cha is attenuata Csy., Bull. Cal. Acad. Sc. I. 1885, 306, and 

 has the following synonymy: lineata Csy., Ann. N. Y. Ac. 

 Sc. VII. 1893, 376; fenyesi Brnhr., Deutsch. Ent. Ztschr. 

 1906, 337; longipennis Csy., Mem. Col. II. 1911, 219. This 

 species must be removed from Gyronycha on account of the 

 5-5-5-jointed tarsi, and must be made, for the time being, 

 the representative of a new genus: Gyronychina Csy. (Mem. 

 Col. II. 1911, 218). It seems to belong in the neighborhood 

 of Apimela M. & Rey, and also of Aleuonota Thorns., in 

 case this latter genus proves to possess 5-5-5-jointed tarsi. 



Mr. .P. de Peyerimhoff informs me, in a letter dated the 

 24th of June, 1911, that in both Apimela and Aleuonota the 

 front and middle tarsi are pentamerous. I found this to be 

 the case in Apimela, but not in Aleuonota, although I may 

 be mistaken. According to Peyerimhoff, both genera ought 

 to be placed near Phloeopora Er. 



I have in my collection a large series of Gyronychina at- 

 tenuata Csy., all from California, the specimens showing a 

 great range of variation. Some are very pale, reddish brown 

 and shining, while the darker specimens are more opaque, 

 especially on the elytra ; the antennae are longer or shorter, 

 according to the size of the specimens and also to the method 

 of their preservation ; the head, prothorax, elytra and abdo- 

 men also vary to a considerable extent, and any attempt to 

 base a species on such minor differences would result in 

 splitting my series into at least a dozen species. 



The males are probably the more opaque specimens, while 

 the females seem to be the pale and shining ones; the prob- 

 able males are much more frequently taken than the females. 



The life habits of Gyronychina attenuata iCsy. are the 

 same as those of Gyronycha valens Csy. I took most of 

 my specimens in evening flight, and some of them in the 

 storm debris of the Arroyo Seco. 



DR. WALTER HORN, of Berlin, expects to be in Italy until mid-March 

 for the benefit of his health, as he has been suffering from bronchial 

 pneumonia.
