American Caraboidea 259 



Apical pale areas joining the anterior in a broad and constant isthmus, 

 always isolating the submarginal small black spot 15 



15 — Body narrower, shining, pale in color, the head slightly infuscate; 

 prothorax testaceous, the elytra flavate, with a large common oval 

 sutural spot of black, the centre of which is well behind the middle, 

 extended along the suture to the scutellum by a narrow black vitta, 

 the submarginal spot of black slightly behind the middle, the apex 

 black, more widely so externally than suturally; under surface and 

 legs pale, the met-episterna and abdomen piceous-black; head five- 

 sixths as wide as the prothorax, with large and prominent eyes, the 

 surface smooth, but becoming longitudinally and feebly rugulose 

 laterally; antennae slender, testaceous, more than half as long as the 

 body; prothorax twice as wide as long to a trifle more, the sides 

 broadly rounded, moderately reflexed, broadly so at base, the angles 

 sharply defined; transverse rugulosity fine, not dense, the median 

 stria fine but rather deep; elytra fully a third longer than wide, 

 very feebly subdilated posteriorly, four-fifths wider than the pro- 

 thorax, the striae somewhat coarse and impressed, irregularly sub- 

 punctate, with the intervals slightly convex. Length 3.4-4.0 mm.; 

 width 1. 35-1. 6 mm. Southern California to Texas and l^tah 

 (southwestern, — Weidt) guttula Lee. 



Body broader, shining, the head deep black, the labrum pale flavate; 

 pronotum fusco-testaceous, gradually clearer laterally; elytra as in 

 guttula, except that the sutural spot is relatively not so large and the 

 apical fascia piceous and narrower; under surface and legs pale, 

 the met-episterna and abdomen piceous-black, the metasternum 

 blackish laterally; head nearly five-sixths as wide as the prothorax, 

 with large and prominent eyes, the surface finely rugulose through- 

 out, except at the middle of the vertex; antennae very slender, 

 more than half as long as the body, fuscous, the three basal joints 

 testaceous; prothorax very short, slightly more than twice as wide 

 as long, the arcuate sides more convergent at apex than in the 

 preceding, becoming very feebly sinuate at the sharp basal angles; 

 rugulosity rather fine but close-set and distinct; margins rather 

 more widely reflexed than in guttula; elytra much broader, scarcely 

 a fifth longer than wide, gradually dilated posteriorly, very nearly 

 twice as wide as the prothorax; striae finer and more feebly im- 

 pressed, the intervals not quite flat. Length 4.2 mm.; width 2.15 

 mm. California (Lake Co.), — Fuchs pacifica n. sp. 



The species described above under the name serpentina, is allied 

 closely to the Mexican calliope Bates, and was so identified by 

 Schaefifer, but it appears to be narrower and more elongate than 

 that species, the head piceo-rufous and perfectly smooth, and not 

 black and very obsoletely punctulate and striate as it is in calliope, 

 and the sides of the prothorax would appear to be somewhat more 

 widely explanate; the size of calliope is about 0.5 mm. greater. 

 An examination of the figure of calliope, given on the plate, would
