Caput pone oculos subito valde constrictum. 
Palpi vix dilatati, lablales vix latiores. 
Antennae 11-articuIatae, articulis baud impressis. 
Thorax angulis posticis baud productis. 
Differs from Strangalia in the form of the thorax alone. Our species may be 
arranged into seven groups, as follows : 
A. Thorace postice modice constricto, elytris triangularibus fere glabris, grossius punctatis, 
a. Elytris apice incisis. Sp. t—3. 
b. Elytris divaricatis, fere integris. Sp. 4—5. 
B. Thorace longiusculo, utrinque subconstricto, elytris parallels, truncatis fere glabris. Sp. 6—8. 
C. Thorace globoso, utrinque constricto, elytris parallelis integris. Sp. 9. 
D. Thorace convexo, canaliculate, laleribus subangulato. 
a. Elytris parallelis parum pubescentibus. Sp. 10—11. 
b. Elytris triangularibus truncatis, valde pubescentibus. Sp. 12—14. 
E. Thorace lateribus parum rotundato, elytris elongatis, vix triangularibus. Sp. I.”)—IS.

1. L. CANADENSIS.—Nigra parum pubescens, thorace elongatulo, antrorsum angustato, cribratim punctato, 
elytris dense grosseque punctatis, punctis versus apicem subtilioribus, basi sanguineis. Long. -4.7—-65. 
% antennis elongatis serratis concoloribus. L. tenuicornis, Hald. 64.

Georgia, New York, Canada. 
2. C. ERYTHROPTERA.—Nigra parum pubescens, thorace latitudine non longiore, antrorsum angustato,

Kirby N. Z. 180. 
Leptura cinnamoptera, Hald. 64. 
New York and Missouri Territory. I have never seen a male : the female has 
antenntE like the preceding. Mr. Haldeman changed the name of this species, 
believing Kirby’s to be preoccupied by Germar : but Say’.s Leptura rubrica having 
priority by one year, this necessity is obviated. 
3. L. RUERiCA. Nigra, thorace flavo pubescente, longiusculo, antrorsum angustato, lateribus rotundatis, 
cribroso, elytris sanguineis, minus dense grosse punctatis, subtilius versus apicem, antennis articulis 
6—10 pallidis apice nigris. Long. •45-'6. 
Say J. A. N. S. 3, 418, (1824.) 
Leptura erythroptera, Germ. Ins. Nov. 522, (1825.) 
New York to Georgia. The male has the abdomen sanguineous.
