 posed ; disk indefinitely impressed along the suture toward base. Abdomen 

 long, very much longer than the anterior parts, slightly narrower than the 

 elytra ; sides straight and parallel ; border thick ; dorsal plates scarcely twice 

 as wide as long. Length 2.3 mm. ; width 0.5 mm.

The large opaque prothorax, about as wide before the middle as 

 the elytra, and long testaceous abdomen with subapical cloud, will 

 render the identification of this species at all times easy. It is 

 probable that ferrvginea will be regarded as forming a subgenus 

 of Phloeopora, and I therefore give below some of its more im- 

 portant structural characters: — 



Body linear, thick and convex. Head parallel at the sides, 

 rounded and constricted behind, not deeply inserted, the neck not 

 quite two-thirds as wide as the head ; eyes moderate, before the 

 middle ; infralateral carina obsolete. Antennae short, slender, very 

 feebly incrassate, the second joint about as long as the next two; 

 third obconical, twice as long as wide ; outer joints strongly trans- 

 verse, not very densely pubescent and with intermixed short stiff 

 setse ; eleventh small, compressed, conoidal, as long as the two pre- 

 ceding. Mentum moderate, transverse, trapezoidal. Maxillary palpi 

 normal. Ligula with a cylindrical process, which is extremely 

 minutely cleft at apex. Pronotal hypomera feebly inflexed and 

 distinct viewed laterally, narrowed but not obsolete near apex and 

 thence widening and distinct along the oblique apical parts to the 

 neck. Abdomen with the first four segments equally and rather 

 strongly impressed at base ; fifth very slightly longer than the 

 fourth. Intermediate coxae very narrowly separated. Metaster- 

 num ample, the episterna moderate, parallel ; epimera nearly as 

 wide behind as the episterna, disappearing under the elytra at the 

 middle. Legs rather short, femora noticeably stout; tibiae slender; 

 tarsi 5-5-5-jointed, the posterior very slender, three-fourths as long 

 as the tibiae, with the first joint as long as the next two, the fifth as 

 long as the first two together.
