1906), from fresh and living specimens, and he remarks: "The 

 points which settle the sex to a casual observer, are : 



" 1. The size of the orange spot on the pronotum andscutellum. 

 In the female it is much bigger than in the male, and in fact in 

 the latter it is often hardly to be seen. 



" 2. The shape of the abdomen, which is always larger and 

 stouter in the female. 



" 3. The size of the insect, the female being always distinctly 

 bigger in every respect. 



" 4. The presence of the ovipositor in the female." 



Mr. Mann also states that " the males are always present in 

 much smaller numbers than the females." 



When enumerating the species of the genus I placed the H. feb- 

 riculosa, Bergr. as a probable synonym of H. theivora, Water h. 

 (vol. ii, p. 440). Mr. Mann (Mem. Dept. Agr. Ind. Ent. ser. i, 

 no. 4, p. 331, 1907), writes : " I have shown conclusively that the 

 H. febriculosa as described by Bergroth comes well within the 

 variation noticed for H. iheivora, and that the observations give 

 no indication of the presence of two distinct types under the latter. 

 I should, in fact, be inclined to consider Bergroth's insect as not 

 even a definite variety, but rather as a mere casual and individual 

 variation.*'

Head, pronotum, scutellum, and corium bronzy ochraceous ; 

 head with three longitudinal black lines, the lateral ones con- 

 verging anteriorly ; antennae with the basal joint bronzy ochra- 

 ceous, with a more or less distinct piceous line beneath, second 

 joint black, with its base ochraceous (remaining joints mutilated 

 in typical specimens) ; pronotal collar with the margins and three 

 longitudinal lines black, the central line more prominent, posterior 

 pronotal margin and the posterior angles black ; clavus with the 

 inner and outer margins and the suture black; corium with the 

 costal marginal area paler and bordered on each side with black, 

 veins piceous; membrane pale olivaceous, subhyaline, the ba^al 

 area reflecting the darker abdomen beneath, the cellular margins 

 black; body beneath, rostrum, and legs ochraceous; antenna? with 

 the basal joint moderately thickened and a little longer than head, 

 second joint slightly thickened and nearly four times as long as
