Abdomen beneath obsoletely granulose, finely, rather densely punc- 

 tate, the punctures connected transversely by sinuate lines, which are 

 coarser on the basal segments, sparsely clothed with short, recumbent, 

 inconspicuous hairs, and with a small spot of long, dense, recumbent 

 hairs at the sides of the anterior margin of the segments; first and 

 second segments convex at middle, and the suture between the two 

 segments plainly visible at the sides; last segment broadly rounded 

 at apex ; vertical portions of the segments not conspicuously pubes- 

 cent ; pygidium sparsely, coarsely punctate, with a strongly elevated 

 carina, which is not distinctly projecting. Presternum densely gran- 

 ulose, sparsely, coarsely punctate, feebly rugose, and sparsely clothed 

 with long, semierect, white hairs; prosternal lobe broad, rather 

 strongly declivous, and broadly transversely truncate in front; pro- 

 sternal process board, the sides feebly expanded behind the coxal 

 cavities, then strongly narrowed to the apex, which is acute. Tibiae 

 slender and unarmed at apex. Posterior tarsi much shorter than 

 tibiae, and the first joint about as long as the following two joints 

 united. Tarsal claws similar on all feet, cleft near the middle, the 

 inner tooth slightly shorter than outer one, and feebly turned inward. 



Length, 9.5 mm. ; width, 2.5 mm. 



Male. — Unknown. 



Redescribed from the lectotype No. 3483 in the Philadelphia Acad- 

 emy of Natural Sciences. 



Type locality. — "Lower California (Coral de Piedra, Sierra E] 

 Taste, and Pescadero.)" 



Host. — Unknown. 



According to the localities given in the original description, Horn 

 had at least three specimens before him when he described this 

 species, all of which were from the cape region of Lower California. 

 The writer has only seen one example of this species, and that is the 

 specimen labeled " lectotype 3483 " in the Horn collection, but that 

 specimen is simply labeled with a round orange disk, and without 

 any locality label. 



This species is very closely allied to pulchellus Bland in structural 

 characters, and in case the genus Engyaulus is separated from 

 Agrilus, inlidbilis should be placed in the former genus. It can, 

 however, be easily separated from pulchellus by having the elytra of 

 a uniformly bluish-green color, and without the pubescent vittae.
