patch bordering the scutellum, an irregular oblique vitta before the middle (extending 
‘from the side downwards towards the suture), and a similar one behind the middle 
(slanting from the sides upwards), the two fasciz being connected by a dusky sutural 
stripe. The tubercles of the thorax are very similar to those of the North-American 
D. undata. |

Distenia chrysostigma, Bates, Trans. Ent. Soc. 1872, p. 196. 
Hab. Nicaracua, Chontales (Belt). 
8. Distenia nigrella. 
Nigra eneo tincta, longe setosa; thorace disco utrinque tumido, polito; elytris dimidio basali confertim grosse 
striato-punctatis, dimidio apicali levibus, apice obtuse rotundatis; femoribus incrassatis, inermibus ; 
antennis breviter pubescentibus, filiformibus, subrobustis. 
Long. 5-6 lin. 
Hab. Guatemaua, Zapote (Champion). 
Unicolorous, shining black, slightly bronzed, with rather long, brown, erect pubescence. 
The usual tubercles of the disk of thorax are not distinguishable, those on each side 
the dorsal line being blended in a large smooth elevation, and the elongated central 
one being obsolete; there are a few minute punctures only in the central depression ; 
the lateral tubercles are well developed, conical, and acute. The elytra have more 
than their basal half thickly striate-punctate, the apical portion being quite smooth. 
9, Distenia vittata. 
Elongata, fusco-nigra, nitida, fulvo-pilosa, antennis (scapo excepto), pedibus (genibus exceptis) vittisque duabus 
utrinque elytrorum fulvis; capite mox pone oculos angustato, collo cylindrico; thorace tuberculis dis- 
coidalibus quinque levibus paullulum elevatis, tuberculo laterali conico obtuso; elytris quam thorax 
duplo latioribus, versus apicem vix attenuatis, apice conjunctim rotundatis, supra dimidio basali subse- 
riatim grosse punctatis, apicem versus irregulariter punctulatis; antennis( 2 ) quam corpus paullo brevioribus, 
breviter pubescentibus, scapo gradatim modice incrassato; tibiis anticis apice extus productis; coxis 
anticis valde exsertis ; prosterni processu angustissimo. 
Long. 93 lin. Q. 
Hab. GuatemMaua, Calderas (Champion). 
In form and colours resembling certain Lepturina (e. g. Oxymirus cursor, Acmeops 
longicornis, Kirb.), to which family it makes some slight approach in its exserted anterior 
coxe, which, however, have not the conical form of the Lepturina. The species is 
probably generically different from Distenia; but until both sexes are known it would 
be unsafe to found a genus upon it. The vitte of the elytra are:—one continuous, 
parallel and very near the suture, diverging from it near the scutellum in the direction 
of the shoulders ; and one marginal, interrupted and irregular in width, passing round 
the apex and joining the sutural stripe.
