niul witli a less distinct keel down the middle ; the post- 

 pel inle closely stronjily striated in the middle, the sides 

 almost smooth ; ti»e second to sixth sofrnuMits closely punc- 

 tured, the puncturation becoming <,n;ulually weaker; the 

 second and third striated down the midtlle. Gastrocoeli deep, 

 smooth. 



This species is not unlike A. ru/ocincla, Cam., in colora- 

 tion ; it differs in the scutellum being longer compared with 

 the width, more raised at the base, and with tlie lateral keels 

 longer and more distinct, and the areola is smaller and more 

 narrowed — more sharp-pointed — at the base.

 pleur£e above, the apical half below, the metapleura?, meta- 

 notum, the basal segment of abdomen, and the second to 

 shortly beyond the middle, the mesosternum (except for a 

 triangular space on either side at the base), the hind coxaj, 

 aiid the base of the trochanters above, black. The basal 

 sixteen joints of antennre yellow, tinged with red, the rest

Sikkira. 



Head and thorax somewhat strongly closely punctured ; 

 the eye-orbits are tinged with yellow, the yellow tinge 

 broader on the lower outer orbits. The apex of mesonotum 

 lighter-coloured in the middle. Base of metanotum strongly 

 punctured (except for a smooth space bordering the areola) ; 

 the latter is gradually narrowed from the apex to the base, 

 which is rounded, narrow; the apex is rounded inwardly, 

 the keel narrow, irregular; the outer edge of the inner side 

 is irregularly narrowly depressed ; in the centre is an irregular 

 depression, and there are two smaller ones at the apex; the 

 apical slope is irregularly strongly reticulated, the posterior 

 median area more strongly than the lateral. Abdomen 

 closely ])unctured, strongly at the base, weaker towards the 

 a{»ex ; the second segment depressed at the base, between the 

 gastrocceli, closely striated ; the latter has four stout clearly 

 separated keels on the inner half and one near the outer 

 side.
