NOTES ON NOMARETUS, WITH DESCRIPTIONS OF TWO 

 NEW SPECIES. 



BY E. A. SCHWARZ. 



The discovery of two undescribed species of Nomaretus, one of 

 which differs remarkably from the nearest allied species in the 

 tarsal characters of the male, led to a desire of examining and 

 comparing the males of all our species. In this I was unsuc 

 cessful, owing to the scarcity of specimens in our collections, and 

 the idea of contrasting the species according to the tarsal structure 

 of the males had to be abandoned for the present. However, in 

 the course of examination of the available material a number of 

 other distinctive characters, irrespective of sex, were found, and 

 the following synoptic table, which has been drawn up conjointly 

 by Mr. H. G. Hubbard and myself, may be of some use in con 

 nection with that given by Dr. Horn (Bull. Brooklyn Ent. Soc., 

 i, 1879, p. So).
