short common, apical elytral black spot. In addition to these 

 there is a small lateral, prehumeral spot on the thorax, usually 

 encroaching a little onto the base of the elytra and sometimes 

 connected with the discal spot ; in front of it are two small lateral 

 spots of which the lower is very small but present in all speci- 

 mens. The metasternum is clothed with white scales as in 

 cattleyae and the abdominal sternites are similarly clothed, ex- 

 cept that the patches on the second segment fuse into a con- 

 tinuous transverse band. 



The eleven specimens (5 cf d 71 , 6 99) before the writer (and 

 six specimens of cattleyae} were all taken by Mr. Weiss in an 

 orchid house at Secaucus,N. J,. during the past summer, and have 

 generously been loaned (except of course the type in the British 

 Museum) from the following collections: 



Mr. H. B. Weiss, 7 specimens labelled "Bergen Co., N. J.," 

 two of which are retained for the National Collection, by the 

 kind permission of the owner. 



Mr. E. L. Dickerson, 2 examples labelled "Secaucus, N. J., 

 VIII." 



Mr. A. C. Frost, 1 example. 



American Museum of Natural History, 1 example. 



The notices of these orchid Choli known to me are as follows: 



1877 Pascoe (Proc. Ent. Soc., Lond., 1876, p. XXX, named and gave short 

 diagnosis of Cholm forbcsii from a specimen found among some 

 supposedly Ecuadorian orchids at Highgate, England. 



1903 Champion (Biol. Centr.-Amer. Coleop., vol. IV, pt. 4, p. 306, pi. 

 XVI, figures 12 and 13) describes and figures two new species, C. 

 nigronotatus from Nicaragua and Panama (two specimens), and 

 C. nigromaculatus from Panama (a pair) the first of which he 

 compares with Pascoe 's species. 



1906 Champion (I.e., p. 724- footnote) corrects an error in above. 



1916 Champion (Ent. Mo. Mag. (3), vol. 2, Sept., p. 201) describes a new 

 species. C. cattleyae from a specimen found by Mr. Weiss breed- 

 ing in bulbs of Cattleya gigas in a New Jersey greenhouse. A 

 photo of the same species from Milwaukee, Wis., is cited and the 

 three preceding species are mentioned. 



1916 Barber (Proc. Ent. Soc. Wash., vol. 18, p. 177, pi. 13) figures and 

 describes the Milwaukee specimen as C. cattleyarum. 



1916 Fracker (Wisconsin Horticulture, vol. 7, Oct., 'p. 27) records the 



occurrence of Cholus caltlei/ac (without using a name) in orchid 

 houses in Milwaukee. 



1917 Weiss (Ent. News, vol. 28, p. 28, pi. V, fig. 2) describes Hie injury in 



greenhouse's by C. cattleyae and C. forbexii and figures the specimen 

 of the former species now preserved in the American Museum of 

 Natural History.
