In catifornicus ( J\ the pubescence is moderately long over the whole 

 metasternum. In the 9 it is sparser and shorter and usually there is a 

 triangular median space naked. 



P. imbricornis Q is entirely naked beneath. 



P. fissicornis $ as in imbricornis, 9 entirely naked but with the 

 metasternum more thickly punctulate than in imbricornis. 



P. palparis J 1 with a shorter pubescence than has imbricornis, Q as 

 in imbricornis. 



Homcesthesis integer rf has the pubescence very short The 9 i & 

 naked and quite smooth. 



H. emarginaius $, has the pubescence much longer. The 9 is as 

 in integer. 



In Tragosoma Harris ii both sexes are similarly hairy. 



Mecas inornata Say. Among three specimens given me many 

 years ago as Stenostola saturnina, from Texas, one was found to have the 

 claws much more deeply cleft and with the inner divisions broad, lobe- 

 like and rounded and approximate at tip instead of being moderately cleft 

 with the inner divisions acute. While it is perhaps possible that an ex- 

 tensive series may show this to be but an extreme variation, it is proposed 

 that Say's name be used for this form and Leconte's name saturnina for 

 the other until evidence occurs to show that they should be reunited. In 

 examining the Leconte types recently with Dr. Horn it was found that 

 the type of saturnina was of the form referred to above under that name. 

 TJie Leconte specimens of inornata averaged a somewhat larger size and 

 where rather more ochreous in color. The pair of small denuded spots 

 on the thorax were present and absent in specimens of both forms. Both 

 sexes occurred of each. In comparing my own single specimen of 

 inornata, which is a 9, with saturnina, the elytra appeared to be some- 

 what less punctured and with the punctures becoming obsolete at tip, 

 while in saturnina the punctures, although finer, are distinct at tip. In 

 my specimens the size would afford no criterion, they being all about the 

 same. M. inornata is from Dak., Kans. , Tex. M. saturnina is from 

 Kans. , Tex. 



Magdalis armicollis Say. This and pallida Say are retained as 

 distinct in the Henshaw List. The latter name belongs to the ^ and the 

 former to the $ and both should be known as armicollis. The <$$ are 

 usually darker, either entirely brown, or with the head and thorax dark and 

 the elytra pale, while the 9 9 appear to be always pale above. The eyes of 

 the $ are a little larger and more approximate above ; the antenna' are a 

 little longer, the scape passing back of the front margin of the eyes but in 

 the 9 only barely reaching them ; the abdomen is somewhat flattened in
