270 REPORT OF STATE GEOLOGIST. 



Measurements: Length of body, male, 27 mm., female, 4-4 mm.; of 

 antenna?, male, 12 mm., female, 14 mm.; of pronotum, male, 7 mm., 

 female, 10 mm.; of tegmina, male, 27 mm., female, 38 mm.; of hind 

 femora, male, 16 mm., female, 22 mm. 



This species has been taken in Indiana only near Pine, Lake Coun- 

 ty, where my assistant, Mr. L. E. Daniels, took eight specimens on 

 June 20, 1902. They were found on open, sparsely vegetated sandy 

 tracts, about a fourth of a mile back from the shore of Lake Michi- 

 gan. Nothing distinctive of their habits was noted. One of the 

 females taken has the inner wings pinkish or coral red, as in tuher- 

 culatvs; two have them orange red, the others, yellow. Of the four 

 males, two have yellow and two orange colored wings. This is the 

 most eastern record for the species, its range, according to Scudder, 

 being from Moline, Illinois, westward to the Rocky Mountains. It 

 probably occurs in this State only in the sand-covered area of the 

 northwestern portion.

A rather bulky and short-bodied form. Vertex convex, the disk 

 indistinct, and sloping downward, broader than long in both sexes, 

 the lateral carinoe dull, low; the median carina extending to front bor- 

 der, and with a cross carina dividing the disk into four sub-equal 

 portions, the front pair being the more distinct; lateral foveolge, shal- 

 low, elongate triangular. Frontal costa broad, flat, punctate, slight- 

 ly sulcate just below the ocellus. Antennte about as long as head and 

 pronotum in the female, a third longer in the male. Pronotum with 

 the disk flat or nearly so, the metazonal portion not greatly widened, 

 the hind margin obtuse-angled, the surface bearing numerous low, 

 oblong or longitudinal, glistening tubercles; the median carina low, 

 cut very near the middle l)y the principal sulcus; the lateral carinas 

 distinct on the metazona; tlic lateral lobes of meta^ona densely punc- 

 tate. Tegmina relatively broad, exceeding the abdomen in both 

 sexes. Hind femora moderately slender, equaling or surpassing the 

 abdomen by one-fourth their length, the basal half depressed, dilated.
