margined, the lobes rounded, the lateral furrows obsolete. 

 Hind femora transversely grooved on upper side only; those 

 of the female with a short apical spine on the inner side. 

 Fore and mid tibiae, below, with four spines in a row ; above 

 the fore tibiae have one anterior spine only, and the mid 

 tibiae have two anterior and two or three posterior spines. 

 Hind tibiae, above, with eight small spines in each row, in ad- 

 dition to the subapical spines ; below there are three small 

 distant spines. The subgenital plate of the male has the 

 apex nearly straight between the insertions of the styles. 



Colours. — Dark-brown or black, with a white spot on each 

 side of the fastigium and a pale-tawny stripe down the centre 

 of the head and back, especially well marked on the prono- 

 tum. A large patch of the same pale colour on the lobes of 

 each of the thoracic nota, and some on the sides of the abdo- 

 men. Tarsi pale-yellowish. Some specimens are nearly all 

 dark-brown.

Onosandrus focalis, sp. nov. Plate XII., figs. b-bd. 



Male : Head smooth, very slightly wrinkled in front ; fas- 

 tigium very broad and flat, the width more than three times 

 that of the first joint of the antennae. Thoracic nota mar- 

 gined, the lobes of the pronotum descending considerably 

 below the others, uniformly rounded. Hind femora sulcate 

 below, the transverse grooves on outer surface obsolete. Fore 

 and mid tibiae, below, with four spines in each row ; above the 

 fore tibia has two spines on the inner side ; the middle tibia 

 has two spines in the outer and four in the inner row. Hind 

 tibiae rounded above, with eight small spines in the inner and 

 six in the outer row, besides the subapical spurs ; below there 

 are a pair of spines just behind the apical spurs, followed by 

 four single spines. The first to the fifth abdominal terga have 

 the anterior half of their lobes roughened, the posterior half 

 smooth. Supra-anal plate triangular, broadly truncated at the 

 apex. Cerci short, curved, erect. Subgenital plate distinctly 

 concave at the apex between the insertions of the styles. 



Coloiirs. — Head black ; a spot on each side of the fastigium, 

 the lower part of the fastigium, the genae, and the clypeus 

 white. Clypeus with two black spots. Upper portion of cly- 

 peus and part of the face grey. Body black above, the front
