blue spot with iiTegiilar contours on the big abdominal ^^egment 

 which otherwise is yellowish. The scales probably give the 

 living animal a rusty reddish tint. Tibiae whitish, sometimes 

 partly bluish, manubrium slightly bluish, dentes uncoloured. 

 Locality. 2 specimens from Mt. Dulit, 3500 feet. 



4. ACANTHURELLA GLAUCA n. sp. 



Diagnosis. Ant. 1=1 : 0.42. 



Ant. II : III : IY = 1 : 1.25 : 1.31 : 1.93. 

 Abd. Ill: IV = 1 : 7. 

 Manubr : Mucrodens=l : 1.02. 



Antorg. II consisting of six free stabes, Antorg. Ill of two 

 obliquely placed, strong staffs in a plica. Dental spines of 

 about the same size and arranged in a row on the interior side 

 of the segment. 



Agrees otherwise in all more important morphological 

 characters completely with the last mentioned species. 



Length of body 3 mm. 



Coloration. With reference to the colour markings the 

 following variations occur : — 



(1) Main colour yellowish with longitudinal stripes on the 

 sides of mesonotum, all joints of antennae dark, nearly black, 

 genae thinly pigmented in a reticulated pattern, legs lightly 

 blue-pigmented, fork light. 1 specimen from Mt. Murud, 

 6500 feet. 



(2) Not quite so strongly pigmented, otherwise entirely 

 agreeing with (1). 4 specimens from Mt. Murud, 6000 feet. 



(3) Pigmentation very undecided. 4 specimens from Mt. 

 Murud, 6500 feet. On a label attached Dr. Mjoberg calls 

 them "ground podurids." Two of those are nearly greyish 

 whitish with mesonotum straight upstanding or even slightly 

 bent forwards. I do not dare, however to classify them as a 

 separate species. 



PSEUDOSIRA Schott. 



Pseudosira has always occupied a very debated position in 

 the system and some authors have even doubted its "raison 

 d'etre." When creating the genus on a single specimen in 

 1893 I was guided only by the following facts : — 



(1) the animal had a Sira-like shape of the body. 



(2) it had falciform mucrones. 



(3) it was covered with scales.
