Dec, i9i9-] Shaeffer: Notes on Chrysomelid^e. 319 



angles distinct and moderately prominent; anterior tubercles distinct; sides 

 feebly undulate ; surface slightly uneven ; median impression absent ; basal 

 impression distinct; surface alutaceous and finely and rather sparsely punctate; 

 punctures more dense at middle and larger at apex and base. Elytra about 

 three times as long as the prothorax and a little more than twice as long as 

 wide at base; punctures of regular series moderate, intervals rather feebly 

 rugose on the disk, more distinctly so at sides and apex ; sutural margin near 

 apex sinuate ; apices separately rounded. Body beneath cupreous ; thinly 

 clothed with short, cinereous pubescence ; posterior femora with a moderate, 

 triangular tooth. Apex of the lower vaginal plate relatively coarsely serrate. 

 Length 7.25 mm. 



Male. — Differs only in being narrower with slightly longer antennal joints ; 

 tooth of posterior femora scarcely larger than in the female. 



The type is from Stephenville, New Foundland, collected by 

 George P. Engelhardt. It is taken in Maine by Mr. C. A. Frost and I 

 have also a specimen from Montana, British Colombia and Wyoming 

 and Mr. Davis has taken a specimen in Lakehurst, N. J. A very dis- 

 tinct species by its form and sculpture of prothorax and the only 

 species known to me which have the lower vaginal plate of the female 

 coarsely serrate at apex. In all the other species the serration is 

 either absent or very fine. 



Zeugophora neomexicana new species. 



Black ; head, prothorax and legs reddish-yellow ; outer joints of antennae 

 piceous or black. Head moderately densely punctate. Prothorax more sparsely 

 punctate than the head ; lateral tubercle moderately prominent, lateral margin 

 above the tubercle straight, not obliquely narrowing to the apical angles. 

 Elytra sparsely pubescent ; punctures larger than those on the pronotum, well 

 separated on the disk, closer at sides. Length 3 mm. 



Santa Fe, New Mexico. 



In most of the specimens of the small series before me the head 

 above is a little darker than the prothorax and in two, from the same 

 locality, is black above. 



This species is probably mixed with scatellaris or those with the 

 head black above with consanguinea. But scatellaris has a wider 

 prothorax with the lateral tubercles more prominent, the lateral 

 margin above the tubercles narrowing slightly to the apical angles 

 which latter are indistinct and slightly rounded; the antennal joints 

 are a little heavier and the size is generally larger. From consan- 

 guinea it differs in having the lateral tubercle of prothorax distinct,
