broad and truncate, the intermediate coxae distant; metasternal 

 process truncate, not quite meeting the mesosternum. Tarsal 

 formula 4, 4, 5; the anterior and middle pairs with the first three 

 joints short and subequal, the 4th as long as the tlu'ee preceding 

 together; the posterior pair with the first four joints short and 

 subequal, the 5th as long as the three preceding together. Elytra 

 distinctly sinuate. 



The species on which this genus is founded has the 

 facies of a Gyrophaena, but differs as above indicated by 

 the constricted inner border of the fst joint of the labial 

 palpi, the very strongly toothed inner lobe of the maxilla, 

 and the shorter 1st joint of the posterior tarsi. The genus 

 appears to connect Gyrophaena with Pseudosilusa. 



95. Pseudophaena castanea, n. sp. 



Rufo-castaneous, shining; the elytra strongly punctured; first 

 three joints of the antemiae, mouth-parts and legs reddish-testaceous, 

 the anterior tibiae and apex of intermediate and posterior tibia 

 pitchy. Length 1-8 mm. 



Head large, transverse, the eyes large and moderately prominent ; 

 temples strongly narrowed posteriorly; puncturation very sjjaring 

 and superficial. Antennae with the 1st joint rather stout, longer 

 and stouter than the 2nd, the 3rd a little shorter than the 2nd, 

 the 4th moniliform, the 5th to the 10th transverse, gr-adually 

 increasing in breadth, the penultimate three times as broad as long, 

 tlie 11th short, stout, bluntly pointed. Thorax three-fourths as 

 broad again as long, widest before the middle, the sides rounded 

 and contracted anteriorly, narrowed in a nearly straight line to 

 the obtuse but distinct posterior angles, the sides and base bordered ; 

 the disc with an impressed line in the middle, the base with a trans- 

 verse row of rather large close punctiu'es, the rest of the surface 

 with a few scattered more or less obsolete punctures, sparingly 

 pubescent. Elytra transverse, broader and a little longer than the 

 thorax, for a small species rather coarsely but not closely punctured, 

 sparingly pubescent. Abdomen very finely and very sparingly 

 punctured, the fifth, sixth and seventh segments with coriaceous 

 ground-sculptm-e.
