Baring 387 



The type of this species is a female and is very much smaller 

 than senilis Gyll.; it differs also in the more narrowly oval outline 

 and much finer sculpture. The black elytral maculation takes the 

 form of a regular transverse submedian fascia from side to side, 

 interrupted only at the suture and a broader one near the apex, also 

 suturally interrupted and not clearly attaining the sides. The 

 beak in the female is very much shorter, with the antennae less 

 post-median in insertion than in senilis. 



The following are two additional species of this genus: 



*Geraeus omissus n. sp. — Elongate-rhomboidal, rather convex, slightly 

 shining, dark piceous-brown in color in the type; beak in the female 

 evenly arcuate, slender, gradually somewhat thickened, as well as 

 laterally sulcate and feebly punctate, basally, as long as the elytra, the 

 long slender antennae inserted at the middle; prothorax a third wider 

 than long, the sides evenly and rather strongly arcuate, becoming 

 parallel basally, the apical tubulation strong, three-sevenths as wide as 

 the base, the basal lobe rather abrupt; punctures coarse, close but not 

 in mutual contact, each with a long and slender, yellowish-white scale; 

 elytra arcuately acuminate from the base, much wider than the prothorax 

 and not quite twice as long; striae moderate, rather deep, minutely punc- 

 tate; intervals three times as wide as the striae, rather finely, sparsely 

 and confusedly punctate, the punctures bearing each a long slender 

 yellowish scale, coarser than those of the pronotum, and replaced in a 

 dark submedian and subapical fascia, both interrupted suturally and 

 not attaining the sides, by finer obscure fulvous squamules; under 

 surface coarsely punctate and with linear but coarser and closer pale 

 squamules; legs long and rather slender. Length (9) 4.5 mm.; width 

 1.8 mm. Mexico (Temax, in N. Yucatan), — Gaumer. 



A single example was kindly communicated by Mr. Champion. 

 This species differs from senilis, which is well represented before 

 me from Guerrero, Jalapa and Managua, in its slightly smaller 

 size, distinctly narrower form and especially by the coarser and 

 more sharply and individually defined punctures of the prothorax. 

 The antennae of the female are inserted at the middle of the beak 

 and not well behind the middle as they are in senilis. 



*Geraeus bellax n. sp. — Elongate-rhomboidal, rather convex, slightly 

 shining, piceous-black; beak nearly as in the preceding, slender, as long 

 as the elytra, with the antennae inserted at the middle (d^) or at three- 

 sevenths ( 9 ) ; prothorax a fourth to third wider than long, the con- 

 verging sides evenly arcuate to the short and feebly defined apical tubu- 

 lation; punctures somewhat coarse but shallow, dense and sometimes 

 subcoalescent, the lustre dull, the vestiture of long slender whitish scales 

 distinct but loose; elytra arcuately acuminate, with rather tumid humeri,
