364 SUPPLEMENT. 
The position of Cyrtinus and its allied genera in the Lamiide series of forms is very 
doubtful. Lacordaire placed the group after the ‘Exocentrini” division of the 
“ Acanthocinini,” from which alliance Leconte widely removed them, making them a 
distinct tribe, not far removed from the “ Moneilemini.” The question cannot be satis- 
factorily determined in the absence of connecting forms, graduating in the direction of 
one or other of the great groups of Lamiide, of which they may be eccentric develop- 
ments. The subparallel position of the tarsal claws is mentioned by Leconte in 
speaking of Cyrtinus, but he says the claws appear to be movable, and are sometimes 
divaricate. I have already remarked on the similar variability of position of the claws 
in speaking of Parmena villosa and Penessada fuliginea. 
The Myrmolamiz resemble ants of similar size and colours. They also have a strong 
analogical resemblance to Huderces and Tillomorpha of the family Cerambycide.

2. Myrmolamia penicillata. 
Minor, nigra, undique nitidissima; elytris versus basin fascia angusta, transversa, albo-pubescenti; antennis 
articulis 1°-8™ basi pallidis; elytris basi levibus, tuberculo centro-basali apice longe nigro-penicillato ; 
pedibus nigris vel castaneis, pedunculis pallidis.

LAMIESSA (to precede the group Onciderini, p. 121). 
Forma anomala, gen. Hwmolpo similis. Corpus breviter oblongo-ovatum, longissime erecte pilosum. Caput 
valde retractum, inter antennas latum planum, tubera antennifera nullomodo elevata ; frons quadrata ; oculi 
subtiliter granulati, lobo inferiori sat angusto. Antenne 9-articulate, corpore haud longiores, filiformes, 
undique sparsim setose ; scapo sicut in Hstolis typicis, brevi, sed gracilius clavato, articulo 3° quam scapus 
dimidio longiori, 4° quam precedens paullo breviori et crassiori, 5°-9" multo brevioribus. Thorax 
cylindricus, medio perparum dilatatus, inermis, dorso anteriori valde convexo. Elytra ovata, convexa, 
apice rotundata. Prosternum angustum, inter coxas exsertas depressum, acetabulis extus angulatis; 
mesosternum fere planum; cox posteriores distantes. Pedes mediocres, longe pilosi; tibie sat latee, 
intermediz extus simplices; ungues divaricati, basi lati. 
Unlike any other genus of Lamiide known to me. 
In its structural characters it comes somewhat near to the Pogonocheri and Eupo- 
gonw; but in the thorax and head it most resembles certain genera belonging to the 
true “Saperdini.” It is therefore probably an aberrant form of Saperda, remarkable 
for its relatively short and broad elytra.
