blackish band is as wide as the orbits. Antennae and palps black ; 

 autennal chaeta brownish red in the centre, the ciliae short, about 

 equal to the thickening of the chaeta at the base. Abdomen light 

 ashy ; 1st segment black, the others with 3 series of long triangular 

 black spots ; on the venter is a row of large rectangular spots on each 

 side of the median line. Legs black ; wings hyaline ; squamae 

 whitish. 



The 9 resembles completely the same sex of H. sirjnata ; in both 

 the thorax and the scutellum are light ashy grey, on the first are 3 

 dark bands the median of which is continued on the second ; the hairs 

 on the eyes are short ; the abdomen bears the same spots as in the $ , 

 but they are less developed, and the spots on the venter are always in 

 the shape of an elongated triangle. In H. signata 9 the frons is 

 broad and moderately convex ; the orbits are of the same width as the 

 frontal band. 



A $ received from the Belgium Congo differs by the frontal bands 

 diverging backwards ; the antennal chaeta thickened as far as the centre 

 and simply pubescent. The thorax is light ashy grey with 3 dark 

 lines, the 2 lateral of which are indistinct as in H. grisea ? . The 

 scutellum is also light ashy, but the abdomen is similar to that of H. 

 grisea $ . This example may be abnormal ; the frontal lunule is set 

 very deeply in the frons, and there is pair of weak ocellary setae. 



HOPLOCEPHALINA, n. sub-gen. 



I find it necessary to make a new section in the genus 

 for a species having, as in Hoploceplialella, frontal setae complete and 

 directed in the same manner, and the abdomen marked in both sexes 

 with 3 rows of black triangular spots. In Hoplocephalina there is a 

 total absence of acrostical setae on the thorax, except for a weak pair in 

 front of the scutellum ; the hairiness of the genae is crossed by an 

 oblique row of setae, short on the upper part but increasing in length 

 on the lower, and reaching almost that of the frontal setae. Eyes 

 villose ; frons wide, without ocellary setae in the , but with a well- 

 developed pair in the 9 ; frontal band of about the same width in both 

 sexes, a little narrower than the orbits in the 3 , twice narrower in 

 the 9. 



HOPLOCEPHALINA MACULOSA, u. sp. 



Ashy grey in both sexes ; the abdomen, as usual, is depressed in the
