96 EEOTYLIDJE. 



The antennae are as long as or a little longer than the head and thorax; the two basal 

 joints yellow, the third pitchy or varied with yellow and black, the fourth and fifth 

 elongate and fusiform, the sixth and seventh a little shorter and more obconic, the 

 eighth obconic, scarcely forming part of the club ; the last three joints wider, produced 

 on each side ; the apical joint about as wide as long, but compressed and contracted at 

 the tip. 



Three specimens from Bugaba agree very closely with the description I have given, 

 and in size ; a fourth is much smaller, and has not the fuscous punctures, but the 

 striae rather more distinctly impressed ; while one specimen, also from Bugaba, has the 

 elytra rather more produced at the apex, entirely smooth and unicolorous, but with 

 numerous most minute punctures both in the obsolete strise and irregularly in the 

 interstices. This species is allied rather closely to B. concolor, but appears (according 

 to a specimen of that species from Reiche's collection) to differ from it in having the 

 thorax shorter, more convex and shining, and (according to Lacordaire's description) by 

 the striae and punctures being more effaced. 



9. Brachyspheims striatipennis. 



Oblongo-ovatus, convexus, flavo-testaceus, nitidus ; antennis (basi excepta), scutello tarsisque nigricantibus ; 

 elytris tenuiter distincte punctato-striatis, striis fere integris, punctis fuscis. Long. 6|-8 millim. 



Hab. Panama, Bugaba (Champion). 



This species is so very near to B. brevicollis that it will suffice to point out the 

 differences : — The antennae are thinner ; the thorax is not quite so short, and less 

 convex, and the median lobe at the base is less distinctly produced and truncate ; the 

 punctures of the elytral striae are more distinctly impressed ; and the legs have only the 

 tarsi infuscate. B. striatipennis appears to agree very closely with Lacordaire's 

 description of B. concolor ; but to differ by not having the tibiae infuscate, and by the 

 striae being continued almost to the apex of the elytra. It differs also from the repre- 

 sentative of that species in Crotch's collection. 



10. Brachyspheims pallidipennis. 



Oblongus, elytris longioribus, testaceis, nitidus, fere glaber ; protboraeis disco convexo, rufo-testaceo, lateribus 

 late et elytris pallidioribus, his fusco punctato-striatis, vix impressis; antennis (articulis duobus primis 

 exceptis), scutello, tibiis tarsisque nigris. Long. 9 millim. 



Hab. Panama, Bugaba (Champion). 



This species is exceedingly close to, and difficult to separate satisfactorily from, 

 B. brevicollis. If, however, great latitude is not to be allowed to proportionate form 

 in this genus, the longer and rather flatter thorax, and the much longer, more pointed, 

 and gibbous elytra indicate a distinct species. In three specimens, which seem to 

 agree in this respect, I notice also that the median lobe of the base of the thorax is 

 very narrowly black at the tip ; the tibiae are quite black in two examples, in the third • 

 they are rufous at the tarsal end.
