 Termites.— P;'oc. Linn. Soc. N.S.W. 1922, Sydney, xlvii, pt. 2, 

 no. 186, 1922, pp. 142-160, 3 plates, 41 figs. 



The new species dealt with are Eutermes vernoni, the termitaria of 

 which are found in large numbers on the low treeless or nearly treeless 

 country in the vicinity of Townsville ; E. palmerstoni, previously 

 recorded by the author as Eutermes triodiae, Frogg. ; E. mareebensis ; 

 and Hamitermes darwini. H. z&ilsoni, n. n., is proposed for H. 

 perplexus, Hill [R.A.E., A, x, 216], as this name has already been 

 proposed by Banks in 1920 for a species from Texas.

Of the 13 species belonging to the genus here dealt with, two are 

 new and one is a new variety. The larvae are all wood borers and 

 confine their attack to trees belonging to the genus Salix and Populus.

The Saturniid, Coloradia pandora, Blake, is redescribed. This moth 

 is recorded from south Oregon, where the infestation is spreading and 

 great damage is being done to yellow pine {Pinits ponderosa). Trees 

 defoliated in 1919 showed a very sparse crop of short light green needles 

 in 1920. A second defoliation will most probably cause the death of 

 such trees either directl}^ or by facilitating attack by Dendroctonus 

 hrevicomis. 



The eggs of C. pandora are laid over a period of two to three weeks 

 in July. The larvae appear at the end of August ; they are voracious 

 feeders and rapidly defoliate the trees. Adults emerge in late June 

 and early July, the total life-cj'cle probably covering a period of two 

 years. 



The larvae would undoubtedly succumb to any ordinary poison 

 spray, but the expense entailed would only be justifiable on co-operative 

 lines to prevent the further spread of the moth ; it is, however, 

 suggested that the present hmited area of infestation might be cleared 

 at a moderate cost.

In accordance with expectation, brood xiii of Tibicen {Tibicina) 

 septemdecim (periodical cicada) appeared in the Chicago area in 1922. 

 Larvae were first noticed on the 29th April and the first adults emerged 

 on the 28th May. The precision of the appearance of this brood over a 

 period of 70 y^oxs is an interesting instance of the uniformity of 

 development under natural conditions.
