1 think the female must be taken to be the type of this 

 specits. The male described by Smith appears to be funebris 

 with more developed abdominal fasciae, but 1 do not think 

 that the female belongs to the same species, but to another 

 nuile from the same collection, placed by Smith in the series. 

 This is a more robust insect, with the serration of the inter- 

 mediate femora not reaching the apex, in this point resem- 

 bling atrifrons, from which it diHers in the very slight 

 development of the black lobes of the fore tarsus, iu the 

 more robust form, and iu tBe more broadly rounded seventh 

 dorsal segment. In l)oth sexes the labrura and elypeus are 

 black. The thorax of the male is almost entirely black, but 

 there is a yellow spot on the tegula. The antennse are as in 

 atrifrons, but the hollowing of the apical jomts is more 

 distinct. There are seven spines on the basal joint of the 

 fore tarsus in both sexes.

The male has the serration of the intermediate femora not 

 extending either to the base or apex, the intermediate tibiie 

 flattened broadly at the apex, the ba<al joiut of the inter- 

 mediate tarsus broadly emargiuate at the base beneith, the 

 basal joint of the anterior tarsus with seven spines on the 

 outer margin aud a row of black lobes, a faint longitudinal 

 carina on the third ventral segment, as well as the usual 

 tubercle on the second, the labrum black, the mandibles 

 yellow at the base, and the scape entirely black. Tlie female 

 has the scape more or less yellow beneath and the labrum 

 almost entirely yellow.
