In tlio next specimen to which I would draw attention, a small 

 ('J'J niillinis. loii";) female insect broui^ht from Pej^u by ^fr. Kurz, 

 and apparently allied to //>:<<( itin .iml O.i-ifpiliis hicinijul'tttt, Do llaan, 

 the npper edj^es of the fore femora are sharplj* crested, hut not 

 80 fi^rcatly expandeil ; the cephalic cone is bicuspid at the ex- 

 tremity, anil armed with two pointed cusps on each side ; the 

 occiput presents behind each eye a pointed tubercle directed back- 

 wards : the face is carinate, the keel of the "facial shield" ter- 

 minating above in a stout conical tooth ; the two upper ocelli 

 are surmounted by a pair of long and slender conical spines ; 

 the org ins of tlight do not nearly reach to th(! extremity of tlu* 

 abdomen ; and the disk of the prothorax is armed with four sharp, 

 erect, spiniforra tubercles. From the analogy of //('.<//'«.<, 1 confi- 

 dently expect that the male will prove to have its head similarly 

 armed with a tubercle. I have named this curious insect Cerato- 

 mantis S(tit.<ssrn'ii. 



I al-^o exhibit the two sexes of an insect captured, the female by 

 ^^r. Peal in the Xaga hills, and the male by Dr. Cameron in the 

 Bhutan Doars. In the former the head is provided with a long and 

 slightly tapering foliaceous frontal horn, truncated at the apex, 

 longitudinally obtuselj- carinate in front, and sharply crested behind, 

 and nearly tliree times as long as the head is high : in the latter 

 this great foliaceous horn is reduced to Ifttle more than a tubercle 

 only about half as long as the head is high. I have named this 

 insect Phifllocranut WcsftrooJi, notwithstanding that the prothorax 

 has no foliaceous expansions. 



Similar sexual ditiercnees may be looked for in P/u/Ilocirtiila, 

 J^trahhpharix, and SSilojUd, the males of which are still unknown. 



In the Phasmidaj we meet with apparently similar sexual differ- 

 ences ; but in these insects the great reduction in size and thickness 

 of body that has taken place in the males may well have efiliced the 

 horns and foliaceous lobes, which after all are generally relatively 

 not very greatly developed in the females. "We see the truth of 

 this in the case of the genus PJi>/Uium, wherein tlie foliaceous lobes 

 of the abdomen and legs of the female are relativ«'ly very large, and 

 those of the male are consequently by no means inappreciable, and 

 in the case of LoitcJunles l)u<lifnh^ in which in males more than ordi- 

 narily stout the cephalic horns reappear in rudiment though they 

 have disappeared in slenderer individuals. 



Prof. AVood-Mason also announced that he had ascertained by actual 

 observation of living specimens belonging to several species that the 

 femoral brushes are used by the Mantidie to keep their eyes and ocelli 

 in a functional condition, and that they are present in the young 

 when these quit the egg. — Procee'liit'js of the Asiatic Societif of
