12 JOUENAL OF ENTOMOLOGY AND ZOOLOGY 



Study by some one having the necessary material. As pointed out 

 by Mr. Charles Dury in his Cincinnati List, pulcher is without doubt 

 merely a variety of lahiatiis. Mr. Dury also suggests that fulvipes 

 may be only a yellow legged form of higiihris, but this, I think, can- 

 not be possible, as the two have distinctly different male genitalia. 

 Mr. Dury's specimens with pale legs may really be luguhris, but the 

 true fulvipes should rather be united with newmani, as suggested by 

 Blatchley. There is a distinct possibility that the material now 

 passing as collaris may involve more than one species; a problem 

 for the future. 



As compared with the West Coast species, those of the Eastern 

 United States are not only less numerous, but exhibit far less struc- 

 tural variation. For example: In all the species of the Atlantic 

 region the tarsal claws are similarly broadly, strongly toothed; 

 while in those of the West Coast there are three distinct forms of 

 ungual tooth. In the Eastern species the antennae are quite uni- 

 formly feebly serrate; in the Pacific species the antennae vary all the 

 way from feebly serrate through strongly serrate to pectinate and 

 flabellate. In the Eastern species the head is always very finely 

 and sparsely punctate; in the Western ones It varies from very finely 

 to quite coarsely and densely punctate. In the Eastern species vari- 

 ations In color are seemingly confined to the legs and prothorax; 

 while in those of the West Coast there Is a most pronounced tend- 

 ency to dichromatism In the color of the elytra In many species, with 

 a lesser amount of variation in the color of legs and prothorax. In 

 all the Eastern species there is a sexual modification of the elytral 

 apex In the male; in the Pacific species this sort of modification exists 

 In greater variety, but is by no means universal, there being a con- 

 siderable number of species In which It is totally lacking. 



I regret that I am unable to say anything concerning the larval 

 habits of the species of Pedilus. The beetles themselves are found 

 — sometimes In numbers — on flowers, appearing rather early in 

 Spring — March and April — in the vicinity of the Coast, but consid- 

 erably later In the season in the Sierras.
