new Species o/" Halticinae. 231 



versely below the basilar space, from the base to beyond the 

 middle faintly depressed longitudinally along the suture, more 

 finely punctured than the thorax, greenish yellow; a large longi- 

 tudinal patch on the disk of each elytron, covering nearly its 

 whole surface, but attenuated at the base, pale green ; each 

 elytron with two narrow piceous lines, commencing at the base 

 and abbreviated below the middle, one placed on the suture 

 and the other on the lateral margin. 



The broad thorax gives this species an entirely different 

 aspect to the typical form of the genus ; but I cannot find any 

 essential structural difference. 



PJiygasia dorsata. 



P. ovata, convexa, nigra, nitida ; elytris fulvis, apice plagaquo 

 magna discoidali communi nigris, utrinque vittis elevatis trib\ia, 

 basi et apice abbreviatis, exteriore pone medium fracta et ramu- 

 lum brevem introrsum emittente, instructis.

Vertex smooth, impunctate ; encarpse subpyriform, contigu- 

 ous ; carina narrow, elongate ; antennse more than two thirds 

 the length of the body, filiform, three or four lower joints 

 piceous, the rest black. Thorax nearly twice as broad as 

 long; sides broadly margined, reflexed, rounded, converging 

 towards the base, the anterior angles produced, thickened, 

 obtuse ; basal groove deeply impressed, terminated on either 

 side by a deep fovea ; disk smooth, impunctate. Elytra 

 oblong-ovate, broader than the thorax, attenuated towards the 

 apex, the latter subacute, slightly recurved ; surface minutely 

 punctured, each elytron with three longitudinal ribs ; of 

 these the outer one commences on the humeral callus, and 

 extends three fourths the length of tlie elytron ; the second 

 commences just below and rather within the humeral callus, 

 and runs parallel to the outer rib, terminating at about the 

 same distance from the apex of the elytron, the third or inner 

 one is placed on the line of junction between the inner and 

 outer disks, and is much shorter than the two others, com- 

 mencing considerably below the base, and terminating at a 

 short distance below the middle ; the outer rib below its 

 middle is more or less distinctly interrupted, sending a short 

 ill-defined ramus towards the intermediate rib ; lastly, parallel 

 to the suture at its apex is a raised longitudinal line : 

 commencing just before the middle of the disk and extending 

 nearly to the black apex is a large common shield-shaped
