outward and upward and slightly recurved. Scutellum remotely 

 punctate, at apex with an upright spine, which is considerably 

 longer than the pronotal spines. Corium seriately punctate, its 

 inner apical area membranous, the narrow, produced, outer 

 apical part reaching but little beyond middle of membrane, the 

 latter with very distinct veins arising from a basal vein, which 

 is almost contiguous to the apical margin of the corium. Pleura 

 very sparingly punctured, except the thickly and coarsely punc- 

 tate posterior half of the propleura. Abdomen oblong-oval, 

 but with the first two segments narrower and subparallel, venter 

 with an extremely short, dusty, pale pubescence. Legs slender, 

 hind femora a little surpassing apex of abdomen. 



Length, male, 14 millimeters.

In some characters this species is intermediate between M. 

 generosus Stal and quinquespinus Stal, but is very distinct from 

 both, and by the less-produced apical part of the corium it forms 

 a transition to the genus Dulichius. It much resembles a big 

 ant and this resemblance is probably still more striking in the 

 living insect. When a monograph of this group is undertaken 

 a new genus will possibly be required for this species and another 

 for M. quinquespinus, as they differ in several important points 

 from the type of the genus as well as inter se.

Astacops caviceps sp. nov. 



Fulvous; clypeus (at least at apex), a broad median vitta to 

 vertex (posteriorly scarcely reaching beyond the ocelli and some- 

 times entirely wanting) , posterior lobe of pronotum, and corium 

 (including clavus) black, with a slight greenish luster; mem- 

 brane fuscous, antennae black, base of first joint fulvous, ros- 

 trum piceous, legs testaceous, the hind pair (or at least its 

 tibiae and tarsi) more or less infuscated. Head a little broader 

 than humeral width of pronotum, vertex with a longitudinal 

 median groove as broad as the space between the ocelli, ocular 

 peduncles directed outward and slightly upward and backward, 

 ocelli a little more distant from the eyes than from each other, 

 second and third antennal joints subequal in length, fourth one- 

 third longer than third, rostrum reaching or a little passing 

 hind coxae. Pronotum declivous, a little narrowed from the base 

 to apex, the transverse impression well marked, lateral margins 

 a little sinuate, anterior lobe with two strongly divergent levigate
