teenth and twenty-eighth of April, 1903. Of Mr. Watson's lot two aberrant males 

 hatched on the fourth and nineteenth of August, 1903. Of 35 cocoons collected 

 from the same locality late in 1903 all produced typical forms the following season. 

 During the fall of 1904 he again obtained 30 cocoons from Crotona Park from which 

 lot he obtained one aberrant female on May 9, 1905. 



To supplement Mr. Watson's exhibit Mr. Joutel showed typical cynthia and also 

 a variation with the body nearly white, the wings with a broad, transverse white band 

 that lacked the inner border, and base of wings nearly white. He also showed ex- 

 amples of a closely allied species from Japan that is nearly like cynthia but has the 

 transverse lines differently angulated and shows by the different structure of the cocoon, 

 pupa and imago that they are distinct. This is known as pryeri. Specimens from 

 India also shown differed from both of the above in makings and cocoons and were 

 described as insiilaris. Another form shown was from central Mongolia having the 

 outer transverse space a dark reddish brown, the wings not produced at apex but 

 short and rounded, and the body nearly white. The cocoons are strikingly different 

 from the others in shape, color and structure, being pure white in the female and 

 bright rust-red in the male, and lacking the stem. The name of this species is unde- 

 termined. Mr. Joutel made some remarks on silk culture in connection with the 

 cocoons of the above and other species and explained the difference between the open 

 and closed cocoons and their respective value for silk. He spoke of his experiments 

 of the last seven or eight years with some of the hardy silk worms of Asia and of their 

 value as silk producers for commercial purposes in this country. 



Mr. Leng exhibited a few Nitidulidse and read the following notes in regard to 

 their habits. The Nitidulidse are commonly known as "sap beetles" and include 

 those beetles which are always to be found in spring on stumps of freshly cut trees 

 from which the sap is oozing. The family also includes a number of species and 

 genera which are found about decomposing substances of various kinds They may 

 be><;lassified according to their usual occurrence as follows : 



On sappy tree stumps and logs, the following genera are found : Carpophilus, 

 Colastus, Ips, Amphicrossus, Cryptarcha, Prometopia, Soronia (except ulkei) and 

 Epuma peltoides. These genera are also found by sifting old leaves about tree 

 stumps having perhaps been attracted to the locality by sap at some previous time. 



On flowers the following occur : on nettles, Brachypterus urticce and Aleligethes ; 

 on Elder, Cercus abdominalis ; on Yucca, Carpophilus yuccce ; on agave, Anthonczus 

 agavensis ; on Convolvulus (Bind weed), Conotettis [C. mexicanus, on greenhouse 

 species) ; on Brassica, Meligethes. 



On decaying animal matter especially greasy bones : Nitidula and Oviosita. 



On foreign dried fruits : Carpophilus hemipterus. 



Under bark on mould : Rhizophagus and Prometopia. 



On fungus : Cychramus, Epuraa, Phenolia, Pallodes, Pocadius (on Lycoperdon), 

 Oxycnemus (on phallus or stink-horn only), Cybocephalus (in clusters on fungus- 

 grown logs and on twigs), Epurcea monagamia (on small white globular fungus of 

 pine). 



On rotting fruit : Stelidota geminata. 



In ants' nests under stones, Saronia ulkei (the ant being Cremastogaster lineo- 

 lata Say, var. lutescens Emery). 



On palmetto : Smicrips palmicola.
