In Plate iv. , Fig. 37, of Clapareile's Revlierches sur I'Emlulion dea 

 Arair/ne'es, are represented the rudiments of six pairs of abdominal 

 limbs, three pairs of which are deciduous; the three remaining pairs 

 apparently forming tlie spinnerets. It should be noticed that in Fig. 

 33, only four pairs of abdominal limbs' are shown-. The two other 

 pairs, together with the segments to which they are attached, are 

 developed in the region between the post-abdomen, or terminal lobe, 

 and the basal portion of the abdomen. 



On a Wingless White Ant from Japan. By Dr. H. Hagen. 



1 beg to lay before the Section a new orthopterous insect, belong- 

 ing to the flimily of Termitina, from the alcoholic collection of the 

 Museum of Comparative Zoology at Cambridge. I found only one 

 specimen in a bottle with other insects from Japan. They were col- 

 lected by Mr. Guliek. 



Its very strange form reminded me at 

 first of a Coleopterous larva, or an abnormal 

 Forfjcula, but I was much more interested 

 in finding that the animal belonged to the 

 Termitina. As yet no species has been 

 desciibed from Japan; nevertheless, the 

 occurrence there was proved a long time 

 ago by Kempfer and others. After a closer 

 examination, I find that the species is the 

 very strangest Termes yet known. 



The animal, named by me Hodotermes 

 Japonicus, belongs probably to a new genus, 

 but having only one specimen, it is prudent 

 to jiostpone the creation of a new genus. 

 Iloi/otrrmes Japonicus is nearly fifteen milli- 

 metres long, above flat, pohshed, black, be- 

 neath brown. lis form is of equal lireadth, 

 three to three and one-half millimetres. 

 The abdomen above has very small and 

 sparsely scattered, flat, golden hairs. The 



antennaj have twenty-four articulations, the first and third joint 

 longer and cylindrical; palpi as in Tcrmes; ocelli none; prothorax 

 flat, (piadrangular; mesothorax tranversely oblong with its hinder 

 bordi.T straight, with no traces of a Aving-case. Metathorax similar 

 to the mesothorax, but the hinder border broadly excised. Abdomen 

 very long, with corneous flat segments, the ninth a little shorter. The 

 apex is broad, but is damaged in the specimen. The venter has 

 eight segments, the last large, ovoid, as in the female Termes. The 

 appendices are very short, conic, bi-articulated or broken. The form
