HECALUS APICALIS 



in having the head longer and narrower at apex. In its larval 

 state this insect has a very long and slender abdomen and alto- 

 gether bears a striking resemblance to a miniature alligator. 



295. Hecalus apicalis n. sp. 



Brachypterous female : Long and slender 

 posteriorly ; apple-green with a small black 

 spot on the extreme apex of the head. 

 Length 14 mm. ; of the head 3 mm; width 

 of vertex at base 2 mm. 



Head regularly elliptical, very thin; vertex one 

 and a half times as long as its width at base; feebly 

 convex transversely, a little elevated at apex; lon- 

 gitudinally rugose becoming smooth at base. Front 

 moderatel} 7 convex along its disk, depressed and folia- 

 ceous at the sides before the antennae; clypeus rec- 

 tangular, scarcely longer than broad. Pronotum 

 transverse, very feebly arcuated before, slightly angu- 

 larly emarginate behind. Elytra oval, reaching on to the third abdominal 

 segment, costal margin feebly reflexed; clavus with two distant nearly 

 straight nervures. Last ventral segment feebly arcuated behind with a 

 broad triangular median tooth; oviduct exceeding the pygofers by more than 

 one third its length; the latter triangularly produced at apex dorsally. 



Color dull apple-green slightly tinged with testaceous about the apex 

 of the head at the extreme tip of which there is a blackish spot scarcely 

 visible from above. Eyes, produced apex of the pygofers, and oviduct 

 rufous brown. 



Described from two examples taken at Crescent City and 

 St. Petersburg. At Estero I took two larva? which I refer to 

 this species. They have the head a little narrower anteriorly, 

 and the color moie testaceous with three longitudinal lines on 

 the head, pronotum and scutellum. They have the same black 

 mark at the apex of the head that we find in the adult. 



A single macropterous male taken at Estero I also refer to 

 this species, but with some doubt. The vertex is shorter than 

 described above for the female as is the rule in the allied forms, 

 and the clypeus is proportionately longer. It has the same 

 black spot at the apex of the head but the markings otherwise 

 are quite different. The color is dark green shaded with brown, 

 there are two parallel brown vittse from the apex of the vertex, 

 where they converge a little, to the middle of the scutellum, 

 and on either side of these are two more obscure dusky parallel 

 lines ; the elytra are brownish hyaline with the nervures darker,
