n8 MEMOIRS ON THE COLEOPTERA 



to the latter in ornamentation and sculpture throughout though 

 more narrowly oval, with a smaller head and with the elytral punc- 

 tures more confused as in the preceding species; head as in the 

 preceding species, finely, sparsely and very inconspicuously punc- 

 tured, the feeble clypeal sinus however broader, rather more than 

 half as wide as the clypeal base, the suture similarly straight and so 

 feeble as to be barely traceable; prothorax similar throughout; 

 scutellum red with black margins; elytra a fourth longer than wide, 

 barely wider than the prothorax, circularly rounded in posterior 

 two-fifths, the lateral swelling of the female rather large but feeble, 

 the short black explanate projection of the edge rather wider than 

 in deficiens but not conspicuous; punctures everywhere small, sparse, 

 impressed and confused; black sutural vitta forming a small quadrate 

 expansion on each at the middle and a larger rounded post-scutellar 

 expansion; subhumeral spot quadrate, separated by its own width 

 from the scutellar, the post-medial black spot moderate; pygidium 

 nearly similar in the sexes, very moderately convex, with fine punc- 

 tures, remote (9), or rather more numerous and distinct (cf), the 

 latter with the surface more impressed near the lower margins; 

 abdomen nearly as in all the preceding species; hind tarsi (cf ) much 

 longer, or ( 9 ) evidently shorter, than the tibiae, the basal joint in the 

 latter shorter and stouter than the second joint. Length (d 31 9 ) 

 ;2 1. 0-23. 7 mm.; width 11.1-12.2 mm. Mexico (Guerrero), Baron. 



*deceptor n. sp. 



6 Body oblong-oval, large in size, stout, convex, strongly shining; head 

 black and less shining throughout, large, three-fifths as wide as the 

 prothorax, the eyes better developed than in the preceding section 

 and the clypeal sculpture much coarser and denser, the punctures 

 confluent, slightly separated basally, the front sparsely punctate; 

 suture transverse, feeble; clypeus large, longer than the rest of the 

 head, not quite twice as wide as long, flat, the sides broadly arcuate, 

 becoming parallel basally, the angles obliterated, the sinus feeble, 

 more than half as wide as the base; prothorax three-fourths wider 

 than long, convex, the sides evenly arcuate, but slightly more con- 

 verging anteriorly, the apical angles acute and sharp, the basal 

 broadly rounded; lateral bead strong, rounding the angle and then 

 disappearing, traceable for a short distance by 'a feebly eroded line 

 of punctuation, flat and entire at apex, the coriaceous anterior part 

 with the usual medial angulation; color testaceous, with two approxi- 

 mate black vittae, which are prominent externally at the middle, 

 laterally prolonged at base not quite to the angles, the sublateral 

 medial spot of the preceding section wanting; punctures minute and 

 sparse, becoming more distinct, though sparse, at the sides; scutellum 

 ogival, well developed, pale, margined with black; elytra (9) a 

 fifth longer than wide, with a distinct lateral swelling behind the 

 middle and there a third wider than the prothorax, the marginal 

 projection below the swelling not caused by a deplanation, as in the 

 preceding section, but by a thickening of the edge; color and orna- 

 mentation exactly as in deceptor, the punctures more distinct and in 

 great part disposed in unimpressed series, more confused suturad
