ALOPHID.E. 117 



gradually shorter, four to six equal, ^leventh -wider but only a little longer, 

 club oval, pointed, not as long as the three preceding united. 



Prothorax rather small, sides broadly and feebly lobed behind the eyes, 

 narrowed before and behind, not wider than long, truncate at tip and base; 

 coarsely granulate and punctured; transversely impressed beneath, near 

 the tip. 



Elytra oval convex, more than twice as wide as the prothorax in 9. 

 elongate oval and one-half wider than the prothorax in (^, with nine rows 

 of shallow punctures, interspaces rugose and sparsely punctured, nearly 

 glabrous, with a few scattered scales in the larger punctures, humeri 

 rounded, scutellum very small, pubescent. 



Legs moderately long and slender, thighs somewhat clubbed, and sinuate 

 towards the tip; front tibiae subsinuate on the inner side, curved inwards 

 and mucronate at tip; the other tibiae are expanded somewhat at tip, trun- 

 cate and feebly mucronate. Tarsi shorter than the tibiae, claws separate. 



T. ater, n. sp. 



Black, nearly opaque (cJ*), or dull ( 9 )> beak and head strongly not 

 densely punctured; prothorax punctured towards the middle, coarsely 

 granose at the sides, with a narrow sometimes indistinct dorsal line; elytra 

 rugose and punctulate, with rows of larger punctures in which are scat- 

 tered pale scales; beneath with small scattered patches of ochreous scales. 

 Length 12 — 14 mm.; .45 — .6 inch. 



California: Dr. Horn and Mr. Ci-otch. The patches of scales beneath 

 are on the prosternum in front of the coxae; the outer angle of the metas- 

 ternuni, and at the sides of the ventral sutures. This singular insect has 

 some resemblance in appearance to Molytes, but is moi'e slender, and the 

 characters totally unlike. The elytra are more strongly declivous behind 

 than in the other genera, being in fact perpendicular towards the tip. 



PLINTHODES n. g. 



Beak as in Triglyphus, except that the apical wings are a little wider, 

 and the lateral grooves not so deep, there is also a vague groove between 

 the medial and lateral grooves. Antennae with the second joint of the 

 funicle longer than the first, and together equal to the four followingunited: 

 three to seven equal, the seventh a little wider, club oval pointed, as long 

 as the three preceding. Prothorax not narrowed behind, rounded and 

 narrowed on the sides in front, postocular lobes broad, feeble; transversely 

 impressed beneath, and at the sides near the tip. 



Elytra oblong-oval, wider in 9 than in (^, nearly truncate at base, 

 slightly impressed on the sides behind the humeri, which are rounded but 

 distinct, tip gradually declivous (but not perpendicular); very densely 

 scabrous, with rows of large deep punctures; pubescence fine, sparse, with 

 small scattered narrow pale scales, and two small spots on each elytron; 

 scutellum clothed with ochreous scale-like hairs. Legs as in Triglyphus. 



The beak is very densely punctured; the prothorax the same, mixed with 

 granules at the sides; the under surface is pubescent, densely but not
