 Frisopus, considered especially in reference to the supposed aqua- 

 tic habits of the genus. In: Entomologist., Bd. XLV, Heft 2, S. 49 — 55, 

 2Textfig., 1912. 



Prisopus fisJieri, n. sp., from the Amazon valley, is described and figured. 

 The species of Prisopus have been stated to have aquatie habits, spending the 

 day attached to stones submerged in streams, and emerging into the air at night. 

 They are of remarkable form, having the underside of the body curiously hollo- 

 wed, and they have been thought to be specially adapted for resting attached to 

 stones under water. An allied Phasmid, Cotylosowa dipneusticum, was considered 

 by Wood-Mason to be also aquatie. Prisopus fisheri was, however, found resting 

 by day on land, on the bark of a tree-trunk. The author discusses the question 

 fully: he concludes that neither Prisopus nor Cotylosoma are in any way aquatie, 

 and that the Statements of their resting submerged under water were founded 

 on insufficient and erroneous evidence. On the other hand they are specially 

 adapted to resting on trees by their protective resemblance to bark, a resem- 

 blance which is added to by some of those very characters previously supposed 

 to fit them for an aquatie existence. H. Scott (Cambridge).

Horridolabis paradoxura Zacher ist identisch mit Anisolabis felix Burr. Änisolabifi 

 aethiopica und vicina Burr müssen in die Gattung Gelotolabis Zacher eingereiht werden. 

 Neu sind folgende Arten: Kalocrania semenoffi sp. n. Westasien: Transkaspische Provinz, 

 Amu Darja. Die erste Pygidicranide aus paläarctischem Gebiet, ähnlich den malaiischen 

 Arten K. pallidipennis und K. siamensia. Ferner: Kalocrania gratet sp. n. aus Mikindani 

 in D. 0. Afrika, Fsalis haenschi sp. n. aus Archidona in Ecuador, Pyga sauteri sp. n. aus 

 Formosa, Frohibia hildebrandti sp. n. eine neue, sehr gut entwickelte Art aus Madagaskar. 

 Neu ist ferner das Vorkommen von Biirriola reiseri Werner in Griechenland und von Elan- 

 no)i bipartitus Kirby in Formosa sowie von Anisolabella braueri Zacher in Nordafrika.

 (Neuropt., Hemerob.). In: Trans. Linn. Soc. London, Bd. XI, Heft 10, S. 151 bis 

 160, PL 32, 1911. 



The author describes in detail the life-history of this interesting Nemopterid. 

 Croce filipennis is found in Bengal, Central India etc. The imago flies for about 

 14 days in April: it is found in the rooms of buildings, and flies chiefly at dusk, 

 several individuals sometimes soaring up and down together after the manner 

 of the Ephemeridae. The life-cycle occupies about H^j^ months. Females in cap- 

 tivity laid 13 — 40 eggs. The eggs are laid singly in dust on the floors of disused 

 rooms. The young larvae emerge after 10 — 12 days, and are about 1,5 mm long, 

 while the full-grown larva is about 7 mm long. Between the head and the trunk- 

 region the larva has a narrow 2-segmented neck. The larva lives among dust, 

 sand etc. on the floors of disused buildings; it Covers itself with a coating of 

 dust; it is entirely carnivorous, feeding by suction with its maxillae and grooved 

 mandibles. Larvae were reared in captivity on Psocids and young Derniestes- 

 larvae. In March the larva spins a nearly spherical cocoou composed of particles 

 of dust bound together by silk. In this the insect spends about 3 weeks. The
