which I considered a different species, and named 

 it congratulans. I made this known to Mr. Grote, who also 

 considered it a new species, describing it as such in the Annals 

 of the Lyceum of Natural History, New York, Vol. viii, 

 November, 1865. The type was not returned to me. Through 

 Mr. Grote's carelessness this specimen, together with specimens 

 of other new species belonging to me, went with the collec- 

 tion of the unfortunate Mr. Robinson, when it was given to 

 the Central Park Museum of New York. This I learned from 

 a letter of Mr. Grote. 



In 1878, I reared a batch of caterpillars of this species and 

 found among the moths some dark colored individuals that I 

 must consider the same as my congratulans, and for this rea- 

 son, I consider this name applicable only as a dark form of 



rimosa." 



Gundlach then goes on to describe congratulans as follows: 

 "It differs in having the forewings so dark that one cannot see 

 the ashy ground color of the type [by "type" he means rimosa}, 

 in another example of my collection the lighter ground color 

 of the type is slightly evident." 



There can be no doubt from the above as to the status of
