toward the final angle of the fourth longitudinal vein ; here it unites 

 with that vein for a very brief distance, then contributes its part to- 

 ward the adventitious oblique vein, until close to the posterior border ; 

 when, at its union with the fifth longitudinal by the posterior trans- 

 verse vein, it suddenly bends outward, and running parallel to and mid- 

 way between the extremity of the fourth longitudinal vein and the pos- 

 terior border, terminates just below the tip of the wing. The third and 

 fifth posterior cells are of nearly equal length.

CoLEOPTERA: 'P AROIj AMI A {rzdpoq, Lamia — nom. gcu.). 



A genus of Ceramhycidw, closely allied to Lamia, but differing from 

 it in the brevity of the head and the structure of the antenn£e. Body 

 heavy, moderately elongated. The head is less than half as long as the 

 prothorax, with less prominent and more nearly approximate antennal 

 tubercles, as compared with Lamia. Antennae moderately slender, half 

 as long again as the body, composed of eleven joints, each cylindrical, 

 scarcely expanded at the distal extremity ; the basal joint is short and 

 stout, its length less than half the width of the head, less than twice 

 as long as broad, tapering apically almost as much as at base ; the sec- 

 ond joint small, of equal diameter with the succeeding, and broader 

 than long; the remaining joints subequal in length, each equal in width 

 until close to its tip, when it expands slightly, the terminal a little 

 shorter than the penultimate. Prothorax transverse, with a not very 

 large spine on either side ; scutellum larger than in Lamia. Tegraina 

 not connate, together more than half as broad again as the base of 

 the pronotum, but with rounded humeral angles, not in the least pro- 

 duced, and with no basal tubercles ; they are nearly parallel in their 

 basal half, but beyond taper regularly, though but slightly, the tip 

 rounded, but not so declivaut exteriorly as in Lamia. Last segment of 

 the abdomen transverse, but longer than in Lamia, broadly and regu- 

 larly rounded, with no excision of the apex. 



This insect is interesting from its belonging to a group not now 

 represented on this continent, the true Lamioides, which are found 

 exclusively in Europe and Africa, and have their home in the Mediter- 

 ranean region. Our nearest allies are the species of Monohammvs. In 

 its form, and the sculpturing. of the surface, it most recalls the genus 

 Lamia proper, but differs from it as well as from the neighboring gen-
