June, 1913] Roberts: Notes on Haliplid.e of America. 101 



The anterior of the double row of basal punctures is the shorter and 

 composed of smaller, irregularly placed ones, while in the posterior row they 

 are regularly placed and much enlarged towards the side margins. 



Elytra oval, widest at middle, gradually rounded to exterior angle and 

 with the apices slightly oblique, not sinuate, interior angles obtuse ; striae 

 composed of deep blackened punctures, largest at base and gradually diminish- 

 ing to apex ; sutural interspace with a single row of small punctures closely 

 and evenly placed, the remaining intervals having similar ones more widely 

 separated ; maculate with elongate spots or dashes of black situated as fol- 

 lows : one nearly touching the base between the third and fourth striae, one 

 subhumeral between the fifth and sixth, one obliquely below this between the 

 third and fourth, three below this last, placed horizontally, the inner extend- 

 ing in a patch from suture to second stria, the middle between the fifth and 

 sixth and the outer between the seventh and eighth, below these four more 

 subapical between the second and third, fourth and fifth, sixth and seventh, 

 this last \ery short, and a patch from eighth to lateral margin ; suture very 

 narrowly black from base to apex, base immaculate. Underside of body 

 ferruginous with the joints of legs and posterior margins of abdominal seg- 

 ments infuscate. 



Prosternal process flat, scarcely wider at base than apex, somewhat con- 

 stricted before front coxae, apex finely margined, with deep, closely placed 

 punctures diminishing towards the apex. Mid-metasternum almost flat, with- 

 out margins, not tumid in front, sometimes with a slight depression at center ; 

 punctuation the same as that of the prosternum with the usual smooth space 

 at center. Hind coxae with moderate-sized, deep punctures evenly placed ; 

 apices broadly rounded exteriorly, nearly truncate from middle to suture. 



Front and middle tarsi of male with the joints not much shorter than 

 those of the female, slightly compressed and quite evidently, though not 

 strongly, pedunculate. 



Male and female types from Tyngsboro, Mass. (Fredk. Blanch- 

 ard) in my collection. 



Dr. Leconte separated this species under the above name in 

 manuscript, but never published the description, being perhaps de- 

 terred by Mr. Crotch's criticism that it was only a dark form of 

 cribrar'ms. It is unquestionably distinct from that species. 



Twenty-eight examples before me vary little in form, punctuation 

 or structural characters, but there is a wide range in maculation, the 

 tendency being a reduction in the length of the spots or a fading 

 away even to the complete obliteration of some of them. 



In the male type the extreme intensity of marking is illustrated, 

 while in the female type the spots are all reduced, the basal entirely 

 wanting, and of the three submedian ones the inner is not coalescent 

 with the suture and the outer has entirely disappeared. I have, how-
