3. Apate degenera. 
A. muricate valde affinis, fere tertia parte minor; elytris minus 
Trugosis et minus reticulatis, apice haud leviter punctato sed 
leviter et evanescenter rugoso. 
Long. 9 lin., lat. 3 lin. 
Very close to A. muricata, of which it has the form, but 
nearly a third smaller, and the reticulations on the elytra not 
nearly so marked; they are not much deeper or more decided 
than in A. ¢erebrans, but they have the character of those of A. 
muricata, It is exceedingly difficult to find any definite cha- 
racter to distinguish it from the latter; but the difference in its 
appearance, coupled with the above-mentioned distinctions, 
seem to warrant its being treated as a distinct species. A minor 
difference is that the apical truncature of the elytra, instead of 
being sparsely dotted with small shallow round punctures, is 
smooth, but marked with faint, evanescent, chiefly longitudinal 
corrugations. 
Only one specimen received. 
4. -Apate monacha, Oliv. Ent. iv. pl. 2. fig. 9. 
(A. reticulata, De}. Cat. 333; A. Leprieurii, Dej. Cat. 333.) 
A. terebranti similis, sed tertia parte minor. Mas? Capite cum 
_ fronte sine tuberculis sed fasciculo fulvo piloso instructo ; 
thorace cylindrico, haud latiore antice, lateribus anticis vix 
tuberculatis; elytris subreticulatis, bi- vel tricostatis et apice 
aciculatim papillosis. Femina? Capite levi, haud fulvo piloso; 
thorace parum latiore antice, lateribus anticis tuberculatis vel 
minute dentatis, dentibus anticis uncinatis; elytris vix costatis, 
potius fortiter punctatis quam reticulatis et apice fere levibus. 
Long. 84 lin., lat. 24 lin. : 
The above two forms are, in my opinion, the different sexes 
of the same species, the specimens which I possess of the 
allied species, A. Francisca, Fab., from Algiers, being of two 
forms, which are distinguished by similar differences, and which 
are also probably male and female. In A. monacha the general 
outline of the one is like that of A. terebrans, and that of the 
other is like A. muricata, but each about a third less than them 
in size. What, in accordance with Lacordaire’s suggestion, I 
assume to be the male has a tuft on the forehead, and the elytra 
are subreticulate and bi- or tricostate ; the hollowed apical trun- 
eature is acicularly papillose: in the other sex the tuft is absent 
and the forehead smooth and bare; the thorax is broader, too, 
and the tubercles or teeth on each side of the front of the thorax 
are more numerous and extend to its anterior margin, and the 
foremost of these is hooked. The small tubercles on the disk
