SOME COLEOPTERA FROM CENTRAL AMERICA. 299 



only the apical and subapical bristles are prolonged, on the second 

 only the apical one (tig. 6, male), both bristles of the subapical pair 

 being short, the long apical bristle of the male moreover not reaching 

 beyond the claw. 



Modified segments. — $. The body of the clasper (fig. 4, CI) is 

 much shorter than in B. bivirgis, the manubrium (M) much more 

 directed downward, and the process P of the clasper as well as the 

 movable process F are slenderer. Process F is much longer than 

 its distance from the manubrium. The horizontal arm of the ninth 

 sternite (ix. st.) is broader than in B. bivirgis. 



5 . The antepygidial bristles are longer than in B. bivirgis, and 

 the apical lobe of the seventh sternite (vn. st.) is much more produced 

 than in that species (fig. 5). The eighth tergite (vm. t.) has four 

 bristles below the stigma, the lower one being very long, and a subapical 

 row of eight. Proximally to this row there are from three to five 

 bristles, the segment also bearing a row of five or six bristles on the 

 inner surface. The stylet, as in the preceding species, is almost 

 perfectly cylindrical. The receptaculum seminis (r. s.) closely 

 resembles that of B. bivirgis. The wall on the ventral side of the 

 " tail " has partly collapsed in both our mounted specimens, as drawn.

SOME COLEOPTERA FROM CENTRAL AMERICA. 



By T. D. A. Cockerell. 



When recently at the U. S. National Museum, I took occa- 

 sion to work over some Coleoptera from Central America, 

 principally collected by my wife in Guatemala. While doing 

 this I was much indebted to Mr. Herbert S. Barber for his kind 

 assistance. I give here a few notes which may be of interest. 



Brachyacantlia bistripustulata (Fabr.). — Bocas del Toro, 

 Panama (E. Bethel). As this did not agree very perfectly with 

 Leng's description (Bull. Amer. Mus. Nat. Hist. xxx. p. 296), I 

 took occasion to compare it with authentic specimens, and found 

 that Leng's description was inadequate in regard to the struc- 

 ture of the legs ; so much so, that one might be misled into 

 thinking he had a new species. I made an entirely new de- 

 scription from my specimen, and give it here : — 



? . Length, 3| mm., broad oval, dorsally shining black, with 

 light orange spots ; elytra with small evenly scattered punctures, and 

 between them some excessively minute ones, only visible with a 

 high power of the compound microscope (all this is essentially as in 

 B. ursina) ; thorax similarly sculptured, but the punctures denser in 

 the median field ; front of head punctate, and minutely (micro- 

 scopically) rugulose between the punctures ; eyes a fine dark green ;
