reaching nearly to the middle of elytra, second joint smaller than the third, which is 

 about one third longer than the second, joints five to ten of equal width, but gradually 

 decreasing in length, last joint oval, one third longer than tenth. Thorax as long as 

 broad, very finely and sparsely punctured, more densely in front, pale testaceous, 

 black iq front of apical constriction, sides strongly narrowed behind, base narrower 

 than apex, a slight antescutellar impression. Elytra wider than the thorax, humeri 

 prominent, sides parallel, apices separately rounded, surface with strire of closely 

 placed not very large punctures, intervals with very sparsely placed fine punctures 

 bearing erect hairs, pale testaceous, a fascia across the base, suture nearly to apex 

 and at sides a narrow line, arcuately widened behind the middle, black ; side margin 

 to the middle pale. Body beneath and legs pale. Length, 6 mm. 



San Felipe, Lower California. Two specimens from Mr. G. 

 Beyer in the Museum of the Brooklyn Institute. The fifth abdominal 

 segment is triangularly emarginate, the last dorsal nearly truncate, 

 extremely feebly sinuate at middle, broader and larger than the sixth 

 ventral, they are probably males. The second joint smaller than 

 either of the two following places this species near xanti of Dr. 

 Horn's table, from which and from all our other species the elytral 

 markings separate it. In sonie specimens in Mr. Beyer's collection 

 the black markings are more or less confluent and the elytra may be 

 then more properly described as black with two pale spots, one large 

 elongate, one starting below the humeri and a smaller one at apex. 



Cymatodera obliquefasciata, new species. 



Form of inornata but more robust, brown, with an oblique yellowish fascia at 

 middle, reaching to the seventh striae, the sixth interval from the humeri to the fascia 

 yellowish, in some specimens only faintly indicated near the humeri and the fascise. 

 Antennre a little longer than head and thorax, serrate from the fourth joints, first 

 joint stout, as long as the next two, second joint small half as long as the third, joints 

 four to ten 'broader, serrate, subequal, eleventh elongate, narrower, as long as the 

 two preceding joints. Head coarsely somewhat cribrately punctured. Thorax longer 

 than broad, convex, sparsely hairy, sides nearly straight with a very feeble tuber- 

 cle at middle, surface somewhat vermiculate, no antescutellar impression. Elytra 

 broader than the thorax, humeri prominent, widening to apical third, then arcuately 

 narrowing to apex, which are separately rounded ; disk moderately convex, with ten 

 rows of coarse closely placed punctures becoming gradually finer towards apex and 

 entirely obliterated in the apical region, intervals slightly broader than the strife, flat, 

 finely punctate. Pro-, meso- and meta-sternum brown, the latter at sides and abdomen 

 testaceous, abdomen finely punctate, femora and tibiae brown, tarsi testaceous. 

 Length, lo-il mm. 



Brownsville, Texas (Esperanza Ranch), from Acacia flexicaiilis. 



Three specimens in the Museum of the Brooklyn Institute. The 

 fifth ventral is very slightly sinuate at middle, the sixth narrower, 

 rounded, last dorsal semicircular. The specimens seem to be females.
