DESCRIPTIONS OP NEW SPECIES. 227 



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

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

 rounded, as in the 9 .

 punctatis fasciis'tribus apiceque nigris, omnibus ad suturam etmargiuein 

 coimexis ; prothorace confertim, antice subtilius punctate, apice basique 

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

 lelis, basi fortiter bisinuato ; elytris ad basin planiusculis fortiter loba- 

 tis, apice rotuudatiui subtruncatis ; antennis validis ( J ) corporis di- 

 midio baud longioribus. Long. 15 mm. 



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

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

 shorter.

 tundatis, apice basique transversim constrictis, basi profunde bisinuata, 

 angulis posticis subacutis baud prolougatis ; elytris parallelis, apice 

 subtruucatis, antice planiusculis baud impressis, baud dense puuctatis, 



lacula subscntellari, plaga maxima maculam lateralem includente,

One 9 ; Mendocino, California, sent by Mr. Jas. Behrens to 

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

 L. S-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 are 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 subquadrate 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-
