LIMNOBATINA. 575 



SECTION Z.LIMNOBATINA* 

 FAMILY L LIMNOBATIDJB. 



Genus 1. LIMNOBATES, Burm. 

 Long, very narrow, sublinear. 



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. Antenna very thin, filiform ; 1st joint thickest, shortest, 

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

 the 2nd ; 4th about -J 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 ; 

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

 the 2nd. 



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

 and inesonotum 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 ; coxae progressively longer and more projecting outwardly ; 

 1st pair inserted at the anterior angles of the prosternum, 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
