pale ring near the base, tarsi dark. Length 6 mm., width 2.8 mm. 



Type: Male, USNM 61822, taken at Brownsville, Texas, March 9, 

 1949, in a shipment of tomatoes from Mexico. 



Remarks: Only one specimen of this is at hand, and this without 

 any definite locality label. It is more robust than D. glabrata 

 (Fabricius) and with darker markings beneath, a submarginal instead 

 of marginal vitta, and no thoracic spotting. The aedeagus bears a 

 certain resemblance to that of D. glabrata, but is more acutely tipped 

 and when viewed from the side not curved as in D. glabrata. It does 

 not have the large, well developed anterior angles on the prothorax of 

 D. barberi Blake, nor is there a basal depression on the prothorax 

 typical of that group. I believe it falls into the glabrata group. 



Disonycha adiimbrata Clark 



Disonycha adumbrata Clark, Journ. Ent., vol. 2, p. 401, 1865. 



Type: In BM, from Pard, Brazil, collected by Bates. 



There is apparently only one specimen of this, the type, which I 

 have examined at the British Museum. In my notes on that specimen 

 I questioned whether it was a species of Disonycha. The eyes are very 

 large and rather deeply emarginate, the antennal joints not quite 

 typical, in that the second and third joints are short and the fourth 

 at least twice as long as the third. The anterior angles of the pro- 

 thorax are obliquely cut. There is a faint sulcus at the base of the 

 pronotum with limited ends. The single reddish brown elytral vitta 

 from the humerus fades out at the apical curve. I could not find any 

 spur on the hind tibia and the claws are not typical of Disonycha. 

 At that time I did not attempt to place it in any other genus and feel 

 that without further examination I should not do so now.

"Elongate and subdepressed, testaceous, the terminal joints of the 

 antennae fuscous; thorax impunctate; elytra not perceptibly punc- 

 tured ; a very narrow sutural and a sublateral stripe and a broader 

 longitudinal band at the disc, black. 



"Length 9 mm. 



"Head impunctate, the clypeus with an acutely raised central ridge; 

 eyes reniform, rather deeply emarginate; antennae extending to the 

 middle of the elytra, rather robust, fuscous, the lower four joints 

 testaceous, the fourth joint nearly twice as long as the third; thorax 

 about one-half broader than long, the sides nearly straight with a 

 narrow margin, the posterior angles strongly oblique, anterior angles
