American Caraboidea 289 



which is very feebly sinuate, with broadly rounded angles; basal foveae 

 distinct and shallowly prolonged; transverse impressions subobsolete; 

 surface with well spaced and transverse rugula but in great part not 

 evidently punctulate, feebly so peripherally; median line fine, broadly 

 impressed, not attaining the base; elytra notably long, three-fourths 

 longer than wide, feebly inflated behind, but little less than twice as wide 

 as the prothorax, the apices rectilinearly truncate, with flat beading, 

 the sides apically rapidly, arcuately converging; striae fine, shallow, 

 very minutely and closely but clearly punctulate; intervals distinctly 

 convex (cf ), or not quite flat (9 ), and with extremely minute, sparsely 

 scattered punctules; two dorsal punctures distinct, impressed, the an- 

 terior adjoining the third stria at two-fifths, the posterior not close to 

 the stria and at apical fifth to sixth. Length 10. 8-12. 5 mm.; width 

 3.7-4.5 mm. Arizona (Tugson), — Tucker. Seven specimens. 



The last ventral segment is broadly arcuato-truncate at tip in 

 both sexes, but there is only one setigerous puncture at each side 

 in the male, two in the female. The following seems to be another 

 allied species from the same locality : 



Lecalida nigritula n. sp. — Form and general characters nearly as in 

 the preceding, but darker in color, the anterior parts piceous, the pro- 

 notum broadly and diaphanously pale at the sides; elytra black, with 

 obscurely red reflexed margins; under surface piceous, the legs rufous; 

 surface polished, the micro-reticulation of the elytra very fine and feeble; 

 head a little larger, similarly elongate, nearly four-fifths as wide as the 

 prothorax, almost as in the preceding species throughout, except that 

 the eyes, though even larger, are notably less prominent; prothorax 

 larger, more transverse, between a fourth and third wider than long, 

 subsimilar in general features and with broadly, strongly reflexed margins, 

 but with the sides less arcuate, very much less converging though simi- 

 larly sinuate basally, the base much broader, wider than the apex; surface 

 nearly similar; elytra still longer, four-fifths longer than wide, barely 

 visibly swollen behind, only three-fourths wider than the prothorax, the 

 apices similar; striae not so fine, the close-set punctulation'^much more 

 distinct; intervals broadly convex, flat posteriorly, minutely, sparsely 

 punctulate, the impressed dorsal punctures almost similarly placed, the 

 posterior axial on the interval and between apical fifth and sixth. Length 

 12.0 mm.; width 4.3 mm. Arizona (Tugson), — Tucker. A single 

 female example. 



The fringe of the maxillary lobe is longer and denser in pimalis 

 than in nigritula, the apex of the lobe less abruptly and less ob- 

 liquely hooked and the last joint of the flattened outer lobe is a 

 little longer. The last antennal joint in pimalis much more notably 

 exceeds the tenth joint in length than in nigritula. In the latter 

 the elytra are more nearly parallel than in pimalis.
