170 MEMOIRS ON THE COLEOPTERA 



Gnypeta modica n. sp. Rather stout and convex, polished, piceous- 

 black, the elytra much paler, rufous, blackish at base, the legs rather 

 pale, piceous; punctures very minute and inconspicuous, sparse, closer 

 and larger toward the sides of the head, not more visible on the elytra, 

 slightly more distinct on the abdomen, where the three tergitical im- 

 pressions are sprinkled with coarser separated punctures; pubescence 

 pale, rather long and coarse; head but little wider than long, as wide as 

 the prothorax, the eyes moderately prominent, at a little less than their 

 own length from the base, the tempora rapidly arcuato-convergent 

 behind them to the base, becoming parallel just behind the more promi- 

 nent eyes; antennae moderate in length, piceous, slender, rather rapidly 

 and distinctly thick distally, the first joint stouter and much longer than 

 the second, the latter equal to the third, fourth nearly one-half longer 

 than wide, the joints thence rapidly larger, the tenth two-fifths wider 

 than long, the last conical, acute, as long as the two preceding; front 

 feebly impressed at the centre; prothorax a fourth wider than long, very 

 convex, widest near anterior third, where the sides are rather broadly 

 rounded, thence becoming strongly convergent and more nearly straight 

 to the base, the surface unimpressed, having before the scutellum two 

 small and approximate, almost perforate fovese; elytra large, rather 

 transverse and convex, parallel, two-fifths wider and a third longer than 

 the prothorax, the humeri broadly and transversely exposed at base; 

 abdomen a good deal narrower than the elytra, parallel, with nearly 

 straight sides, the first tergite shortest, the fifth large, fully one-half 

 longer than the fourth. Length 2.2 mm.; width 0.56 mm. Arizona 

 (Tugson). 



Very greatly resembles a Euliusa and constituting perhaps one 

 of the bonds between the two groups; it is distinguishable at once 

 from Euliusa pimalis, inhabiting the same locality, by its smaller 

 size and narrower form, less prominent eyes, less angularly promi- 

 nent sides of the prothorax anteriorly and the unimpressed median 

 basal part of the pronotum, rather shorter antennae and especially 

 by the coarse punctures scattered over the tergitical impressions, 

 these being smooth and punctureless in pimalis. 



The Pomona example, which I placed with the Mendocino and 

 Sonoma linearis in my revision of this genus (1. c., p. 200) is really 

 not identical but may be attached to linearis as a variety as follows : 



Gnypeta sensilis n. subsp. Form and coloration nearly as in linearis 

 but rather more convex throughout and with more close-set punctures, 

 the long and gradually incrassate, piceous-brown and basally gradually 

 pale antennae nearly similar, but with a longer terminal joint, this being 

 as long as the two preceding joints combined; prothorax differing de- 

 cidedly, being less parallel and less transverse, in fact only just visibly 

 wider than long, with the sides more rounding and converging anteriorly, 

 so that the apex is more evidently narrower than the base though, be-
