Society' for August, 1871, and February, 1872, and especially to 

 his two Eeports made to the British Association in 1871 and 1872, 

 on the Structure and Classification of Fossil Crustacea.'* 



A memoir ' Sur les Insectes fossiles du Calcaire lithographique 

 de la Baviere,' by H. Weyenbergh, appears to have escaped the 

 notice of English geologists (published at Harlem, 18G9, imp. 8vo, 

 pp. 48, with four plates). The species belong to the orders Diptera, 

 Neuroptera, Orthoptera, Coleoptera, Hymenoptera, Hemiptera, 

 Homoptera and Lepidoptera (of which last order there is a large 

 Sphinx described under the name of S. Snellii). 



It is an interesting fact that the only species of fossil insect 

 which has been found identical in the " calcaire jurassique " of 

 Bavaria and in the wealden and lias of Great Britain is the Hete- 

 rophlebia dislocata, Westw., although there are many Coleopterous, 

 Dipterous, and especially Orthopterous and Neuropterous genera, 

 which are found in both formations. 



The 'Geological Magazine' has contained a valuable series of 

 papers from time to time on the " Fossil Insect Eemains of 

 England," the first of which appeared in vol. iii., in 1866, con- 

 taining the wing of a new species of dragonfly (Libellula West- 

 woodii) from the Stonesfield slate near Oxford, contributed by 

 Prof. J. Phillips, the veteran geologist. Vol. iv. (1867) contains 

 a paper by Mr. J. W. Kirkby, on the remains of two Orthopterous 

 insects from the coal-measures near Sunderland; and Prof. 

 Dawson, of Montreal, records the remains of five new insects 

 from the Devonian shales, St. John's, New Brunswick (j)l. xvii, 



* In his fourth memoir Mr. Woodward has refigured from my drawing the curious 

 unique fossil specimen in the Hopeian Collection, from Coal brook Dale, which I had 

 likened to the larva of a Saturnia, but which Mr. Salter has redescribed under the 

 name of "Eurjpterus? (Euphoberia) ferox," and as allied to the preceding fossil 

 Crustacea. Another specimen, closely allied to, if not identical with, the same 

 animal has been found in America, and described by Messrs. Meek and Worthen, by 

 •whom it is provisionally referred to the Myriapoda. Supposing it not to have 

 possessed articulated ventral legs, I am not disposed to give up the idea that the 

 animal in question is the larva of some unknown insect, and I am the more 

 confirmed in this opinion by the very interesting discovery of the lai'va of the 

 Neuropterous genus Bittacus by Dr. Brauer, elsewhere alluded to, which possesses 

 several rows of branching spines on each segment; now the Oxford specimen is 

 just what a gigantic Bittacus larva would be, and Bittacus itself is one of those 

 strange forms which seems quite out of place amongst the existing Neuropterous 

 insects. Mr. M'Lachlan, moreover, suggests to me that one of the fossil wings 

 represented from my drawings in Mr. P. Brodie's work is apparently that of a species 

 of Bittacus.
