REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^E 83 



Group I. Type abdominalis. 



This group comprises the largest species of the genus ; they 

 are oblong-suboval in form, very convex, generally sparsely and 

 feebly punctured above, variably so beneath and are peculiar to 

 the southern coast regions of California, but few occurring at 

 any great distance inland. Whenever the locality of the indi- 

 vidual species is more accurately known it will be mentioned 

 after the respective descriptions, the exact locality of many 

 being unrecorded ; they are, as known to me at the present 

 time, some seventeen in number, as follows : 



Abdomen more or less closely and strongly punctured and rugulose, 

 at least at the middle of the basal segment ; prosternum strongly 

 punctured, the process margined throughout; body glabrous 2 



Abdomen very finely, sparsely punctured and smooth throughout, 

 even at the middle of the basal segment 9 



2 Elytral punctures strong and distinct though rather sparse 3 



Elytral punctures equally sparse, smaller and especially shallower and 

 much less evident 8 



3 Elytral surface even in convexity or having each about three feebly 



suberoded impressed lines 4. 



Elytral surface very rugose, each elytron with about six more close-set, 

 very irregular and subcostuliform lines of slight elevation 7 



4 Prothorax transverse, evidently more than one-half wider than 



long and apparently a little wider than the elytra in both sexes, 

 the sides more inflated and rounded than usual though similarly 

 rounding and converging anteriorly. Head and pronotum alu- 

 taceous, the elytra and under surface shining, the head strongly 

 and rather closely punctured, the surface feebly impressed at the 

 apical lobes, the anterior canthus of the eyes obtuse and equally 

 prominent with the posterior ; prothorax rather finely but strongly, 

 sparsely punctate medially, more closely and decidedly coarsely 

 laterally, the margin narrowly but strongly reflexed ; elytra barely 

 one-half longer than wide, parallel, obtuse behind, with the 

 margins rather abruptly and strongly reflexed, the surface feebly 

 rugose, strongly so at the apex, the punctures unusually coarse 

 for this section but sparse ; prosternum densely and the abdomen 

 sparsely, coarsely punctured and rugose. Length 15.0-17.0 mm. ; 

 width 7.3-8.0 mm. Near Monterey. [Fort Tejon, LeConte] . 



abdominalis Lee 



Prothorax about one-half wider than long, not inflated and not at all 

 wider than the elytra ; abdomen more finely, sparsely punctate 

 and rugulose only medially or toward the abdominal process at 

 base 5
