Amhrysus calif ornicus Montd. 1897. 



Mont., Verh. Zool. Bot. Ges. Wien., XXVII, pp. 12-18. 



"Form oval, head yellowish ochre, as long as wide between the eyes 

 behind; interocular space with the lateral sides subparallel on the 

 posterior half, progressively narrowed in front on the anterior half. Its 

 width behind is equal to three times the transverse diameter of the eye 

 on the same level. Surface of the head ver • finely punctured, the punc- 

 tuation a little less strong near the eyes. Vertex nearly smooth, finely 

 rugulose, with the traditional spot of the genus a little broadened; very 

 attenuated in front, "divided" at mid length, brownish, but very vaguely, 

 poorly defined. 



"Pronotum a little longer than the head on the median line. The 

 anterior angle almost right angles, a little acute, not acuminate. The 

 lateral margins feebly arcuated, divergent behind on their entire length; 

 posterior lateral angles broadly rounded. Transverse furrow very plain, 

 sunken, quite strong on the margin, narrowly interrupted on the median 

 line; the punctuation fine and dense on the whole surface, a little more 

 accentuated on the two anterior parts of the lateral margin. The 

 anterior margin, which appears finely bordered between the eyes, is 

 marked also behind the middle by fine transverse wrinkles that are 

 rather crowded. The margin yellowish ochreous, rather broad; the disc 

 and interior portion a little darkened, by the dots and small brownish 

 blotches appearing poorly defined, the two median longitudinal ones a 

 little more visible, arcuated, converging in front and behind, but not con- 

 fluent, allowing between them a pale median line, unspotted, narrowed in 

 front, and behind, broadened a little beyond the middle. In front reach- 

 ing the anterior narrow black border, and behind reaching the transverse 

 furrow; the portion behind the furrow verv pale yellowish, unspotted, 

 finely and densely punctured. 'Scraped off' on a narrow margin, the 

 length of the posterior border of the pronotum. 



"Scutellum yellowish brown, finely and densely punctured with the 

 wrinkles very visible, little regular, and a little reticulated in places, 

 especially toward the base. The principal wrinkle occupies the mid- 

 length of the posterior half of the scutellum and is cut across a little 

 before the summit by another transverse wrinkle. 



"Elytra very finely and densely punctulate, granulate, of a yellowish 

 brown, quite uniform, with the margin of embolium clearer yellowish. 

 Commissure of the clavus a little longer than the middle of the length of 

 the scutellum. Membrane brownish, a little darker th?n the elytra. 

 Connexivum yellowish brownish, a little darker on a narrow band cover- 

 ing the sutures; posterior angles of the segments almost right angles, 

 very feebly acuminate, and not prominent. 



"Labrum very small, transverse, subrounded in front. Rostrum brown- 

 ish, darker at extremitv. Under the body a large part uniformly bro^vn, 

 legs yellowish, the femora paler than the tibiae; length, 7.2 mm.; width, 

 4.5 mm." Taken in California, as the name would imply.

"Head and pronotum smooth; the latter with the sunken points scat- 

 tered on the sides. Rather strong transverse wrinkles covering the 

 slight depression at the middle of the anterior border of the pronotum. 

 yellowish 'a dessins' the brown points less marked on the head and pro- 

 notum; the transverse furrow on the pronotum well marked, the color 

 clearer on the smooth region behind the transverse furrow. The pro- 

 notum very much widened behind, having the lateral margins very con- 

 vergent for almost the^r entire length. Postero-la^pral angle quite 

 broadly subtruncate, a little rounded. Eyes also quite strongly con- 

 vergent for almost their entire length. The length of the head is much
