the middle, the transverse dorsal impression feeble. 

 Elytra with striae of punctures becoming much finer to- 

 ward the apex, the ninth entire, intervals broader than 

 the punctures, smooth. Body beneath and legs black 

 and shining. Length, .20-. 24 inch; 5-6 mm. 



Similar in form to conjtuicta or solani, but easily known 

 from all our species by the black head and thorax, with 

 the basal orange spot on each elytron.

Lema ^mula n. sp. 



Form of scxfiinctata, yellow or slightly orange, each 

 elytron with three black spots and a short common su- 

 tural stripe near the base. Antennce pale. Head with 

 an acutel}^ impressed v-shaped impression. Thorax 

 smooth, constricted at middle, the dorsal transverse 

 groove feeble. Elytra with stride of coarse and deep, 

 rather distant punctures becoming finer toward apex, the 

 intervals smooth and convex at apex, the ninth stride not 

 extending more than one-third tow^ard base. Body be- 

 neath pale, the sides of metasternum and tarsi darker. 

 Length, .18-. 20 inch; 4-5 mm. 



This species resembles sexfiiuctata and varies in a sim- 

 ilar manner. 



Typical for' m. — Elytra with a black spot on umbone, a 

 small oval spot between the fourth and sixth strias in front 

 of middle, a larger spot in the triangle formed by the 

 third and sixth stria? near the apex, a narrow sutural 

 stripe at base. 



Variety. — Elytra immaculate . 



Variety. — A broad sutural piceous stripe expanding ab- 

 ruptly near the apex. In all the specimens seen the an- 

 tenno? and legs are pale, in sexfiuictata piceous or black.
