margin, strongly punctate except a linear transverse area on disc ; paired 

 basal impressions wanting. Prosternal ridge margined, convex transversely 

 and longitudinally, sharply declivous in front, sides nearly straight, slightly 

 constricted in the region of the prothoracic legs, punctate. Abdominal seg- 

 ments smooth and shining, punctate at their apices. Legs pale yellow ; pos- 

 terior coxEe punctate, rounded posteriorly, reaching the fourth segment of the 

 abdomen. 



Elytra with large, well-defined black spots and margins (Plate XV). 

 There is great variation in these markings, the spots on one elytron differing 

 considerably from that of the other of the same insect. Each elytron has ten 

 rows of large punctures of the same color as elytra ; intervals, each with a 

 fairly well-defined row of small punctures ; apices of elytra obliquely truncate, 

 slightly denticulate. 



Habitat. — Maine and Ontario west to Wisconsin and Colorado, 

 south to Georgia and New Mexico. 



Haliplus cribrarius Leconte. 



Haliphis cribrarius Leconte. Lake Superior, Agassiz and Cabot, 1850, p. 212. 



Color pale yellow with a black spot on head, one on pronotum, and sev- 

 eral on the elytra. Length 4.75-5 mm. 



Head punctate except a narrow transverse area in front of the black spot 

 on vertex ; a black crescent-shaped spot behind and between the eyes ; eyes 

 broadly oval in outline ; labrum emarginate, rounded at the sides, a row of 

 small setae on the anterior margin ; antennae pale yellow. 



Pronotum with a prominent black spot on its anterior margin, punctate, 

 with two fairly well-defined rows of large, black, basal punctures, anterior 

 row not reaching the margin, remaining punctures of the same color as the 

 pronotum ; disc sparsely punctate. Prosternal ridge not margined, flat trans- 

 versely, convex longitudinally, strongly punctate, steeply declivous in front, 

 sides constricted in the region of the prothoracic legs. Abdominal segments 

 smooth and shining, fourth and fifth with a transverse series of punctures 

 near the middle. Legs pale yellow to rufous ; posterior coxae rounded behind, 

 strongly punctate, reaching the fourth segment of the abdomen. 



Elytra pale yellow with ten rows of large black punctures ; intervals, each 

 with a definite row of small punctures ; black sutural stripe narrow, not 

 extending beyond first row of small punctures ; apical margins obliquely 

 truncate. 



Habitat. — Labrador (West St. Modest, one specimen) ; New- 

 foundland (Coast Plain, Bowditch ; Bay of Islands, Leng) ; Canada 

 (Nova Scotia) ; New Hampshire (Mt. Washington, Lakes of Clouds, 

 Bowditch); New York (Ithaca); Ind. (Pine, Lake Co., Blatchley).
