164 MEMOIRS ON THE COLEOPTERA 



apex of the moderately long mesosternal process rather free and 

 only slightly removed from the notably long tumid subparallel 

 metasternal projection, which, as well as the coxal cavities, is wholly 

 devoid of a fine bead-like margin. The metasternum is very short 

 behind the middle acetabula, and the rather thick hind tarsi have 

 the first joint about one-half longer than the second. The following 

 is a very distinct new species: 



Pontomalota luctuosa n. sp. Parallel, moderately convex, very 

 opaque, the abdomen more alutaceous and feebly shining, the minute 

 sculpture everywhere strong, the punctures not minute but shallow, 

 moderately close but rendered by the opacity rather indistinct, those of 

 the abdomen dense, stronger, asperate and distinct; color of the head 

 strongly, of the abdomen feebly, deep blue-black, of the pronotum deep 

 greenish-black, of the elytra evenly pale tawny-yellow, the legs pale, the 

 pubescence very short, stiff, pale; head transverse, nearly three-fourths 

 as wide as the prothorax, the eyes large, prominent, at only two-fifths 

 their length from the base, the tempora straight, parallel and less promi- 

 nent to the base; antennae short, only very feebly incrassate, very pale, 

 slightly infumate apically, the first three joints decreasing evenly in 

 length and thickness, four to six moniliform, about as long as wide, 

 seven to ten abruptly wider, increasing gradually, the latter evidently 

 transverse, the last small, compressed at apex, not as long as the two 

 preceding; prothorax large, about a fifth wider than long, with the sides 

 very evenly rounded, widest before the middle and narrowest at base, 

 the base transversely, the apex sinuously, truncate, the median line very 

 feebly impressed; elytra short, the sides arcuate and gradually diverging, 

 even at apex barely as wide as the prothorax, the suture three-fourths 

 as long as the latter; abdomen long, parallel, about as wide as the elytra, 

 with very thick margins, becoming thin on the fifth tergite, the tergites 

 one to five equal, the first four more or less feebly impressed at base 

 medially though not or barely at all laterally. Length 2.7-2.85 mm.; 

 width 0.63 mm. Queen Charlotte Islands (Massett), Keen. 



The nearest relative of this species is calif ornica Csy., but it is 

 much stouter, differs greatly in color and especially in the feebler 

 transverse abdominal impressions, which are all rather deep and 

 distinct throughout the width and more shining in californica. 



Strigota Csy. 



This is one of the most widely distributed of the American genera, 

 and it would be to some degree remarkable if some one of its numer- 

 ous species should not have been hitherto described under another 

 name; it belongs rather to the Gnypeta series than to any other, 

 but its general habitus is sufficiently distinctive.
