56 NATURAL HISTORY BULLETIN 



E. QUADRiGUTTATUS OUv. lowa City, loAva, April 5; Hampton, New 

 Hampshire, May 18; Malcolm, Nebraska, June 4. It is recorded from On- 

 tario, Maine, Vermont, Rhode Island, :\[assaehusetts, New York, New Jersey, 

 Pennsylvania, Ohio, Indiana, Illinois, Wisconsin, Michigan, Minnesota, Kan- 

 sas, Missouri, Georgia, New Mexico, Arizona, California and Mexico. 



E. QUADRIGUTTATUS var. RUFivENTRis Spin. Mt. Katahdin, Maine, 5000 

 feet, June 29; Toronto. Canada, same date. It is known from Vermont, 

 New York, Wisconsin, Michigan, Kansas, California and Mexico. 



E. ROSMARUS Sen/. Iowa City, Iowa, June 29; Atoka, Indian Territory, 

 June 14; Little Rock, Arkansas, May. Inhabits also Louisiana, Florida, 

 Georgia, Virginia, District of Columbia, Maryland, New York, New Jersey, 

 Massachusetts, Pennsylvania, Ohio, Kentucky, Indiana, Illinois, Nebraska, 

 Missouri and Kansas. In my experience, this occurs on flowers. 



E. BOMBYCiNUS Chcv. Cueruavaca in 2iIorelos and Tepehuanes in Du- 

 rango, Mexico, July and August. This is a flower loving species like the 

 last, and was taken in some abundance in sweepings on heavily overgrown 

 hillsides. 



E. EXiMius Mann. Nanaiino, Vancouver Island, May 8; Salem, Oregon; 

 Pasadena and Soldiers Home, Los Angeles County, California. 



E. MUTTKOWSKII Wolc. Bayfield, Wisconsin, where two specimens were 

 found running on a fence made chiefly of poplar logs. The type of this 

 species was labelled merely "Wis." Dr. Muttkowski took a specimen at 

 Prescott, Pierce County, Wisconsin, between July 13 and 19, 1910. The 

 color of the abdomen of this fresh specimen is red, (not yellow, as in the 

 evidently faded type) and the apical ventral segment is piceous. In my 

 examples, the abdomen is red throughout. 



E. SPINOL.^ Lee. Alpine and Marfa, Texas, June and July; Shady Run 

 in the. Pinal Mountains, Arizona, July; Wallace County, Kansas, July; 

 Tepehuanes, Durango, Mexico. This showy beetle sometimes occurs in 

 large numbers in the flowers of various yuccas and related plants in the 

 warm desert regions of the southwest. It is known to occur in New Mexico 

 and California, as well as in the states noted above, and a doubtful record 

 is extant for Kentucky. 



E. MCESTUS Klug. Colorado Springs, Salida and Ouray, Colorado, July; 

 Coolidge, New Mexico; Flagstaff and Bright Angel Camp, Arizona, June 

 and July. Sometimes abundant running in the sunshine on cut trunks of 

 conifers or hiding in the dying foliage. I have never seen it on flowers 

 and the habits are suggestive of Thanasimus rather than of Enoclerus. It 

 has a wide range and is kno^\"n from several states other than those named 

 above, namely South Dakota, Wyoming, Nebraska, Montana, Washington, 

 Oregon and California, extending south into Mexico.
