DESCRIPTIONS OF NEW SPECIES. 227 



The 5th ventral in L. sanguined £ is truncate, but not dentate, 

 in L. Isetifica and quadrillum, it is feebly impressed, but broadly 

 rounded, as in the 9 .

 connexis ; protborace conf'ertiui, antioe subtilius punctato, apice basique 

 constricto, lateribus autice obliquis, dein obtuse angulatis et fere paral-

 tis, apice rotuudatini subtruncatis ; antennis validis ( 9) corporis di- 

 niidio baud longioribus. Loug. 15 rum. 



California; Mr. Ulke. Allied to L. crassipes Lee., but much 

 larger, differing in color, with the antennae very much stouter and 

 shorter.

 giuscula parce vestita ; capite tboraceque subtiliter punctatis, boc lati- 

 tudine longiore, antrorsum angustiore, lateribus subsiuuatis et late ro- 

 tundatis, apice basique transversim constrictis,basi profunde bisinuata, 

 angulis posticis subacutis baud prolongatis ; elytris parallelis, apice 

 subtruncatis, autice planiusculis baud impressis, baud dense punctatis, 



lacula subscutellari, plaga maxima maculam lateralem includente,

One ? ; Mendocino, California, sent by Mr. Jas. Behrens to 

 Dr. Horn. This species is apparently the western analogue of 

 L. 8-notata, but is much larger, and the spots are differently 

 formed and arranged. It gives me much pleasure to dedicate 

 this species to the industrious and intelligent gentleman by whom 

 it was collected, who by his labors has greatly added to our 

 knowledge of the entomological fauna of the Pacific States. 



The antennae are slender, more than half the length of the body, 

 the 4th joint about two-thirds the length of the 5th joint. The 

 spots on the elytra arc; pale yellow ; one near the base, extending 

 obliquely inwards, an oblique fascia running from the margin a 

 little in front of the middle, a second broader fascia behind the 

 middle, connected with the first near the suture, so as to inclose 

 a large sub quadrate lateral spot; another large spot near the tip, 

 attaining neither the suture nor margin. 



Should the yellow spots be greatly extended, and the black re- 

 duced, varieties might occur somewhat resembling some varieties 

 of L. crassipes, but would be at once distinguished by the diffe-
