and of equal width, not in the least serrate, 3-5 decreasing in length, 3 a little 

 longer than wide, 5 wider than long, 6-8 strongly transverse and compactly 

 joined, 9-11 extremely slender and elongate, 9 about 6 times as long as wide 

 and fully as long as the preceding joints combined, 10 a little lohger and feebly 

 arcuate throughout its length, 11 straight, still longer, 9-11 combined nearly 

 as long as the elytra. Head deflexed, finely sparsely punctate; eyes round, 

 prominent. Prothorax about as wide as long, convex, disk a little gibbous 

 profile, side margins narrowly flattened, subparallel medially, narrowed a little an- 

 teriorly posteriorly sinuately curved into the rounded base, the edge finely serrulate 

 anteriorly, surface finely, not closely punctate. Elytra scarcely wider at base than 

 the protliorax, 2^/2 t*mes as long as wide, disk with feebly impressed rows of 

 fine punctures, the striae a little deeper at sides. Legs, especially the tibiae 

 and tarsi, very slender, basal joint of hind tarsus scarcely as long as the next 

 two, fourth tarsal joint not perceptably emarginate. 



Length 2.85 mm.; width .9 mm. 



Described from a single male specimen taken at San Diego, California, 

 7-16-1909, by Mr. George H. Field. 



Although very different in facie's from the two known species of this genus, 

 because of the smaller size and more slender build, there is really little upon 

 which to found a new genus, the most conspicuous feature being the extreme 

 length of the three outer joints of the male antennae. In this connection it 

 should be remembered that thfere are numerous instances of markfed variation 

 in antennal structure within generic limits in this family, and in the genus 

 Oligomerodes the two known species differ appreciably in this respect, the 

 antennae in catalince vary considerably from occidentalis in the direction of the 

 present species. 



Hadrobregmus Thoms. 



H. subconnatus, sp. nov. 



Elongate, parallel, moderately convex, brown, opaque, with short, fine, 

 sparse yellowish appressed pubescence. Second and third joints of antennae 

 smallest, the latter narrower, joints 4-8 subequal, not quite as wide as long, 

 9-11 subequal to all the preceding in the male, joint 9 about 2^/2 times as long 

 as wide and a little longer than the two preceding, joint 10 similar to 9 but 

 scarcely as long, 11 three times as long as wide. In the female joints 9-11 

 are a little shorter than all those preceding, 9 and 10 each scarcely twice as long 

 as wide. Prothorax, when viewed at right angles to the plane of its side margins, 

 is obviously though not greatly wider than long, suboctagonal in outline, sides 

 straight and nearly parallel medially, obliquely narrowed before and behind, 

 the posterior obliquity sinuate, hind margin evenly arcuate, front margili with 

 a short, feeble median sinuation; surface, like that of the head, finely rugulose 

 and feebly granulose; front angles, posterior margin and median line impressed. 

 Elytra slightly wider at base than the prothorax, sides feebly sinuate before 

 the middle, slightly dilated posteriorly, apex rather narrowly truncate; disk 

 punctate-striate, the interspaces finely rugulose, subequal in width to the striae, 

 nearly flat toward the suture, a little convex laterally. Body beneath alutaceous 

 and minutely punctulate; ventral segments subconnate at middle, first segment 

 short, 2-4 subequal, 5 longer; last two ventral sutures anteriorly arcuate, the
