282 Mr. D. Sharp's Contributions to the 



Abdomen immarglnatum, stylls duobus rigidis termi- 

 natum. 



Genus perdistinctum, habitu Pinophilinorum, a quibns 

 ])alporum niaxillarium articulo 4" condito, et prothorace 

 post coxas membranaceo difFcrt. 



Labrum transverse, with the horny part excessively 

 short, and with two stout triangular teeth in the middle ; 

 fi-oni the outside of the teeth proceeds a white membrane, 

 which extends all round the exposed part of the labrum, 

 and much increases its size. Mandibles very slender, long, 

 pointed and curved, and without any trace of teeth. 

 First joint of maxillary palpi much shorter than the others, 

 longer than broad ; 2nd joint rather slender, more than 

 twice as long as the 1st joint ; 3rd joint longer than 2nd, 

 much dilated, especially on the inner side, the extremity 

 rather truncate ; 4th joint quite invisible. Ligula broad 

 in front and emarginate, so as to be in fact bilobed ; para- 

 glossffi ver}^ distinct and greatly developed, extending a 

 good deal beyond the ligula, and distinctly beyond the 

 base of the 2nd joint of labial palpi. First joint of labial 

 palpi concealed in my preparation by the ligula and para- 

 glossa? ; 2nd joint cylindrical, quite twice as long as broad ; 

 3rd joint not much more than half as broad as 2nd, about 

 twice as long as broad. Antennae rather stout, not 

 thickened towards the extremity. Head short and trans- 

 verse, with a moderately broad neck. Thorax transversely 

 quadrate, with the base rounded, the side pieces broad 

 throughout, and Avith a long projection near the hinder 

 part ; membranous under the coxfe ; the coxal cavities thus 

 foi-ming two rather long oblique openings, which are con- 

 fluent in their hinder part. Mesosternum forming chiefly 

 a horny neck, only forming at the base of the middle 

 coxffi a short angular projection. Middle coxal canities 

 large and deep, confluent. Hind body subcylindrical, only 

 the basal segment margined, terminated in two stout, 

 pointed, }-igid styles. AVings present. Front tarsi with 

 the four basal joints forming a broad patella ; 5th joint 

 slender and rather long. Legs moderately long and 

 slender; 1st joint of hind tarsi a little longer than 2nd, 

 4th not at all lobed. 



The curious insect for Avhich I have established this 

 genus has the hind body formed almost as in (Edichirus, 

 and gives one, from its fncies, the idea of a member of the 

 Fi7ioj)hilini rather than i\\Q Pa' derini; nevertheless its syste-
