Baring 471 



from base to the tubulate apex, which is nearly three-fourths as wide as 

 the base; punctures small but deep, sparse, separated by two or three 

 times their diameters, a little larger and closer laterally, the smooth median 

 line traceable in basal half; elytra three-fifths longer than wide, barely 

 wider than the prothorax and fully twice as long, the sides parallel and 

 nearly straight, slightly converging and partially sinuate posteriorly to 

 the obtusely rounded apex; striae deep but not coarse; intervals fully 

 three times as wide as the striae, each with a single line of very fine and 

 widely spaced punctures. Length (9) 2.6 mm.; width 0.75 mm. 

 Guatemala (Yzabal, — elev. 100 ft.). One specimen. 



This species is peculiar in the form of the elytra, the posterior 

 partially sinuous obliquity toward the obtusely rounded apex, 

 exactly as in Centrinogyna, indicating again that Anacentrus is a 

 genus rather closely allied to Centrinogyna, but differing in the 

 small size of the body and in having only the tip of the oblique 

 pygidium exposed in the male. I cannot find that either of these 

 Guatemalan species was described by Mr. Champion, and I kept 

 no record of the source from which they were received many years 

 ago. 



Dirabius n. gen. 

 The body here is much larger than in the preceding genus and is 

 subglabrous, the squamules above and beneath always minute, 

 grayish, very sparse and inconspicuous, the integuments at first 

 view being glabrous. The beak is rather long and slender, cylindric 

 and sometimes almost straight in the female, but, unlike the pre- 

 ceding genus and more nearly as in Odontocorynns , it becomes thick 

 and strongly sculptured in the male; the surface of the beak joins 

 the head without constriction but there is generally a frontal punc- 

 ture. The mandibles are decussate, with large internal tooth, the 

 antennae slender, the first two funicular joints notably elongate and 

 often subequal and the club peculiarly narrow, gradually pointed 

 and with long basal joint; the anterior coxae are well separated and 

 the prosternum simple in both sexes. The type of the genus is 

 Centrinus rectirostris Lee, which I erroneously referred to Linino- 

 haris in my revision, Centrinus calvus Lee, from Georgia and 

 Florida, also belongs to this genus, but is not now represented in my 

 collection; the others at hand may best be treated in tabular form 

 as follows : 



Body broader and oblong, convex, the prothorax sometimes inflated at 

 the sides. [Subg. Dirabius in sp.] 2
