SectioxN I^—LIMNOBATINA!^ 



Family 1.— LlMNOBATIDyE. 



Genus 1. — Limnobates, Barm. 

 Long, very narrow, subliuear. 



Head horizontal, subcylindrical,' as long as the thorax, widened to 

 the front as far as the base of the antennae, the sides thence 

 suddenly convergent, the front subtruncate, produced on each side 

 in a very small point ; Face very short, subquadrate, deflected ; cheek- 

 plates long, projecting in front. Antenniferous processes small, 

 prominent. Antennae very thin, filiform ; 1st joint thickest, shortest, 

 subclavate ; 2nd longer than the 1st ; 3rd nearly 3 times as long as 

 the 2nd ; J;th about \ as long as the 3rd. Eyes large, hemispherical, 

 prominent, but deeply set in the sides of the head rather behind the 

 middle. 'Rostrum subsetaceous, reaching to beyond the eyes j 

 base in a short channel ; 2nd joint long ; 3rd \ the length of 

 the 2nd. 



Tliorax much wider than the head, subcylindrical ; Pronotum (pro- 

 and mesonotum united in 1 plate) long, convex, the pronotal portion 

 rather narrower than the mesonotal, the disk transversely depressed 

 at their junction ; the sides of each part straight, parallel ; down the 

 middle a slight linear channel ; posterior margin broadly rounded. 

 Elytra usually only as long as the metanotum, and posteriorly trun- 

 cate, when developed not quite so long as the abdomen, narrow, 

 linear, with 2 long nerves ; the 1st close and parallel to the anterior 

 margin, except that it touches it about the middle ; the 2nd distant 

 from the inner margin ; both connected by an oblique nerve consi- 

 derably beyond the middle, and another transverse one before the 

 apex, thus forming an irregular cell. Wings narrow, without a fold. 

 Sternum ; coxa progressively longer and more projecting outwardly ; 

 1st pair inserted at the anterior angles of the presternum, vertical ; 

 2nd and 3rd posterior, oblique. Legs long, thin, filiform ; 1st and 

 2nd pairs in length subequal ; 3rd pair longest ; fulcra very thin at 

 the base, turned upwards ; tarsi long, thin, cylindrical, in length
