OF WASHINGTON. VOLUME XIII, 1911. 13 



Mr. Schwarz remarked that tropical appearance does not al- 

 ways depend on moisture, for in eastern Guatemala there is a 

 large reg-iou with the appearance of the Potomac River region, 

 but where it rains every day. 



-Under the heading "Short Notes and Exhibition of Speci- 

 mens" Dr. Dyar showed a copy of the first part of Lord Wal- 

 singham's portion of the Biologia Centrali-Americana, which is 

 to comprise the Tineina. He said: 



The part shown has 24 pages with one plate, embracing 

 the Lavernidse and part of the Gelechiidae. Though but a 

 small part of the work, it exhibits the general style and make- 

 up to be expected of the whole. The general plan of treat- 

 ment employed in the previous parts on the Lepidoptera 

 Heterocera is continued, perhaps unavoidably. This excludes 

 all tables of families, genera, and species, as well as all diag- 

 noses of old species, leaving the descriptive matter confined to 

 the characterization of new genera and species. The treat- 

 ment is accidentally much more largely monographic than in 

 previous sections of the Lepidoptera Heterocera, owing to the 

 circumstance that a large majority of the forms treated are here 

 first described. Each new genus is accompanied by a text- 

 figure of venation and head structure, a most useful and com- 

 mendable innovation. We wish these had been given for the 

 type species of the old genera as well. Such figures would have 

 largely replaced the missing synoptic tables. There are in 

 the part 36 species treated in 20 genera. Of these over 80 

 per cent of the species and 30 per cent of the genera are 

 "new." The colored figures on the plate are given much en- 

 larged. The names of the authors and works quoted in the 

 bibliography are too greatly abbreviated. The less familiar 

 ones are quite unintelligible. The work on the whole is ad- 

 mirable, and in several important respects is an improvement 

 on the previous volumes of the Lepidoptera. We desire to 

 congratulate the eminent author on the appearance of the 

 first part of this monumental work, which has been so long 

 expected. 



Dr. Dyar read a communication 1 from Mr. R. Shelford, 

 of the University Museum, Oxford, England, which was a 

 reply to Mr. A. N. Caudell for certain criticisms of Mr. Shel- 

 ford's work. Mr. Shelford objected to Mr. Caudell's quota-
