232 SJOSTEDTS KILIMANDJARO-MERU EXPEDITION. 8: 7. 



Dielis leptotrichins sp. nov., 



Black, with the following parts sulphur-yellow: the sides of the clypeus broadly, the 

 yellow obliquely narrowed below, through the black central mark being broadly dilated 

 laterally at the apex, this part being obliquely narrowed from the top to the bottom on 

 the upper side; labrum, a longish spot near the base of the mandibles in the centre, 

 the apex of the 4- front femora and their tibia? entirely anteriorly, a broad band on the 

 apex of the 2nd and 3rd dorsal segments, occupying almost the apical half of the seg- 

 ments, the black apical part having the central third roundly dilated, the apical half of 

 the -ith, the black basal band with three rounded dilatations in the centre, the apical 

 half of the 5th, the yellow band narrowed laterally, a similar band on the 6th, and 

 minute spots on the sides of the 2nd and 3rd ventral. Wings hyaline, the nervures 

 fuscous, the radial cellule long, broadly rounded at the apex, the radius projecting beyond 

 the apical transverse cubital nervure somewhat more than the length of the latter, which 

 has its lower half obliquely sloped towards the base of the cellule, o 71 . 



Length 7 15 mm. 



Kilimandjaro: Kibonoto, 1300 1900 m. November. - - Mcni low lands: Ngare 

 na nyuki. January. 



Head, thorax, base of abdomen and legs densely covered with longish, woolly, 

 white pubescence, which is longer and denser on the metathorax than elsewhere. The 

 puncturation on the head is weak and sparse; on the mesonotum it is stronger, but not 

 close, especially towards the apex; the scutellum is closely, distinctly punctured to beyond 

 the middle, except in the centre which is smooth, as is also the apex, which is bare. 

 Pleura? and metanotum closely, but not strongly punctured. 



There is a yellow line in the centre of the metanotum at the apex. The back of 

 the abdomen has a violaceous hue. The species (as is the case with the males of many 

 species of Scolia and Elis) varies greatly in size and in colouration, especially as regards 

 the yellow markings. I have given the description of the larger sized specimens; with 

 the smaller examples the pronotum may have a yellow band all round its apex; the 

 scutellums may be yellow, wholly or in part, the quantity of yellow on the legs varies, 

 the wing nervures vary from black to testaceous, and in the smaller specimens the 

 dilatation on the black basal abdominal marks may not be so well marked. The apical 

 abdominal segment and the apex of the penultimate vary from black to rufous. 



There are 14 specimens, large and small, in the collection, so it is probably a 

 common species. What its $ may be I know not. It is not albicollis, collar-is or 

 fasciatella. 



Dielis collaris, FAB. 



Cf. SAUSSURE and SICHEL, Cat. Gen. sp. Scolii., 163. - -A single male from Kili- 

 maniljtiro, Kibonoto, 1300 1900 m., December, may be this species which is protean 

 in its variation. It is 9 mm. long, is densely covered with cinereous pubescence all 

 over, has rufous testaceous bands on the apices of the dorsal abdominal segments, these
