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. terebrans, 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 wai'rant 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. pi. 2. fig. 9. 

 {A. reticulata, Dej. Cat. 333; A. Leprieurii, Dej. Cat. 333.) 



A. terebr-anti similis, sed tertia parte minor. Mas? Capite cum 

 fronte sine tuberculis sed fasciculo fulvo piloso instructo ; 

 thorace cylindrico, baud latiore antice, lateribus anticis vix 

 tuberculatis ; elytris subreticulatis, bi- vel tricostatis et apice 

 aciculatim papillosis. Femina ? Capite Isevi, baud 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 Isevibus. 



Long. 8^ lin., lat. 2^ 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. Li 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- 

 cature 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
