six nciv species of Elateridn?. 35 



Head ai-med in front with two acute sjiines, coarsely and sparsoly 

 punctate, antenuai pitchy-black, the three hnsal joints rufous, 

 the three apical joints fiavous. Prothorax nearly twice as long 

 as broad, the anterior angles slightly prominent, obtuse, sides 

 gently rounded to the posterior angles, which are ol)tusc. St-u- 

 tellum transverse, pentagonal, iin]»unct;itc. Elyti-a a trifle more 

 than twice the length of the prothorax, wider at the base than 

 it, roundly narrowed to the apex, where they are emarginate 

 at the sutnral angle and ternuuate in an acute spine. Beneath 

 reddish-yellow, head, anterior portion and base of prosternum, 

 reHexed margins of elytra, and a Avide longitudinal stripe tr.i- 

 versing the entire length of the abdomen, black ; legs yellow. 

 Chiguinda. Eight specimens. 



These specimens are variable in size but offer no difference in 

 colouration; in seven of them the sixth abdoininal segment has 

 the apex somewhat truncate, and is furnished with two large 

 elongate-ovate thickly punctate and sparsely pilose foveaj, sepa- 

 rated at their basal four-fifths by an acute ridge, but confluent 

 at the apex; in the eighth specinien the sixth abdominal segment 

 is produced at the apex and is destitute of fovea?. 



Although differing widely in colouration this pretty species 

 is evidently allied to ^S'. znnatns and c/irjitaleniix, and Avill, at 

 present, be best ])laced after the latter, although not in accor- 

 dance with the scheme of arrangement adopted by Candeze. 



4. Eudactuhis pj-odigiis, n. sp. PI. T, fig. 3. 



E. e^ongatus, rufo-aurantiacus, glaber, nitidus ; prothorace 

 quadri-punctato; elytris vitta lata suturali mai-ginibusque later- 

 alibus nigris. Long. 21 mm., lat. 5 mm. 



Elongate, reddish-orange, smooth, shining; eyes, antennas 

 (except the three basal joints, which are rufous j, four oljlong 

 spots on the disc of the prothorax, scutellum, a broad sutural 

 stripe and the lateral margins of the elytra, black. Head 

 rounded anteriorly, tiiickly and co.arsely punctvtc, with a deep 

 narrow triangular fovea in front, antenna; with the third joint 

 fully twice as long as the second. Prothorax conspicuously 

 longer than broad, narrowed from base to apex, the sides gently 

 rounded, anterior angles not prominent, deflexed ; posterior 

 angles produced and divergent, acutely ca.i'inated ; sparsely and 

 rather coarsely punctate. Scutellum oblong, with lai-ge scattered
