LONGICORNIA, 237 
Hab. Guarumaa, Cerro Zunil (Champion). 
The punctuation on the broad oblique vitta near the apex of each elytron (most 
conspicuous in the dark brassy examples) is finer and closer than on the rest of the 
surface. A good many specimens were captured.

This interesting and most beautiful species bridges over the slight difference between 
the genera Mallaspis and Pyrodes. It resembles P. marginatus in colour, but differs 
both from that species and from P. tenuicornis in its very much finer sculpture, 
smoother surface, densely pubescent scutellum (at least in the male), and in its shorter, 
smoother, and otherwise coloured antenne. From the male of Pyrodes marginatus it 
is further distinguished by the short, ovate, terminal joints of the antenne, the three 
apical joints in P. marginatus being linear and having (like MZ. moreleti and M. lampros) 
an acute tubercle at their base. Five males and one female. 
Mallaspis rhombodera (p. 10). 
Mr. Champion reports that the apical half of the antenne in this species is quite 
pale in the living insect. 
Mallaspis precellens (p. 11). 
Mr. Champion took this species in great abundance in the forest region of Chiriqui, 
at altitudes of from 800 to 4000 feet. The thorax resembles that of AZ. rhombodera in 
the lateral explanated and serrated margin not commencing until some distance from the 
anterior angle; it is, however, narrower, and further differs from that species in having a 
very prominent and acute tooth just before the posterior angle. It varies in size from 10
