"Wisconsin, June; Durham, New Hampshire; Aweme and Winnipeg, Mani- 

 toba, May; Ottawa, Canada. It is found also in New York, New Jersey, 

 Maryland, Massachusetts, Maine, Pennsylvania, Ohio, Indiana, Illinois, 

 Michigan, Nebraska, Kansas, Texas and New Mexico. 



H. H^MATiCA Gorh. Cuernavaea, Morelos, Mexico. This was common 

 with H. gorhami, being even more plentiful than that species. The type 

 locality is Mexico, (Puebla and Cuernavaea). 



H. LECONTEi Wolc. (new name for H. suhcenea Lee, not Spinola). This 

 name is here proposed for the species identified and described as H. suh- 

 cenea by LeConte (Ann. Lye. Nat. Hist., N. Y. V, 1S49, p. 26) which is quite 

 different from the true suicenea of Spinola (Mon. Cler. II, 1844, p. 51). 

 The latter appears to be very rare, if my identification of it is correct, and 

 is known to me from Massachusetts only. Ou the other hand, H. lecontei 

 is common and widespread, as will be shown by the following records. Old 

 Orchard, Maine, June 23 ; Durham, New Hampshire ; Chicopee, Massa- 

 chusetts; Aweme, Manitoba, June; Greeley, Georgetown, Colorado Springs, 

 Ouray and Salida, Colorado, June and July ; Fort Douglas, Utah ; Bodie and 

 Soldiers Home, California; Flagstaff, Arizona, July; Magdalena Mountains 

 and Cloudcroft, New Mexico. It is found also in New Y'ork, New Jersey, 

 Vermont, Ohio, Nebraska, Montana and the Lake Superior region. The ex- 

 isting Illinois record is founded upon an erroneous identification. In the 

 semi-arid regions of the west, this is the most abundant Hydnocera and 

 may be beaten from various shrubs. 



H. TRICOLOR Schaeff. Cameron County, Texas, September. The type 

 locality is Brownsville, in this county. 



H. wiCKHAMi Wolc. Santa Rita Mountains, Arizona, September, 

 (TYPE). 



H. BIMACULATA IVoIc. Amedec, California, July, (TY'PE). 



H. ASPERA Wolc. Cuernavaea, Morelos, Mexico, (TY'PE). 



H. siXGULARis WoJc. n. sp. Elongate, feebly shining, aeneous black, 

 moderately densely clothed with short pale pubescence, antennae and a large 

 subscutellar spot pale yellowish, legs black, knees and anterior and middle 

 tibiae and tarsi testaceous, posterior tibiae and tarsi pieeous brown. Head, 

 including the prominent eyes, as wide as the elytra, rather coarsely ru- 

 gosely punctate, front feebly impressed. Prothorax slightly wider than 

 long, punctuation same as that of the head, lateral fovete neither very 

 large nor strongly impressed, sides broadly and rather feebly dilated at 

 apical two-fifths, nearly straight and feebly convergent posteriorly. Elytra 

 shorter than the abdomen, moderately finely and very densely punctate, 

 post-scutellar region depressed, humeri distinct, sides parallel, apices ob- 

 liquely truncate, dehiscent at the suture, lateral margin posteriorly , and
