faintly embrowned and distinctly indented. Eostrum dull testaceous, 

 piceous at tip, reaching upon the second ventral segment. Cranium 

 scooped out, the anterior edge sharp and curved upward ; the surface 

 coarsely and irregularly punctate in the depressed spaces, but more 

 regularly on the rounded central lobe, this lobe deeper brown, fuscous 

 behind, and with a medial pale line 5 ocelli red ; occipital margin trian- 

 gularly excavated to receive the produced triangular front of the mid- 

 dle of the pronotum, the margin each side elevated, and the base of 

 median line elevated. Pronotum a little shorter than in A. iMrallelay 

 Say, the lateral margin deeply sinuated and not slanting so narrowly ; 

 surface a little clouded with brown, distinctly and irregularly punctate, 

 the punctures more dense anteriorly and on the sides; the disk con- 

 vexly elevated, deeply sunken before the anterior margin, and twice 

 depressed each side, the middle line pale, slender, feebly elevated. 

 Scutellura pale ochreous, finely punctate, depressed, and infuscated in' 

 the middle, and with the tip paler and very acute. Legs pale testa- 

 ceous, the femora more or less clouded with brown, and the incisures of 

 the tarsi piceous. Hemelytra pale brown to beyond the middle, the 

 apical portion brownish-white, with dark nervures ; base, an entire 

 oblique band before the middle, and a similar shorter one behind the 

 middle dark brown, both these bands margined posteriorly with whitish, 

 coalescing spots, some of which are occasionally carried back upon the 

 middle of the disk. Wings brownish-white. Tergum ochreous ; venter 

 and pectus pale testaceous, the latter sometimes with brown spots on 

 the middle coxse and disks of the posterior pleural segments. 



Length to tip of hemelytra, 8J to 12 millimeters. Width across base of 

 pronotum, 3 to 3^ millimeters. 



Collected in Colorado and Utah by the surveys ; but sent to me on 

 several occasions, from near San Francisco, by the kindness of James 

 Behrens. 



It varies so much in depth, of colors and pattern of marking that it is 

 almost impossible to characterize the varieties. One of these varieties 

 is almost a fac-simile of the Euroj)ean A. corticea, Germar.
