ART. 1 LARVAE OF AMERICAN TENEBRIONINAE ST, GEORGE. 9 



sapwood of maple, oak, chestnut, tulip, and sycamore trees. Adults 

 of this species usually emerge about the first week in July. A single 

 larval specimen, collected by D. W. Snyder at Luebo, Congo, Africa, 

 appears to be closely related to this genus. 



The genus Glyptotus LeConte, containing the single species 

 crihratus LeConte, is represented by only one larval specimen. It 

 was taken by H. S. Barber from a dead limb of a palm tree {Thn- 

 nax) on Big Pine Key, Florida, March 6, 1919. This specimen was 

 determined by the writer, by locality, by comparison with size of 

 adult and by a process of elimination of larval characters. Doctor 

 Schwarz states that the species eribratus is about the only one there 

 of its size and that it occurs in large numbers. 



The genus Upis Fabricius is represented by its only species ceram- 

 hoides Linnaeus. The reared material consists of several larvae 

 which were taken by S. A. Rohwer from beneath the bark of a dead 

 white bircli tree at Trout Lake, Wisconsin, September 23, 1913. 

 Some larvae of this lot of material were caged September 27 and 

 from them an adult emerged July 3, 1914. Of the material not 

 associated by rearing experiments there are several larvae which 

 were taken by H. G. Hubbard on the shores of Lake Superior, Michi- 

 gan, July, 1876 ; and one larva taken from a decayed log by the same 

 collector at Hood River, Oregon, May 21^ 1892. 



The genus Tenebrio Linnaeus, of which Leng recognizes the three 

 species ohscurus Fabricius, molitor Linnaeus, and picipes Herbst, is 

 well represented by material from various parts of the United States 

 and a few specimens from Europe. Part of the material from this 

 country has been reared. 



The larval habits of the two first-mentioned species are interesting 

 in view of the fact that they have so many hosts. Besides being found 

 in stored grain, they have also been found in a nest of Bmnhus, debris 

 of a flying squirrel's nest, in Tigridia., in roots of Althaea, and in 

 hydrolyzed sawdust, which was being fed to cattle. 



The material rej^resenting picipes Herbst consists of the following: 

 Larva and adult taken from a rotten log at Rockville, Pennsylvania, 

 November 13, 1913 (H. B. Kirk, collector) ; three larvae and two 

 adults found in nest of Bomhus at Detroit, Michigan, probably in 

 July, 1876 (PI. G. Hubbard, collector) ; and a single larval specimen 

 collected "on strawberries" at De Queen, Arkansas, March 26, 1921 

 (J. W. Berg, collector), 



DISCUSSION OF LECONTE'S OLD GENUS NEATUS. 



It may have been realized from the comments in the preceding dis- 

 cussion that, in the little group of species which are included under 

 the genus Tenehi^o Linnaeus, the species picipes Herbst occupies a 

 position distinctly separate from the more typical forms, molitor
