62 MR. R. SHELFORD : THE BRITISH MUSEUM 



derelict leg is quite clear and undisturbed, so that the enclosure of the leg in 

 resin was an event ensuing after its entanglement, 



? POLYPHAGA FOSSILIS. 

 Polyphacjafossilis, Shelford, Journ. Linn. Soc, Zool. xxx. (1910) p. 351, pi. 48. fig. 21. 



One very young larva which can only be identified with great uncertainty. 

 The preservation o£ the specimen is not good. No. 1 .13752. 



Larv^. 



Four specimens, Nos. I 13747, 1 13749, 1 13750, I 13753, are probably the 

 very young larvse of a species of Phyllodromia : a fifth example. No. 1 13751, 

 is a youno- larva of one of the Blattse muticae ; the insect is much distorted 

 owing to the extrusion of some of the viscera between the thoracic sclerites ; 

 it is possibly identical with the Polyzosteria parvula of Berendt (Ann. Soc. 

 ent. France, vol. v. p. 542, pi. 16. fig. 1, 1836). 



II. MIOCENE SPECIES FEOM STETTIN. 



The small number of Miocene specimens debars us from drawing any very 

 valuable conclusions from a comparison of the Oligoccne and Miocene 

 Blattidse in amber, but we may note the followdng points : — 



The genera Ectobius, Isclmoptera, Temnojyte^yx, Nyctibora, Holocompsa, and 

 Poh/phaga are not represented in the collection from Stettin ; two genera 

 make their first appearance in the Miocene, Pseudojjhyllodromia and 

 Eutliyrrlmplia ; two genera, Phyllodromia and Ceratinoptera, are common to 

 both horizons^ but the Miocene species of the former genus are very different 

 from the Oligocene species and present, if possible, even a more modern 

 appearance. C/omment has already been passed on the occurrence of the' 

 genus EutliyrrhajDlia in the Miocene fauna. 



These British Museum specimens have the surface of the amber blocks 

 reticulated with minute cracks, so that the examination of the enclosed 

 insects is attended with some difficulty, but I hope that I have succeeded in 

 making out all the details of structure which are visible. 



Phyllodromia woodwardi, sp. n. (Plate 7. fig. 5.) 



One male, No. 58577 ; one female, No. 1 13770. 



Flavo-testaceous ; eyes rufous ; frons with a V-shaped dark macula. 

 Antennse long and slender, apical joints dark. Pronotum transversely 

 elliptical, anteriorly not covering vertex of head, posteriorly very slightly 

 produced, disc immaculate, lateral margins hyaline. Tegmina and wings 

 barely exceeding apex of abdomen. Tegmina immaculate, moderately broad, 

 the discoidal sectors straight. Wino-g with mediastinal vein multiramose
