HEPTODONTA,

93. Heptodonta nodicollis, Bates. 



Pronyssa nodicollis, Bates, Ent. Monthly Mag. x, 1874, p. 267. 



A bright, shiny, golden green, elongate and graceful species ; 

 head large, longer than the pronotum ; labrum very long, covering 



the mandibles except the apices, 

 with five distinct teeth and traces 

 (sometimes obsolete) of two others 

 at the sides, green with broad 

 testaceous margins in the male, 

 entirely green in the female (this 

 may be a variable character) ; 

 antennae fuscous with the base 

 metallic, palpi testaceous with the 

 apex dark ; the space between 

 the eyes is concave and the whole 

 head is very finely and closely 

 striate ; pronotum subglobose, 

 transverse, triangularly com- 

 pressed in front and behind, the 

 impressions being aeneous, upper 

 surface finely rugose transversely ; 

 elytra with the shoulders well 

 marked and with a furrow on each 

 side internally, the space between

apex is depressed but not so 

 strongly as in H. pulcliella ; the sides are parallel until a little 

 before the apex and are then obliquely truncate, the apex is trun- 

 cate, and the internal angle ends in a small tooth ; on each there 

 are three white spots close to, but not touching the margin, one 

 at the shoulder, distinct in the male, obsolete in the female, one 

 just about the middle, and one, more or less irregular, before the 

 apex ; the sculpture consists of irregular rugose striae, w T hich are 

 well marked throughout, and the interstices are raised and shiny, 

 giving the insect a frosted appearance when fresh ; legs red, with 

 the knees and part of the anterior femora pitchy ; in the male 

 the first three joints of the anterior and intermediate tarsi are 

 dilated and pilose ; underside bright green with golden reflections. 

 Length 13-15 millim.

Horn (D. E. Z. 1892, p. 94) proposed to place this species in a 

 new genus Tetreurytarsa, but has since placed it under Heptodonta ; 

 there can be no doubt but that it belongs to the latter genus and 

 that it cannot be separated from it.
