Classification of I he Coleopterous family Endomi/chidae. 19 



elytral margins well-marked but not wide and the curva- 

 ture of the sides of the prothorax and elytra continuous. 

 The yellow dorsal patches are very large, as in E. felix, 

 the anterior and posterior ones separated by an interval 

 less than the diameter of either, and also less than the 

 interval separating the former from the basal margin. 

 The front tibia of the male has a carina upon its outer 

 edge, as in E. fryanus (but rather less angulated than in 

 that species), and the internal tooth is very strong and 

 arises in the middle. The curvature of the middle and 

 hind tibiae in the same sex is regular and not abrupt. 

 The posterior angles of the prothorax are acute in both 

 sexes and very long in the male, and the extremities of the 

 elytra are produced in the female,

This is another species closely related to, and inter- 

 mediate between, E.fryayius and E. macrospilotus. It is of 

 the same size as the former, and has the margins of the 

 elytra similarly dilated in the corresponding sex. The 

 elytra are a httle shorter relatively, with their margins not 

 wider at the tips than at the sides. The yellow spots are 

 a httle larger than those of E. fryanus, and larger abso- 

 lutely than those of E. macrospilotus, but the latter being 

 a rather smaller insect, the intervals between them are 

 greater. The anterior spots are also placed nearer the 

 base than in the latter insect. The hind angles of the 

 prothorax and the tibiae of the male are as in E. fryanvs, 

 but the last dorsal segment in that sex is less conspicuously 

 bifid at the extremitv.
