scutellar area overrunning into and including the third or fourth interval 

 and back to a point just over the convexity diffusely punctate ; there 

 is also a slight disturbance about the seventh interval at the side, 

 the remainder is regularly punctate striate and usually a moderately well- 

 defined shield, marginal stria very lightly curved at humerus and almost 

 straight behind, lobe small, black, edged with a row of marginal punc- 

 tures; body below' dark, with the epimera, abdomen and pygidium 

 more or less picked out in yellow or livid, the $ 's more so than the ^ 's; 

 legs yellow, with indefinite lighter spots on thighs. 



Prescott, Arizona, 2 <$ 's, 3 9 's- Type coll., Bowditch. 



I also refer to this species three specimens from Provo, Utah, which 

 are somewhat larger than the foregoing and with the elytral U-maik obso- 

 lete or wanting and the legs with dark marks on the thighs ; and one ^ 

 example from San Bernardino Mts., California, which is black on the body 

 beneath, except the epimera and spots on the pygidium. 



Pachybrachys Sanrita, nov. sp. — Size rather large, stout, livid or red- 

 brown, with bright yellow spots and broken punctate striate elytra. 

 Length 3-4 mm. 



Head nearly flat, yellow, with vertex and middle branched spot, bases 

 of antenna? and edge of labium livid, antennae yellow, darker towards the 

 tip, barely reaching the middle of the body in $ , to about the hind coxa 

 in <$ , eyes distant ; the thorax finely punctured, broad, distinctly nar- 

 rowed towards the front, yellow with M in livid broadly marked, and 

 noticeably long median yellow line ; depressed behind, with a distinct 

 antescutellar lobe and depressed area in the ends of the M arms, sides of 

 thorax just barely deviated from a straight line in <^ , incurved towards the 

 rear, plainly angulate in ? ; elytra yellow, broad, somewhat depressed, 

 punctures closer than the thorax, confused in the scutellar region, third 

 and fifth intervals fairly well defined, then all are broken up to the two 

 side intervals, which are broad and somewhat irregular, the punctures 

 show a tendency to a biseriate arrangement, which is especially noticeable 

 at the base ; the standard spots suffused into livid transverse bands with 

 the edges diffuse in places, leaving two spots on either side, the tip, the 

 base keel (and interval roots from it) and a small sutural shield prominent 

 bright yellow ; the marginal stria very moderately curved round the 

 humerus, sinuate in rear, lobe wide and well marked with a row of strong 

 punctures on the curve, below livid brown, with the epimera, sides 

 of abdomen and pygidium picked out in whitish, prosternum sulcate, 

 legs yellowish-red, with light spots on ends of the thighs.
