LONGICORNIA. 363 
1. Eurycallinus mirabilis. (Tab. XXII. fig. 22.) 
Ochraceo-fuscus incumbenti-pubescens, elytris linea obliqua utrinque ab humero fere usque ad suturam, fascia 
angusta recta pone medium lituraque flexuosa utrinque prope apicem, ochraceo-albo tomentosis ; capite 
thoraceque impunctatis ; elytris profunde striato-punctatis, versus apicem punctis confusis. 
Long. 38-43 lin. g 9. 
Hab. Mexico, Cordova (Sailé), Jalapa (Hoge). 
There is little or no sexual difference in the anterior tarsi, and very little in the 
length of the antenne. 
Group CYRTININI (to follow the Group Phacellini). 
OMOSAROTES. 
Omosarotes, Pascoe, Journ. of Entom. i. p. 131; Bates, Ann. & Mag. N. H. ser. 3, xvii. p. 194; 
Lacordaire, Gen. Col. ix. p. 820. 
The unique species on which this remarkable genus is founded has hitherto been 
met with only in the Amazons region. 
1. Omosarotes singularis. 
Omosarotes singularis, Pascoe, 1. c. t. 8. f. 5. 
Hab. Panama, Divala (Champion). 
One example. 
Agrees closely with examples from the Amazons, with which I have compared it. 
MYRMOLAMIA. 
Gen. Cyrtino (Leconte) affinis, differt elytrorum humeris rectangulatis apice obtusis. Corpus minutum, glabrum, 
breviter oblongum, angustum. Caput latum inter antennas planum ; oculi parvi, divisi; palpi apice 
tenuiter acuminati. Antenne filiformes, subtus setis nonnullis valde elongatis; scapo valde elongato, 
gradatim graciliter clavato, arcuato ; articulis 39-11” multo brevioribus, gradatim sed parum decrescentibus. 
Thorax inermis, cylindricus postice angustatus et valde depresso-sulcatus, vel cyathiformis dorso anteriori 
valde convexo. Elytra basi depressa; postice modiocriter convexa, tuberculo valido compresso utrinque 
Femora pedunculata et fortiter clavata ; tibiee intermedi extus sinuate. Ungues sub- 
centrobasali. 
divergentes. 
Separated from the North-American genus Cyrtinus with much hesitation, as it 
agrees with Leconte’s description of that genus (Smithson. Contr. 265, pt. ii. p. 333) 
pretty closely in all respects except the “ elytra with rounded humeri,” the shoulders 
being as rectangular as ¢. g. in Pogonocherus mixtus, Hald. The elytra, however, widen 
a little posteriorly: they are gradually declivous behind, and jointly subacuminate- 
rotundate at the apex; they are not “very convex,” nor can the centro-basal tubercle 
be called “a large acute spine,” which Leconte attributes to Cyrtinus.
