scale is almost trenchant above, not at all transversely impressed, 

 but like that of schistacea and even thinner, and with the outer spines 

 almost as long as the inner. Head as wide as long, very wide behind. 

 Eyes fairly flat, although not so flat as in gagates. Head and thorax 

 sharply and longitudinally rugose ; sides of the head in front reticu- 

 late ; finely reticulate-punctate between the rugae. Femora and 

 tibiae partly reddish to brownish yellow. 



$, 7*5-8 mm. The inner spines of the scale curved somewhat 

 backwards, not much longer than the outer spines and not much 

 further apart from each other than they are from the outer spines. 

 Otherwise like the £.

"In the race gallicola the head is wider and there are some distinct 

 longitudinal rugae, and the thorax, especially the epinotum, is more 

 convex than in this race. The $ is a little more slender than in 

 gallicola, the sculpture finer and the body duller." 



<J>, 7-74 mm. Black, dull, glabrous, except for a very fine and 

 inconspicuous pubescence on the legs and scapes, and a few pilose 

 hairs on the clypeus and apex of abdomen. Head reticulate-punctate, 

 with a few indistinct longitudinal rugae on its anterior half, the 

 clypeus and space between the frontal carinae merely reticulate- 

 punctate, more finely so than on the rest of the head. Thorax and 

 petiole finely and closely reticulate-punctate, the thorax with a few 

 feeble and indistinct longitudinal rugae superimposed. Abdomen 

 densely reticulate-punctate. Head shaped like that of spinicola, the 

 eyes convex and prominent, the clypeus carinate, its anterior margin 

 convex and entire. Pronotum two and a third times wider than long 

 (excluding the neck), armed with a short, wide tooth on each side, 

 shorter than its basal width ; the lateral margins of the pronotum 

 convex. Mesonotum subovate transversely, one-third wider than 

 long, the pro-mesonotal suture arcuate anteriorly, the meso-epinotal 

 arcuate posteriorly. Dorsum of epinotum parallel-sided, a trifle 

 longer than wide, armed with a very small tooth on each side of its 

 apical margin ; declivity nearly as long as the dorsum, concave. 

 Anterior margin of the thorax nearly twice as wide as the apical
