Derocrania gibbiceps, Chaudoir, Bull. Soc. Moscou, 1860, p. 298. 



Black, with slight metallic reflection, pronotum in front, or 

 altogetlier, rufescent ; head slightly excavate, smooth, with the 

 frontal sulci raised and prolonged beyond the small punctiform 

 impression near the anterior portion of the eyes, sometimes with 

 two impressions between their bases ; pronotum lagenoid, shaped 

 much as in D. nietneri, but with the widened part more parallel- 

 sided and cylindrical, and the collum slightly wider, the upper 

 surface almost smooth ; elytra strongly narrowed in front and 

 much widened and slightly gibbose behind, strongly and deeply 

 punctured throughout except at the extreme apex, the punctures 

 being very close together, but not or scarcely confluent, and being- 

 smaller and more crowded at the base; femora* except apex, red ; 

 tarsi, tibia?, and apex of femora cyaneous. 



Length 12-13 millim. 



Central Ceylon. 



In general shape this species resembles D. nietneri, but it is 

 larger and more widened behind, and may at once be known by 

 the sculpture of the elytra; from B. concinna it may be easily 

 distinguished by the shape of the head and pronotum. 



68. Derocrania flavicornis, W. Born. 



Derocrania jlavicornis, W. Horn, Deutsche Eut. Zeitschr. 1892, 

 p. 92 ; id., Spol. Zeyl. 1904, p. 35, pi. 7, fig. 1. 



According to Dr. Horn this species is intermediate between 

 D. gibbiceps and D. nematodes ; the head and pronotum are as in 

 the former, but the collum of the pronotum is considerably shorter 

 and stouter, the forehead is more excavate, and the longitudinal 

 sulci or plica? are more sharply marked and raised ; in general shape 

 the elytra resemble those of D. nematodes, but they are narrower 

 and more fusiform, and the transverse rugosities are not so 

 distinctly impressed ; the antenna? have the first two joints 

 cyaneous, and the rest, or at least joints 3-6, red or testaceous ; 

 the femora and the tibia?, except the extreme apex, are reddish 

 yellow, the apex and the tarsi being more or less metallic ; elytra 

 terminating externally in two blunt points. 



Length 14-15 millim. 



Ceylon. 



One example of this species exists in Dr. Horn's collection, 

 and one in the Vienna Museum. 



69. Derocrania concinna, Chaud. 



Derocrania concinna, Chaudoir, Bull. Soc. Moscou, 1860, p. 298. 



This species resembles D. nematodes in general appearance, but
