I!22 THE CANADIAN ENTOMOLOGIST 



Nine £ 's, six $ 's, Opelousas, La., Georgia. 



Some small <$ 's resemble some examples of baj'u/us, Suff. Type coll., 

 Bowditch. 



Pachybrachys cro/tus, nov. sp. — Medium sized, variegated black and 

 yellow, rather smooth and semi-shining, very similar in size and general 

 appearance to me/anostictus, Suff. Length, 2-2^ mm. 



Head yellow, thickly, finely punctured with heavy frontal and vertex 

 marks, eyes distant, antennae dark red becoming black towards the end, 

 stout and in the £ reaching nearly the tip of the abdomen, thorax yellow, 

 somewhat narrowed in front, thickly and rather coarsely punctured, the M 

 taking the form of three heavy black stripes, nearly separate, of which the 

 middle one is entire to the rear margin and divided in front by a narrow 

 median yellow line attaining about the middle, transverse depression well 

 marked, lateral edge subangulate and sinuate behind ; the punctuation, 

 while to some extent avoiding the light portions of the thorax, is on the 

 whole, even and thick ; elytra yellow, semi-shining, brown punctate, striate, 

 with fairly regular costae on the rear convexity, the root of the third, most 

 of the fifth and the two side intervals : the standard spots show more or 

 less suffused, the rear ones having rather a tendency to form a band, 

 marginal stria lightly curved and lightly sinuate behind, lobe well de- 

 veloped and mostly occupied with a row of large punctures, body below 

 black with spots on the rear rings of the abdomen and pygidium, legs 

 brown with dark rings and light tips to femora. 



Cloudcroft, New Mexico, 15 examples. Type coll., Bowditch. 



The extent to which the intervals show on the elytra varies somewhat 

 and in one £ others than those mentioned above show, and some do not 

 show as many, but all show about the same behind, the small and most 

 regular $ 's approach similar is, nov. sp. , but are not as proportionately 

 long and cylindrical as that form. 



I have also 5 examples from the same locality which are almost 

 entirely black and where the punctuation seems closer, but as the black 

 parts of the ordinary forms are always the most punctured, a totally black 

 variety might naturally look more punctured than the type, so I call them 

 for the present identical. 



Pachybrachys Icevicollis, nov. sp. — Size large, form rather broad, flat, 

 elongate, shining, sparsely and finely punctured, especially on the thorax ; 

 black with pale thoracic margin and median line and a few specks of light 

 on the elytra. Length, 3^ mm.
