HARPALIN^; 113 



(cf), opaque (9), the apices obliquely truncate, slightly sinuate, the 

 third interval with two impressed punctures [whether on each elytron or 

 the two combined not stated]; trophi and mandibles, palpi and labrum, 

 limb of the prothorax and elytra narrowly, the margins reflexed, and the 

 antennae and legs rufous. Length 8-9 mm.; width 3.3-4 mm. Alaska 

 (Kodiak Island). 



Evidently different from any known to me; the language referring 

 to the elytral puncture is puzzling. 



H. ventralis Lee. Oblong-oval, parallel, subdepressed, nigro-piceous 

 above; head smooth, the frontal suture distinct, the frontal impressions 

 minute; mouth, antennae and palpi rufo-piceous; prothorax one-half 

 wider than the head, not shorter than wide [!], quadrate, anteriorly 

 slightly emarginate, with the sides rounded anteriorly, posteriorly nearly 

 straight, the base truncate, with the hind angles perfectly right, obsoletely 

 explanate; transverse impressions almost obsolete, the stria fine, the 

 basal foveae linear, not deep; elytra feebly sinuate at tip, striate, the striae 

 fine, deeper posteriorly, the intervals flat; under surface and legs wholly 

 pale rufo-piceous. Length 8.7 mm.; width 3.7 mm. Near Long's Peak. 



The statement in regard to the form of the prothorax of this 

 species prevents the assignment to it of any known to me. No 

 mention is made of any peculiarity relating to the abdomen or 

 hind body, as the name would seem to imply. 



H. opacipennis Hald. (Ophonus) Oval, glossy, chestnut-brown 

 beneath and upon the middle and posterior thighs; antennae, palpi, 

 margin of the labrum, intermediate and posterior tibiae and tarsi and 

 anterior legs rufous; head with a small round indentation upon each side 

 between the antennae; pronotum much wider than long, transversely 

 rugulose, with the basal impressions rugose, shallow, each with a very 

 slight fossula; dorsal lines faint; elytra finely and simply striate; inter- 

 stices flat, with a puncture upon the third one; tip slightly sinuate; 

 surface sericeous. Length 9 mm. Southeastern Pennsylvania. 



I cannot refer any one of the new forms here described to this 

 species. Although both plenalis and latebricola have the opaculate 

 elytra, the legs are clear and uniform testaceous throughout. 

 Opacipennis may come just before plenalis in the table. 



H. carbonatus Lee. Elongate-oblong, being somewhat as in cautus 

 (advena Lee.) but with basal thoracic angles less rounded; head obtuse, 

 the eyes moderately prominent; prothorax wider than the head, shorter 

 than wide, slightly narrowed posteriorly, the sides broadly rounded, 

 obsoletely explanate posteriorly, the hind angles right, with their tips 

 rounded; basal foveae small, not at all deep and sparsely punctate; 

 elytra (9 ) opaque, the apices not at all sinuate; striae impunctate, the 

 intervals slightly convex; antennae and palpi piceo-rufous. Length 

 10 mm. Saskatchewan.
