The largest species of the group; colour metallic, bronze or 

 purplish red ; head large, strougly excavate, with the strise behind 



eyes very distinct, and with 

 strong longitudinal sulci, at the 

 base of which there is a large 

 arcuate excavation, as in D. sci- 

 tiscabra ; pronotum elongate, 

 with a distinct collum, thickly 

 and rather strongly trans - 

 verse-striate ; elytra long, sub- 

 parallel-sided, not much nar- 

 rowed in front or widened 

 behind, and not gibbose, in 

 form and sculpture resembling 

 Tricondyla granulifera, Mots., 

 the sculpture, especially in 

 the middle, being very strong, 

 transversely confluent, and 

 rugose, the interstices being 

 raised in irregular transverse 

 ridges ; antennae dark, with 

 the first and second joints and 

 the apex of the third and fourth 

 more or less distinctly red- 

 Fig. 132.— -Derocrania halyi. dish ; femora red or reddish, 



tibiae and tarsi dark, more or 

 less metallic ; elytra terminating externally in two sharp points. 

 Length 20-21 millim. 

 Ceylox. 



There is an old male specimen of a Derocrania, which has been 

 for many years in the Oxford Museum, and which must evidently be 

 referred to this species ; apart from the sculpture, etc., it is chiefly 

 remarkable for its very long legs, a point which Horn does not 

 notice in his description His figure (I. c.) represents a more 

 robust insect, which is probably the female ; the legs are not 

 figured.
