About the size of, and most nearly related to, the A. caeruleipennis 

 Bruner, which occurs most abundantly somewhat to the southward 

 of the habitat of the present species. Conspersipennis is a pale 

 testaceous insect, which is strongly and quite evenly conspersed 

 throughout with dull brown. 



Of medium size and robustness, noticeably a little more stoutly 

 built than either cceruleipennis or nebulosa, the body and legs quite 

 strongly hirsute,, the tegmina less so. Head of moderate size, fully 

 as wide as the anterior edge of the pronotum; eyes fairly prominent, 

 but less so than in the species with which compared, the vertex between 

 them about as wide as the frontal costa in' both sexes, the fastigium 

 quite strongly depressed, about twice as wide as long. Frontal costa 

 plain and broadest above the ocellus, sulcate below, and continuous to 

 the clypeus. Antennae moderately robust, about as long (9) or a 

 litt'e longer (cf) than the head and pronotum combined. Front, 

 cheeks, pronotum, and pleura closely and strongly punctulate, and 

 also more or less decidedly rugose, the raised portions pallid. Tegmina 

 of moderate width and length. Hind femora robust. Hind tibiae 

 rather heavy, plainly expanded apically, the spines large and strong, 

 largely pallid, but with black tips. 



Length of body, cf , 16 mm., 9 , 20 mm.; of pronotum, cf , 3.15 mm., 

 9 , 4 mm.; of tegmina, d", 16 mm., 9 , 19 mm.; of hind femora, cf,
