deep black above. There is another species which infests birds, which differs from 

 it by being testaceous, by being less elongated, and by having shorter antennae. It 

 infests the nests of swallows, finches, pigeons, &c., and is the hirundinii of Curtis 

 and Walker, and includes also columbce, Walk., and fringillcB,'Wa.\k. CeratophylUis 

 e^ow^afw*, Curt., beautifully figured in " British Entomology," appears in Mr.Verrall's 

 list as TyplilopsyUa octactenns, Kolen. ; it infests bats. Typhlopsylla hexactenus, 

 Kolen., is apparently the Pulex vespertilionis, Bouche., found on the long-eared bat.

Entedon Amyclas, Walk. — Mr. Richardson has just given me specimens bred 

 from Nepticitla gei, which agree with specimens in my collection named by Mr. 

 Walker as above. Very little appears to be known at present about the hosts of 

 these little gems, although the kindred families are receiving a fair share of 

 attention. — Id. 



Tettix hipunctafus hihernating. — I thought it was a well known fact that Tettix 

 hipunctatiis hibernated and deposited its eggs in the spi'ing. I have always been 

 able to take it all through the winter from rubbish and dead leaves. I have also 

 taken the other species in the winter, but more rarely. — Id. 



The Immatuke State of the Odonata. Part iii : by Louis Cabot. 

 Memoirs of the Museum of Comparative Anatomy at Harvard College, Cambridge, 

 U.S.A., 1890, with six plates : -ito. 



This is a third instalment of a valuable series of memoirs, drawn up with great 

 care, and illustrated from the author's drawings by plates of the highest order of 

 lithography. The present part mainly concerns the sub-family Corduliina, with the 

 addition of Pantala and Tramea in the Libellulina. 



For the Corduliina, the author notices, or describes and figures, twenty-four 

 species. All is done with the greatest care. Many nymphs are given as on sup- 

 position only, others with certainty, and others as undoubtedly uncertain. In our 

 present state of knowledge of the preliminary stages of Dragon-flies, and the indu- 

 bitable difiiculty of rearing them, unless the nymphs be in a very advanced stage, 

 uncertainty, to a greater or lesser extent, is inevitable. The broad principle as to 

 the position of certain " nymphs " may rest undoubted ; but to apply this principle 

 in the manner that would be adopted with tolerable certainty of success by a 

 Lepidopterist would here be futile. Much depends upon conditions, such as the finding 

 of nymph-skins, with the perfect Dragon-flies in the immediate neighbourhood. The 

 field-naturalist has had in view a still more important point. Dragon-flies on 

 emerging from the nymph do not for some considerable time (varying as to the 

 temperature) move far from the skin they have lately shed. And it is due to this 

 that a very large majority of the nymphs (or rather the cast-off skins of them) have 

 been identified with the perfect insects they produced.
