propodeum dull, very densely rugulose in front and with regular 

 transverse wrinkles behind. Abdomen smooth and shining. 

 Length 2-2.5 """n^- 



NOTE. — I have not been able to make dissections of the mouth- 

 parts of this species, but I believe it has five-jointed maxil- 

 lary palpi and does not properly belong to the genus 

 Echthrodelphax. 

 Hab. Bundaberg and Childers, Queensland ; bred. 



. NEODRYINUS gen. nov. 



Head in dorsal aspect strongly transverse, with the vertex 

 more or less concave; in front view, of triangular shape and 

 strongly transverse. Ocelli in an equilateral triangle. Mandibles 

 quadridentate. the apical tooth much the longest, the two inner- 

 most ver}' small, the second distinctly larger than these. Maxil- 

 lary palpi six-jointed, the basal joint very short, the third and fol- 

 lowing joints elongate, the third thicker than the three slender 

 joints that follow; when laid back along the middle line of the 

 head beneath they extend at least more than half its length. 

 Labial palpi three-jointed. Antennae with the five terminal 

 joints somewhat thicker than the preceding ones, so as to be 

 subclavate, the third joint much the longest, much longer than 

 the fourth, and not less than twice as long as the scape. Prono- 

 lum elongate, deeply transversely impressed before the middle, 

 in front conspicuously emarginate, and with the posterior angles 

 not nearly attaining the tegulae. Mesonotum without parapsidal 

 furrows. Postscutellum exceedingly short in the middle. Pro- 

 podeum very long, subequal in length to the mesothorax and 

 scutellum together. Legs much as in Dryiniis Latr. the front 

 pair being much extended, with the trochanters very elongate, 

 many times longer than the intermediate ones, curved and 

 clavate, the stalk long and thin; the fourth joint of the tarsi very 

 long, third moderately long and with a basal lamella beneath, 

 bearing spinose hairs (there are rudiments of these structures on 

 the preceding joint); fifth, seen from above, from its basal articu- 

 lation to the true apex (or point of attachment of the pulvillus) 

 extremely short, subquadrate. but produced beneath basally into 

 a long process, which at rest extends back to the base of the 

 third joint, and is bent and dilated at the tip, the chelar claw 

 greatly developed, about as long as the fifth joint with its basal 

 prolongation, denticulate or spinulose beneath, and with a min- 

 ute tooth near the apex. Front wings with two distinct basal 

 cells and narrow elongate stigma.
