doubted clavicornis from Senegal, aud, moreover, found the Abyssinian examples 

 were identical therewith, and, further, that the Indian pardalis only differed in 

 certain small points. 



The chief character whereby to separate the two is in the colour of the legs. 

 In pardalis the tibiae and tarsi are wholly black (except the base of the tibise) ; in 

 clavicornis the tibise and tarsi are wholly yellow, or reddish-yellow (the tarsi 

 with black spines). There are some other minor points : — in pardalis the three 

 black spots on the pronotum are usually (but not invariably) connected into a trans- 

 verse line ; in clavicornis they appear to be always widely separated ; in pardalis 

 the transverse black streaks on the anterior-wings are less numerous ; and in clavi- 

 cornis the colour of the body is paler yellow. 



I believe the two may be considered distinct, but it is an interesting point in 

 geographical distribution to find so marked a form existing with only slight modifi- 

 cations from Senegal to India, and also to find that the Abyssinian individuals do 

 not differ from those from Senegal. 



T. clavicornis may be regarded as a resuscitated species, so long had it remained 

 known only by the original indications. — Id. : December \st, 1883. 



Formicaleo tetragrammicus, F., as a Sioiss insect. — According to a remark in 

 Meyer-Diir's " Neuroptern-Fauua der Schweiz " (1875), there exists some doubt as 

 to this Ant-Lion having been observed in Switzerland. I am of opinion that it has 

 liitherto been confused there with Myrmeleon europaus {formicarius, auct.) Dr. 

 Jordan has just sent me an example of F. tetragrammicus that he caught a few years 

 ago near Sierre in the Valais, and I have two specimens labelled " Zermatt." 



I take this opportunity of stating that the " Ascalaphus macaronius, Scop.," of 

 Meyer-Diir, is A. longicornis, L. The two Swiss species are coccajus, W. V., and 

 longicornis, L. The true A. macaronius does not occur so far west in Europe as 

 Switzerland.— Id. : October 30th, 1883. 



Four species of Chrysopa unrecorded for Sioitzerland. — I find in my collection 

 the following species, all taken by myself, that do not appear in Meyer-Diir's 

 " Neuroptern-Fauna :" — Ch. dorsalis,3\irni., a single example beaten from Finns 

 syUestris in the Val d'Anniviers (Valais), 9th July, 1882. Ch. nigricostata, Brauer, 

 Foret de Pfyn and Vispthal (both in the Valais), 10th and 11th July, 1882. Ch. 

 viridana, Schneider, one example on the Alpbach above Meiringen, in July, 1878 ; 

 ordinarily a meridional species. Ch.flava, Scop., Meiringen, July, 1878. In vol. 

 xvii, p. 141, 1 recorded Ch. pallida from Thusis ; in 1882 I saw this species in the 

 late Ed. Pictet's collection at Greneva, with the label " Burgdorf," in Meyer-Diir's 

 hand, so it must have been overlooked by that author when compiling his " Fauna." 



Other unrecorded species of Swiss Planipennia (notably curious forms of 

 Coniopterygidce) are in my collection, but not yet sufficiently worked out. — Id. : 

 December \st, 1883. 



Destrtiction by White Ants at Calcutta. — On a " slip " inserted into Part ii of 

 Vol. li of the " Journal of the Asiatic Society of Bengal " (published August 21st, 

 1882), is printed the following notice : —
