4 SJÖSTEDTS KILIMANDJARO-MEEU EXPEDITION. 1/:1. 



Gen. Anisolabis Fieber. 



In Lotos, in. p. 257, 1853. 



Anisolabis laeta Gerst. 



In Arch. f. Naturg., XXXV. p. 221 (1869). 



Kilimandjaro: Kibonoto. 31 males, 39 females and 22 larvae. August to No- 

 vember. Some taken under dead Banana leaves. One male from Kibonoto (12. IV. 06) 

 was taken in a nest of Termes goliath Sjöst., with a smaller species of Termes Termes 

 vadschaggae Sjöst. n. sp. on the walls. 



PI. 1, fig. 3. This species was discovered by Dr. Kersten, who took a Single 

 female on November 30th, 1862 at an elevation of 8,000 ft, (about 3,200 m.) on Kili- 

 mandjaro; it was described and figured by Gerstaecker (1. c.) in bis work upon the 

 results of van der Decken's travels in East Africa. Since then it has not been re- 

 corded. A somewhat similar species was taken by Fea in Tenasserim, and recorded by 

 de Bormans as A. laeta, but Kirby has shown this to be quite distinct. 



The male closely resembles the female; it is of the same size (14— 16 mm.), the 

 dimensions given by de Bormans (Tierreich. Forf. p. 46, 1900), (28 mm.) being those 

 of A. dubronii, the totally distinct species from Tenasserim, confused by de Bormans 

 with A. laeta, but separated by Kirby. The forceps of the male hardly differ from 

 those of the female; they are slightly more slender and more curved, the right brauch 

 particularly being more strongly curved at the apex, so that it distinctly overlaps 

 the left brauch; the most notable character is the form of the sides of the dorsal 

 plates of the abdomen; when seen from the side, these plates are convex posteriorly, 

 that is, their posterior border is not vertical but produced into an angle pointing 

 posteriorly and this angle is more acute in the apical segments; each segment is also 

 provided with a small but quite distinct horizontal carina which runs along to the 

 apex of the convex portion. This structure is seen to a ccrtain extent in A. felix n., 

 which is described later. 



Anisolabis annulipes Lucas. 

 Ann. Soc. ent. Fr. ser. 2. v. Bull. 841, 1847. 

 Kilimandjaro: Kibonoto. 1,300-1,900 m. 2 males and 5 females, which all 

 seem to belong to this species; in the ringed feet and antennae, and general appea- 

 rance they agree, but differ in build; they are longer and more slender than any 

 true L. anmdipes that I have examined, and the forceps are more slender and longer; 

 they are perhaps a local race of this universally distributed species. 



Anisolabis felix n. sp.

 Statura majore; colore atro; caput rufum; antennae fusco-testaceae; elytranuUa;
