2. Aphanomerus nigcr, sp. nov. 



3. Aphanomerus rufescens, sp. nov. 



4. Aphaiwriierus pusillus, sp. nov. 



These species may be easily separated by the distinctions given 

 in the table below. I may add there is another species ver}- 

 closely allied to A. riifcsccus, represented by a single example, 

 which I have ndt thought it advisable to describe at present. 

 T. (6) Thorax black. 



2. (5) Abdomen largely or entirely ferruginous. 



3. (4) Larger; abdomen wholly ferruginous A. bicolor 



4. (3) Smaller; abdomen dark at least on the apical part. 



A. rufescens. 



5. (2) x\bdomen almost entirely l)lack A. )iigcr 



(\ (t) Thorax yellow or ferruginous 4. pusillus. 



Aphanomerus, gen. nov. 



Moderately or quite robust, the head transverse, and very 

 strongly inflexed, Ithe ocelli very widely separated from one an- 

 other, the anterior one placed very far forwards. Antennae 7- 

 jointed in the female; 8-jointed in the male, the club solid and 

 one-joinited in both sexes. Maxillary palpi two-jointed, labial 

 one-jointed ; mandibles bidentate. Pronotum very little visible 

 in some aspects ; the parapsidal furrows of the mesonotum fine, 

 but evident, and widely separated even at the base ; post scutel- 

 lum more or less prominent in the middle. Legs with uneven 

 claws, the one being much longer than the other. Wings with 

 the submarginal vein terminating in a round knob in the field of 

 the wing, and not reaching the costa, the basal nervure more or 

 less obsolescent, the basal cell incomplete, but its position mark- 

 ed by a darker streak in the position of the median vein. Abdo- 

 men with longitudinal wrinkles or costae at the base. (Plate 

 XT, fig. I. 4 ,5, 6,, 8 and 9.) 



Aphauojiierus bicolor, sp. nov. 



Black, the abdomen ferruginous, the antennae, legs and tegu- 

 lae paler, more testaceous, the club of the antennae in the female 

 largely dark. 



Head and thorax opaque or subopaque, the mesonotum and 

 scutellum with minute microscopic sculpiture and punctuation, 

 so that it appears coriaceous under a lens, clothed with minute 

 !!:;ray pubescence, and with longer gray hairs at the posterior
