Sept., 1912.] Matheson : Haliplid^ of North America. 167 



Pronotum pale yellow with a rounded rufous spot on its anterior margin, 

 punctate, the disc sparsely so. Prosternal ridge margined, not grooved, con- 

 vex laterally and longitudinally, sharply declivous in front. Abdominal seg- 

 ments smooth, shining, each with a row of punctures on its posterior edge. 

 Posterior coxae punctate, rounded behind, reaching the fourth segment of the 

 abdomen. 



Elytra with well-defined black spots (Plate XV) ; each with ten rows 

 of shallow punctures of the same color as the elytra ; intervals with fairly 

 well defined rows of small punctures ; apices obliquely truncate, not sinuate, 

 denticulate. 



This species is readily separated from H. borealis Lee. by the 

 apices of the elytra not being sinuate and from H. Iczvisii Crotch 

 by the presence of the rufous spot on the apex of the pronotum and 

 the well-defined arrangement of the black spots on the elytra. 



Described from two specimens from Texas. From the collection 

 of the Michigan Agricultural College, East Lansing, Mich.
