OF WASHINGTON. 139 



nearly as long as broad, feebly narrowing to base, apical angles dis 

 tinct, basal angles rectangular, base feebly lobed, side margins irregu 

 larly crenate, disk with four costae as in quadriguttatus, surface granu 

 late. Elytra slightly wider than the thorax at base, with the usual 

 four costse, which are very prominent and slightly crenate at their 

 summit ; intervals with two rows of well separated round perforate 

 punctures, separated by a broad, nearly smooth, longitudinal median 

 line ; color rufotestaceous, with darker markings as follows : One at 

 scutellum, one slightly below middle at suture, one on each side near 

 side margin, between the scutellar and sutural spot and apex more or 

 less piceous. Metasternum and abdomen obsoletely punctate and sparsely 

 pubescent. 



Length, 2.75-3 mm. 



Biscayne Bay and Key West, Fla. ; Cayamas, Cuba. For 

 the Biscayne Bay specimens I am indebted to Mrs. A. T. 

 Slosson ; the Key West and Cayamas specimens were collected 

 by Mr. E. A. Schwarz. 



Type. No. 10445, U. S. National Museum. 



The apical dark elytral space is variable in extent and is con 

 nected in some specimens with the marginal spots. The elytral 

 spots in some specimens are darker than in others. The color 

 ation, as well as the sculpture, distinguishes this species readily 

 from any of our species. 



Bitoma prosopis, n. sp. 



Elongate, piceous, opaque, sparsely pubescent; elytra with four not 

 clearly defined reddish spots, two occupying basal third, leaving suture 

 and sides narrowly piceous and two near apex. Head nearly smooth, 

 opaque, sparsely pubescent; antennal club two-jointed; clypeus cover 

 ing the mouth parts. Thorax slightly broader than long, apex and base 

 equal, feebly arcuate at sides, side margin finely crenulate, the inner 

 of the two lateral costae nearly obsolete, disk finely granulate and 

 sparsely pubescent. Elytra very little wider than the thorax at base, 

 with four elevated discal costse, which on their summit are slightly 

 crenulate and clubbed with short white hairs ; intervals with rows of 

 large coarse punctures, more or less transversely confluent, giving them 

 a rugulose appearance. Body beneath ferruginous, opaque; metas- 

 ternum and abdomen feebly punctate and sparsely pubescent. 



Length, 2 mm. 



Two specimens, one from New Braunfels, Tex., in Coll. 

 Dietz, the other from San Diego, Tex., in the Hubbard and 

 Schwarz collection, U. S. Nat. Museum; the latter was col 

 lected May 23 by Mr. E. A. Schwarz, whose manuscript name 

 I have used.
