8 PBOCEEDINGS OF THE NATIONAL MUSEUM. vol. 65. 



R. C. Shannon from an oak log at Dead Run, Fairfax County, Vir- 

 ginia, August 6, 1915; and a larva collected by C. G. Marshall at 

 Silver Hill, Maryland, February 22, 1916. 



An undetermined larva, closely related to the genus HaplandruSy 

 was taken by H. S. Barber at Brownsville, Texas, who suggests that 

 it may represent a species belonging to the Mexican fauna. 



The genus CoelocneTnis Mannerheim, of which there are five 

 species, is represented by dilaticoUis Mannerheim. The material con- 

 sists of two larval specimens, not associated by rearing, collected 

 by D. W. Coquillett in Los Angeles County, California. The rest 

 of the material is without specific determination and consists of two 

 larvae taken by H. S. Barber from under stones at Williams, Arizona, 

 between May 30 and June 8, 1901 ; one larva taken by E. A. Schwartz 

 from the ground at Oracle, Arizona, July, 1898; and a third larval 

 specimen taken by Schwarz and Barber from Cacao trees at Aguas 

 Alta, Verapaz, Guatemala, April, 1906. 



The genus Iphthimus Truqui, consisting of three species and three 

 varieties, is represented by serratus (Mannerheim) and its varieties. 

 The material representing the variety sublaevis Bland consists of: 

 Larval specimens found in Piniis fonderosa at El Paso County, 

 Colorado, February 26, 1914 (A. B. Champlain, collector), from a 

 larva taken with them an adult was reared July 3, 1914; two larval 

 specimens, not associated by rearing, taken by E. A. Schwarz 

 and H. S. Barber at Williams, Arizona, during June, 1901; and a 

 third larva taken from the decayed part of a telephone pole above the 

 ground, on the Montgomery to New Orleans line, during August, 

 1921. The remaining specimens of the species serratus^ not associated 

 by rearing, were collected as follows: One larva from a decayed 

 log in a Tamarack swamp at Detroit, Michigan (H. G. Hubbard, 

 collector) ; a second larva taken at Field Brooks, California, May 19, 

 1903 (H. S. Barber, collector) ; and a third larval specimen from a 

 sycamore log at Smith Point, Texas, November 15, 1918 (H. S. 

 Barber, collector) . One other larva, determined as Iphthimus species, 

 was taken by H. G. Hubbard from a decayed log at Hood River, 

 Oregon, May 21, 1892. 



The material representing the variety Uwisi Horn consists of four 

 larvae taken together with adults, from under the bark of a tree 

 at Lake Tahoe, California, July 8, 1891 (H. G. Hubbard, collector), 

 and three pupae and one adult taken by F. G. Schaupp at Kelly, 

 New Mexico, July, 1890. 



The genus Alohates Motschulsky, of which there are three species, 

 is represented by pennsylvanica (De Geer). As this species is very 

 common in the eastern part of the United States there are many speci- 

 mens of it. Tlie larval material, of which part is associated by rear- 

 ing, has been taken mainly from beneath the bark and in the outer
