Dohrniphora. 149 



on seventh abdominal segment is straight, not curved backwards; 

 along the margin of the eighth segment are six processes, and abov© 

 on this segment lie the larval posterior spiracles on two short processes. 

 On the ventral surface tliere are indications of four slight elevations 

 or warts lying two side by side on each side of the segments. The 

 anterior larval spiracles are distinctly seen at the hind margin of 

 prothorax. The anterior spiracular tubes are of medium length, 

 curved, somewhat distant and directed towards each side. The colour 

 is brownish red, the length 4,5 mm. The puparium of Oldenbergi 

 (fig. 56) is quite like that of florea. The puparium of concinna (fig. 57) 

 is of the same shape and outline as the foregoing, but otherwise 

 somewhat different; there are likewise long, conical and haired pro- 

 cesses, and here six somewhat small processes are seen on meso- 

 thorax, and likewise on metathorax, that between the middle and 

 side process on each side being short; on each abdominal segment 

 there are only four processes, two at the middle and one at each side 

 margin, but between each middle and side process there is a quite 

 small, dot-shaped wart; the processes are all at the posterior margin 

 and give the impression of being placed on the posterior corrugation; 

 the last segment has six long process round the margin; on the seventh 

 segment the middle processes are short. The colour is brown or reddish 

 brown, the length 3 — 3,5 mm. If we take the papillæ or processes 

 present in these four species to be homologous with the papillæ in 

 rufipes ("a" by Keilin), what they no doubt are, then there consequently 

 is the difference that while rufipes has eight papillæ on each abdominal 

 segment, we find here only six (but it is of course not impossible, 

 that a detailed examination of the larva would show small sensory 

 organs representing the fourth pair of papillæ). — The facts recorded 

 above about the breeding of several species seem to show, that the larvæ 

 live in decaying matters of various kind, both animal and vegetable; 

 but it is interesting to see, that the larvæ of some species in so far 

 live in another way, as it is known for several African and Indian 

 species, that they are termitophilous (Schmitz, Wien. Ent. Zeitg. 

 XXXIV, 1915, 312). The hibernation (of the European species) 

 seems, according to the dates for the emerging of the imagines, to 

 be passed in the pupal stage, but concinna, the pupa of which was 

 found and developed in August, has perhaps more than one brood 

 in the year. 



The way in which the genus Dohrniphora has been formed needs 

 some words; when Malloch in 1908 (The Glasgow Naturahst I, 24)
