636 Coleopterological Notices, IV. 



Arizona; Southern California. 



The general characters of the above description are drawn from 

 the female ; in ihe single very small male before me, the prothorax 

 is quite distinctly wider than long, with the apex three-fifths as wide 

 as the base. The great disparity in the length of the beak is, how- 

 ever, the only very prominent sexual difference. In certain general 

 characters of sculpture and vestiture, seclusa makes an excellent 

 transition from the normal forms of this subgenus to grisea.

12 Limnobaris grisea Lee. — Proc. Am. Phil. Soc, XV, p. 312 (Cen- 

 trinus). 



Oblong-oval, moderately convex, piceous-black, the elytra and 

 legs rufous; vestiture consisting of large elongate-oval yellowish- 

 white scales, not contiguous beneath except in anterior two-thirds 

 of the met-episterna ; on the pronotum they are still more elongate, 

 denser near the sides and finest and sparsest at lateral fourth ; on the 

 elytra they are broadly oval and unevenly disposed in strongly 

 marked lines along the intervals, the line of the third interval 

 being especially wide and conspicuous. Head glabrous, minutely, 

 sparsely and feebly punctate, the impression very feeble ; beak 

 cylindrical, rather stout, evenly and rather strongly arcuate, as 

 long as the head and prothorax in the female, but only as long as 

 the latter in the male, the basal joint of the funicle as long as the 

 next four together, the second as long as the next two, outer joints 

 very short and transverse ; club in the male large, densely pubes- 

 cent, as long as the six preceding joints together, oval, pointed, the 

 rings decreasing abruptly in transverse diameter, the basal joint 

 much less than one-half the mass. Prothorax coarsely, closely 

 punctate, two-thirds wider than long, the sides subparallel in basal 

 two-thirds, then strongly rounded and rapidly convergent but not 

 distinctly constricted to the apex, basal angles obtuse, the mes- 

 epimera strongly exposed from above. Scutellum rather large, 

 quadrate, glabrous, but indented and setose at each side. Elytra a 

 little wider than the prothorax and about twice as long, hemi-ellip- 

 tical in outline, the striae fine, the intervals strongly, confusedly 

 punctate and from two to more than three times as wide as the 

 grooves. Length 3.4 mm. ; width 1.65 mm. 



The three specimens before me are from Arizona and New Jersey ; 

 it was originally described from Texas. In the female the antennal
