Miscellaneous. iS^l 



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

 (22 millims. long) female insect brought from Pegu by Mr. Kurz, 

 and apparently allied to Hestias and Oxijpihis hicingulata, De Haan, 

 the upper edges of the fore femora are sharply crested, but not 

 so greatly expanded ; the cephalic cone is bicuspid at the ex- 

 tremity, and 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 organs of flight do not nearly reach to the extremity of the 

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

 erect, spiniform tubercles. From the analogy of Hestias, I confi- 

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

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

 inantis tSaussurii. 



I also exhibit the two sexes of an insect captured, the female by 

 Mr, Peal in the Naga 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 obtusely 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 little more than a tubercle 

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

 insect Phi/IIocrania Westwoodi, notwithstanding that the prothorax 

 has no foliaceous expansions. 



Similar sexual differences may be looked for in Pht/Uocrania, 

 Parahlepharis, and Sibylla, the males of which are still unknown. 



In the Phasmidae we meet with apparently similar sexual difi'er- 

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

 of body that has taken place in the males may well have effaced 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 Phi/Uiiim, wherein the foliaceous lobes 

 of the abdomen and legs of the female are relatively very large, and 

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

 in the case of Lonchodes insignis, in which in males more than ordi- 

 narily stout the cephalic horns reappear in rudiment though they 

 have disappeared in slenderer individuals. 



Prof. Wood-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 Mantidiie to keep their eyes and ocelli 

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

 when these quit the Q^^. — Proceedings of the Asiatic Society of

 The Nematode discovered by Dr. Normand in the faeces of patients 

 affected with Cochin-China diarrhoea, and provisionally named by 

 me Anguillala stercoralis, may justly retain that designation; but it
