THE GKOUND BEETLES. 147 



southern third of the State. Very apt to be confused with ornata, 

 but easily distinguished by its punctured head and more deeply 

 striate elytra, 



253 (892). LEBIA ANALIS Dej., Spec. I, 1825, 265. 



Broadly oval. Head black ; antenna; piceous. the four basal joints 

 paler; thorax reddish-yellow, the margin paler; elytra black, each with 

 the narrow margin and usually a large irregular humeral spot and small 

 apical spot yellowish; under surface and legs pale yellow, abdomen darker. 

 Thorax broadly margined, finely and irregularly wrinkled. Length 4.5- 

 5.5 mm. 



Southern third of State; frequent. April 19-November 7. 

 Taken by sweeping low herbs. Readily known by the longitudinal 

 stride on head and the deep elytral strife. The pale markings of 

 eltyra vary greatly in extent and have given rise to a number of 

 synonyms. 



254 (893). LEBIA FUSCATA Dej.. Spec. I, 1825, 270. 



Broadly oval, subdepressed. Head and disk of thorax piceous; elytra 

 pale brownish-yellow, each with a narrow marginal line, a large scutellar 

 spot and a spot just behind middle, black; rarely the spots behind middle 

 merge to form a broad cross-band ; antennae, legs and under surface red- 

 dish-yellow. Thorax finely wrinkled, margin broad. Length 6.5 mm. 



Known from Indiana by a single specimen taken near Pine, 

 Lake County, by Wolcott. July 23. Resembles closely some of 

 the color varieties of analis, but distinguished by the larger size. 

 smooth head and dark disk of thorax. 



GROUP C. 



This group comprises the Indiana species of the subgenera 

 Dianchomena and Aphelogenia, which are separated only by the 

 head being more strongly constricted behind the eyes in the former.
