Ebcroiuorphus, Pic, L'Ecbange, xx. p. 28 (HK)4) [nee A/talm, eubjren. 

 Ebfrimorphiis, Abeille de l*erriii, Auu. Soc. Eut. ¥x. 181X), p. 578 

 (1891)] [type E. ramicornis^ Pic]. 



The Ethiopian insects liere referred to Ebceus difler from 

 their northern allies in the ariuature or shape of the apices 

 of the elytra in the c? ; the appendages when fully deve- 

 loped {E. hicuiidatus) are not like those of the tyje of the 

 genus {E. pediciiUir'ms, Sehraiik), and when absent {E. in- 

 ennipeunis, Pic, &c.) are replaced by a tumid, smooth, or 

 hollow space. In Jidceus, s. sir., cJ , tliere are two appen- 

 dages — a small inner one and a large subtriangular, ear- 

 shaped, or oblong, apical or outer one, the latter retractile 

 and partially closing the terminal cavity. This structure is 

 not to be found in the southern forn)s, nevertheless the 

 name Urodactylus, J. Thorns. (= Mixis, Ab.), cannot be 

 retained for them. Abeille de Perrin attached too nmch 

 importance to the surface-vestiture — wholly fine and seri- 

 ceous in Kbceus, and with intermixed longer hairs or erect 

 setse in Mixis, a character that cannot be regarded as 

 of generic value. The flabellate or pectinate antennae in 

 the J' (7:\ rainlcornis, Boh., apricus, Gorh., &c.) is an un- 

 important secondary sexual character occurring also in 

 Malachius and Hapalochrus. Hbaus therefore, in the wide 

 sense, is separable from Attcdus, Avhich has similar anterior 

 tarsi in ^ , by the appendiculate or peculiarly-formed apices 

 of the elytra in this sex, the head wanting the frontal 

 excavation so conspicuous in the males of llebijlnus, &c. 

 The simple tarsal structure of Antkocomus distinguishes 

 that genus from Attains and Ebceus,
