Linearis, castaneo-rufa, nitida, interdum leviter sneo-tincta, longe setosa; thorace cylindrico-angusto (basi 
sulcato-constricto et ante sulcum bituberoso) tuberculo parvo laterali, dorso sparsim setifero-punctato ; 
elytris apice oblique truncatis angulo exteriori obtuse producto, dorso utrinque longitudinaliter depresso, 
subseriatim setifero-punctato, interstitiis punctis nudis minoribus. Antenne articulis 3°-10™ squalibus 
valde dilatatis triangularibus. 
Long. 3-4 lin.

Hemilissa, Pascoe, Trans. Ent. Soc. ser. 2, iv. p. 288; Lacordaire, Gen. Col. viii. p. 327. 
Like Piezocera and Haruspex, from which latter it differs almost solely in the 
acuminated or spinose antenniferous tubercles, confined to Tropical America. Four 
species have been described. 
1. Hemilissa flavicauda. (Tab. XVIII. fig. 7.) 
Quoad formam Haruspict brevipedi simillima. Pavullo minor et gracilior, castaneo-rufa ; elytris apice late flavo- 
testaceis ; sat dense breviter setosa; scapo, capite et thorace opacis asperatis, hoc cylindrico-ovato, basi 
angustato, dorso paullo ineequali, lateribus muticis; elytris apice oblique sinuato-truncatis, angulo exteriori 
paullulum producto, dorso sat confertim confuse (versus apicem obsolete) punctato, punctisque majoribus 
triplici serie; corpore subtus pedibusque sublevibus; tibiis posticis vix compressis carinato-sulcatis. 
Antennis gracilibus, articulo 3° quam ceteri paullulum majori, 3°-10™ carinatis, 6°-9™ leviter serratis. 
Long. 4-5 lin. 
Hab. Guatemaua, Cerro Zunil (Champion). 
COSCINEDES (to follow the genus Hemilissa). 
Subfam. Pirezocerine pertinet, sed tibiis posticis haud carinatis corporeque toto crebre reticulato-punctato. 
Corpus angustum, nudum. Caput exsertum; frons transverso-quadrata lateraliter marginata; tubera 
antennifera lata parum elevata. Palpi brevissimi, articulo apicali anguste triangulari. Antenne (<¢) 
filiformes corpore parum longiores, nude; articulo 3° quam ceteri singuli (et scapus) breviori, 4°
