jmdicus, and cossyphus^ Mars., and bisinuatus, Sell., have no 

 prosternal striae ; in the other known species the prosternum 

 is bistriate.

Oblong, opaque, black, and densely punctured above ; the 

 head is concave behind the frontal stria, with large irregular 

 punctures, chiefly on the sides of the concavity, the stria is 

 complete and biarcuate ; the thorax, the marginal stria is 

 rather fine and continued behind the head, within the marginal 

 stria there is a narrow border free of punctures, but there is 

 no lateral stria visible except behind the anterior angle ; the 

 elytra are densely and rather rugosely punctured, the six 

 dorsal strife are punctate, complete, but not deeply impressed, 

 the outer humeral is impunctate and slightly deeper but 

 much shortened at both ends, the inner humeral is vague, 

 the sutural and fifth strise apparently join at the base; the 

 propygidium is also densely punctured, but the punctures are 

 large, shallow, and ovate and the surface reticulate between 

 the points ; the pygidium is somewhat similarly sculptured, 

 but the punctures are circular • the prosternum, the anterior 

 lobe has a fine but clear marginal stria and a few large 

 irregular punctures ; the keel is deeply and very roughly 

 sculptured with deep and confluent punctures, the anterior 

 lobe has but few irregular punctures. 



This curious species is somewhat similar to P. opacus^ 

 Lew. ; the latter, however, has no marginal stria in the 

 anterior lobe of the prosternum, which I did not mention in 

 my original description, and in P. Brauni the propygidium 

 is more transverse.

 galleries of Termes tubicola, Westw., by Dr. H. Braun, after 

 whom I have much pleasure in naming it.
