PSYCHE. 



[November 1S93. 



Cerceris austrina. ? .— Clypeus sub- 

 convex, not produced, its fore margins 

 rounded or subtruncate, strongly punctured, 

 its lateral lobes small and indistinct; front, 

 vertex and cheeks with coarse punctures, 

 those on the cheeks strongest; inner eye- 

 margins slightly converging towards the 

 clypeus; ocelli placed in a low triangle; 

 antennae tolerably long, thickened but little 

 to the apex, first joint of the flagellum about 

 one-quarter longer than the second, joints 

 2-4 about equal in length; thorax very 

 coarsely punctured, the punctures on the 

 mesopleurae irregular; sides of prothorax 

 somewhat excavated or depressed; mesopleu- 

 rae armed with two strong teeth beneath : 

 enclosure on metanotum triangular, parted 

 by a strong furrow which runs the entire 

 length of the metathorax, and with a number 

 of both oblique and transverse ridges; tibiae 

 and tarsi strongly spinose, the hind tibiae very 

 distinctly serrated on outer edge; the spines 

 on fore tarsi forming the comb rather short 

 and widely separated ; dorsally the abdomen 

 is less strongly punctured than the thorax, 

 segments 1-5 renexed at apex; ventrally the 

 base and apex of segments 2-5 are im- 

 punctate; pygidial area almost exactly ovale, 

 having the appearance of being scaly; black: 

 clypeus, sides of face, scape beneath, basal 

 half of mandibles, four anterior tibiae and 

 tarsi in part a transverse mark on pronotum, 

 separated in the middle, and scutellum 

 yellow; greater part of antennae, pronotum, 

 tegulae, legs, postscutellum, first abdominal 

 segment above, second and third segments, 

 except basal portions, rufous, apical portion 



A correction. — In Psyche 1893 (v. 6, p. 

 379) I described larvae received from Mr. J. 

 B. Lembert as Arctia blakei Grote. Since 

 then Mr. Lembert has sent a second specimen, 

 like the one from which the eggs were ob- 

 tained except that the veins of fore wings 

 are narrowly lined with flesh color. This 

 leads me to believe that the larvae described 

 were really those of A. ornata Pack, and the 

 varietal name proposed by me will not stand. 



of second dorsal segment, yellow; face and 

 clypeus clothed with pale silvery pubescence ; 

 head, thorax, and abdomen ventrally, with 

 pale fuscous hair: wings fuscous, nervures 

 testaceous. Length 11^ mm. 



c? • — Middle lobe of clypeus somewhat 

 pyriform, its anterior margin seemingly 

 tridentate, in consequence of its middle por- 

 tion being angularly produced; head coarsely 

 punctured, the punctures on front, vertex 

 and cheeks deepest; antennae longer than 

 in the $, second joint of flagellum a little 

 longer than either the third or fourth ; 

 mesopleurae not dentate; wings subfuscous 

 darker towards apex ; pygidial area coarsely 

 punctured; eighth ventral plate bifurcate; 

 colored like the female, except that the face 

 and clypeus is entirely yellow, and dorsal 

 abdominal segments 2-5 have generally a 

 narrow, yellow fascia at apex, the first and 

 second segments are both above and beneath 

 generally rufous; in some specimens the 

 second segment has no trace of rufous, while 

 in others the first three segments are more or 

 less marked with that color, apical half of 

 antennae black. Length 10-12 mm. 



So. Florida (Chas. Robertson). 1 $ and 15 

 $ specimens. Allied to verticalis Smith, but 

 differs in the less coarse sculpture, the 

 roughly and many ridged enclosure on 

 metanotum (in verticalis it is smooth) and 

 the somewhat stouter antennae. It resembles 

 verticalis very much, but the want of the ruf- 

 ous color on vertex and metathorax will gener- 

 ally distinguish it- It is larger than rufopicta 

 more coarsely sculptured and the rlagellum 

 is not so much thickened on apical portion. 



The synonymy will be : — 

 Eyprepia (Callarctia) ornata Pack.
