terior lobe punctate ; central portions of the sides levigate ; cross incisions 1 

 and 2 not reaching the median carina. Elytra narrow, covering about two- 

 thirds of the abdomen, lanceolate ; the two longitudinal veins strong, ap- 

 proaching at the apex, along the borders, the reticulate veins coarse. Wings 

 shorter than the elytra. 



Color (siccus). Dark ferrugineous. Lower angles of the face and sides of 

 the lip black. Tips of the elytra black. Apex of the wings dusky, rest trans- 

 parent. Two reddish spots inside the posterior femora ; tibiae transparent 

 red. 



Male. Similar in coloring only darker. Elytra black, somewhat paler at 

 the base ; wings transparent, cloudy at the apex (I think they are roseate 

 when living.) , 



Dimensions. Female. Length 1-5 in.; pronotum -32 in.; elytra -55 in.; 

 femur -95 in. ; tibia "80 in. Male. Length -87 in. ; pronotum -25 in. ; elytra 

 55 in. ; femur -62 in.; tibia -56 in. 



Hab. South Colorado and New Mexico, from Canon City south, near the 

 mountains ; mostly in the narrow vallevs behind the first range of parallel 

 hills called "Hog-backs." 



.B. FLAVO-FASCIATUM, nOV. Sp. 



Very much like B. nigrum in size and carving. 



Female. Central foveola of vertex very shallow, divided into two parts by 

 a median carina; frontal ridge convex, sparsely punctured. Pronotum differs 

 from previous species only in having the transverse incisions less distinct. 



Color (siccus). Yellow varied with brown. Head yellow ; lower angles of 

 the face black ; a very distinct yellow line, starting from the upper comer of 

 each eye, reaches the posterior margin of the pronotum, bowing inward near 

 the middle ; bordered on each side by an irregular dark brown line ; a dark 

 line borders each eye posteriorly. Median carina of the pronotum dark 

 brown or piceous-black ; the transverse incision black ; rest of the pronotum 

 brownish, palest on the sides. Elytra formed as in B. nigrum, brown, a pale 

 yellow stripe near the upper and lower margins of each, the upper divided 

 near the base ; three oblong yellow spots in a line along the middle, and a 

 few smaller spots near the apex ; reach the third abdominal segment. Wings 

 transparent, dusky at the tips. A brown stripe along each side of the ab- 

 domen, near the dorsum ; a yellow spot in it on each segment near the upper 

 border. Venter yellow. 



Male. Unknown. 



Dimensions. Female. Length 1-5 in. ; pronotum -38 in. ; elytra -50 in. ; 

 femur -85 in. ; tibia 76 in. 



Hab. Same as preceding, but a much rarer species. 



Remarks on Huxley's Classification of Birds. 

 BY T. HALE STREETS. 



In arranging and classifying the collection of birds' skeletons, crania, and 

 sterna in the possession of the Academy, I was induced to compare some 

 points in their osteology with the statements made by Prof. Huxley in an arti- 

 cle entitled "On the Classification of Birds," which appeared in the Proceed- 

 ings of the Zoological Society of London, 1867, Part II. 



In this article Prof. Huxley divides birds principally according to the mod- 

 ifications presented by the bones forming the roof of the mouth, namely, the 

 palatines, the maxillo-palatine processes, the pterygoids, the basi-pterygoid 

 processes, and the vomer. 



After these the sternum, clavicles, coracoids, and occasionally other points 

 claim attention as affording a basis for the classification. 



He makes three orders. The first contains a single bird, the extinct Archse-
