side, involving largely the lateral margin. Surface punctured similarly to 

 quadrimaadatus. Femora black, tibiae red, abdomen red. Length 3 mm. 



Nogales, Arizona (F. W. Nunnenmacher.) 



A small species with thorax less transverse than the other species. 



Collops similis, new species. 



Head bluish-black, inter-antennal space and clypeus red. Antennal 

 joints red ; first joint stout, the other serrate. Thorax red at middle with 

 two, rather indistinct, darker lines. Elytra red, with basal and oval sub- 

 apical spotblue; surface more coarsely punctate than in quadrimamlaius 

 Fab. Front and middle femora red ; hind femora, tibias and tarsi black. 

 Abdomen red. Length 3.50 mm. 



S. W. Utah, collected by J. Chr. Weidt, of whom I. bought a few 

 specimens some years ago. This type is in the Museum collection. This 

 species has more coarsely punctate elytra than any other of the known 

 maculate species. 

 Collops punctulatus, var texaiius. 



Like piDictulatus Lee, except that the thorax is bright red. 

 Length 2 mm. 



Brownsville, Texas. 



A few specimens have tlie blueelytral vittse narrowly divided, forming 

 two large spots on each elytron ; in one specimen the spots are confluent 

 as in \\\)\Q,dX punctulatus. 

 Collops punctulatus, var. utahensis, new var. 



Differs ï:om punctulatus in having the elytral vittae broadly divided. 

 The basal spot is small and more or less transverse. The apical spot oval. 

 Length 2-2.25 ^"'^^• 



Buckskin, Utah. (Doll Sz Engelhardt.) 



Apparently a constant, local form oî punctulatus. 

 Collops sublinibatus, new species. 



Closely allied to C. georgianus Fall, from which it differs in having 

 the head polished, the disk of prothora^x shining, and scarcely punctate. 

 Length 3.5-4 mm. 



Clayton, Georgia. 



Through the kindness of my friend, Mr. William T. Davis, I have 

 seen a number of specimens which agree very closely with Fall's descrip- 

 tion 0Ï georgianus, except as above stated. From limbellus, it differs in 

 having the outer antennal joints not serrate, and the second joint is much 

 wider than long.
