16 SJOSTEDTS KILI8IANDJARO-MERU EXPEDITION. 13: 2. 



Abdomen black, with very spare, short, erected, whitish hairs. The tips of the 

 segments are very narrowly yellowish. Also the appendices superiores and the border 

 of the genitalvalve of the male. 



Wings hyaline, equal in form, narrow, lanceolate, with the acute tips a little curved. 

 The nervature yellow, blackbrown punctated and the crossveins all narrowly bordered 

 with brown in the forewings, and the apical border of the hindwings densely spotted 

 with brown. Pterostigma yellowish white, very small, only visible on a dark hindground, 

 the proximal part of it with a brown spot. 



Length of body 25 mm., forewings 21 22 mm., hindwings 21 22 mm. Ant. 4 mm. 

 abdomen 20 mm., gr. br. 5 6 mm., gr. br. 4 4 J /2 mm. 



Two specimens, one <f, the pelotte of which is not developed, and one incomplete 

 specimen, which has the distal half of the abdomen broken off, both from Meru low 

 lands, Ngare na nyuki, January 1906. 



Genus: Myrmecacliirus A. COSTA (1855).

Myrmecaelurus tristis (WALKER). 



WALKER, Cat. Brit. Mus. Neur., p. 373. This well-known african species, men- 

 tioned by Prof. KOLBE, 1. c. p. 18, in the genus Myrmcleon, has also a very large dis- 

 tribution. Its generic position is still uncertain, but it has more relation with Myrmecae- 

 lurus than with Myrmeleon. 



A series of nine specimens from the following localities: 



Mem low lands, 22 November 1905, one $. 

 1 December 1905, three a 71 . 

 1 January 1906, one $. 



Kilimandjaro, Kibonoto, cultivated zone, 3 May 1906, one $. - Usambara, 

 Mombo, June 1906, one tf arj d two $. 



The last mentioned specimens are relatively a little smaller than the others. 

 Probably a season form? 



Myrmecaelurus yariegatus (KLUG). 



KLUG, Symb. Phys., tab. 35, fig. 4, tf (1834). - Myrmeleon mysteriosus GER- 

 STAECKER, Mitt, naturw. Ver. Neu-Vorpomm. und Riigen, 25, p. 141, $ (1893). - - KOLBE, 

 1. c. p. 19, laf. fig. 8 (1897). 



I regard this species, with KOLBE, as a representant of a new genus, but its relation 

 is nearer to Myrmecaelurus than to Myrmcleon. KLUG'S type is a male and that of GER- 

 STAECKER a female, but they belong surely to the same species that occurs in Arabia, 

 Eastern Africa and the adjacent Islands, Madagascar etc. 



In this collection is a somewhat immature $ labelled: Meru low lands, 1 Dec. 1905.
