and placed provisionally by him under the genus Lipeurus. Bur- 

 meister placed it under Nirmiis and Giebel followed his example ; thus 

 it remained for Piaget to create a new genus for it, and other species of 

 the same type described by him. This he did in his Les Pediculines. 

 Of the genus, he says: " Since there has been added to the unique 

 species described by Giebel three and probably four new species of 

 the same type, I do not hesitate to establish for them the genus 

 Akidoproctiis, of which the distinctive characters are : The indentation 

 of the clypeus, the existence of a second internal band on the abdo- 

 men and the conical form of the last two abdominal segments." 



Akidoproctus kelloggi, sp. nov. (PI. XXII, Figs, i, 2.) 



Male. — Body, length 3.5 mm., width .8 mm ; whole body pale testaceous with 

 black and varying shades of brown markings on head, thorax and abdomen. 



Head, length .76 mm., width .64 mm.; elongate cordate, rather broadly rounded 

 in front with six short bristles on each side between the trabecule and the clypeal 

 notch ; one .short bristle on each side just within the opening of the notch ; temples 

 with one weak hair and five short bristles ; occiput deeply concave, slightly sinuated 

 and naked ; eye prominent, convex, colorless, and, contrary to Piaget's generic 

 characterization, has a large stiff bristle upon the dorsal surface ; antennae with the 

 second segment longest, each segment semi-annulated with darker testaceous ; a 

 dusky spot on each side of the clypeal notch ; a heavy reddish-brown band across the 

 dorsal surface, joining the trabeculae and pa.ssing over the mandibles ; a blackish 

 ocular blotch and another of the same color at the base of the antennae on top of 

 the brown transverse band ; occipital bands heavy at base and blackish, narrowing 

 and fading to the base of the mandibles ; a pale, somewhat crescent shaped clypeal 

 signature. 



Prothorax short, quadrilateral, with rounded angles, and convex sides ; anterior 

 angles with a blackish-brown, submarginal blotch joining the base of the occipital 

 bands ; a lateral submarginal band of the same color, passing around on the poste- 

 rior borders for a short distance where it is joined by the lateral metathoracic 

 band ; the brown coxal bands showing through very plainly. The metathorax longer 

 than prothorax and nearly twice as wide ; sides rounded and widely diverging ; pos- 

 terior margin sharply angulated with a few weak bristles ; a pair of long hairs at 

 the middle on each side and three at the posterior angles ; heavy black lateral bands 

 separated from the black lateral abdominal bands by a clear space ; the brown coxal 

 lines showing through very plainly. 



Legs short, rather slender, concolorous with body and with blackish tarsi and 

 tips of tibise. 



Abdomen elongate-oval, constricted posteriorly and widest at the second segment ; 

 lateral margins of each segment convex, more so posteriorly ; heavy black lateral 

 bands widely broken by clear sutures ; posterior angles scarcely projecting, with two 

 or three short hairs; a longitudinal, clear, submarginal band parallel to the black 

 lateral bands; remainder of abdomen pale fulvous; segments one to seven with a
