SUPPLEMENT. 



(densely), a band across the second and third abdominal segments, and the extreme tip of the abdomen 

 all sulphur-yellow : back of the broad yellow band of the abdomen, and reaching nearly to the tip the 

 hair is rufous, intermixed with black. Elsewhere the body, including the palpi and venter, is clothed with 

 black hair, which is long and dense on the hind tibiae. Wings brown. First two joints of the antenna 

 reddish. Length 20 millim. 



Hal. Mexico, Atoyac in Vera Cruz (H. H Smith). 

 One specimen. 



Mallophora fautrix (p. 191). 



To the locality given, add .-—Mexico, Tepic, Jalisco (Schumann), Atoyac in Vera 

 Cruz (H H. Smith), N. Yucatan (Gaumer). 



Numerous specimens. Most of them agree well with the description, but others 

 show marked differences, which in isolated examples might indicate distinct species. 

 Some of the Yucatan insects have the hair of the scutellum largely, and others almost 

 wholly, black; in several of them, as well as others in which the scutellum is yellow- 

 haired, the hair of the hind tibia- and femora is in part, or almost wholly, white. 



6. Mallophora craverii. 



Mallophora craverii, Bellardi, Saggio etc. ii. p. 22 \ 



Hal. Mexico, Atoyac in Vera Cruz, Teapa in Tabasco (H H Smith), Oaxaca K 

 Two specimens. This species was not identified by Osten Sacken. 



7. Mallophora trapezoidalis. 



Promachus trapezoidalis, Bellardi, Saggio etc. ii. p. 28, t. 2. f. 4 l . 



Hal. Mexico \ Atoyac in Vera Cruz (Schumann, H. H. Smith). 



Twenty-four specimens, varying from 14-20 millim. in length. This species is 

 distinctly Promachus-like in facies, but it has the claws obtuse, as in Mallophora, and 

 the abdomen scarcely longer than the wings. It is apparently allied to M. scopifera, 

 Wiedem. M. trapezoidalis is included by Osten Sacken amongst the unidentified 

 species of Promachus (antea, p. 197). 



8. Mallophora trichostica, sp. n. 



$ . Hair of the beard (which is long and abundant), of the occiput above, and of the palpi and oral margin, 

 yellowish-white; bristles of the face black, somewhat intermixed with white above. Hair of the 

 scutellum black and white. The long and abundant trichostical hairs, a small tuft below them, and some 

 hairs on the front and middle coxae, white. First two segments of the abdomen with black, the remaining 

 segments, both above and below, with yellowish-white hair. Legs black, with black hair. Thorax dark 

 brown. Wings brown. First two joints of the antennas dark red. Length 25 millim. 



J . Very few of the bristles of the face white, and none on the upper part of the occiput. The white 

 trichostical hair less abundant, and absent on the front and middle coxa3. Hair of the abdomen white
