of cuneus occasionally almost covered by one or two 

 brown patches, also the tip and middle with brown streaks ; 

 the membrane pale, marked with a smoky bord, band and 

 base, the veins coarse, and yellow excepting the base. 

 Venter with two submarginal curved, very slender, in- 

 terrupted stripes of red. The dark color is sometimes 

 concentrated against the tip of the corium and the base 

 of the pronotum. 



Length to tip of abdomen, c5 , 4^^ ; ? , 4^-5 mm. 

 Width of pronotum, 2-2^4^ mm. 



This beautiful little species was found at San Jose del 

 Cabo by Dr. Gustav Eisen. Fragments of specimens 

 from Texas and Maryland have been for a long time in 

 my collection, but not in condition for identification. It 

 mimics in markings of thorax, and somewhat in figure, 

 certain varieties of Phytocorida^ related to P. colon Say. 



Neoborus saxeus Dist. Specimens in this collection 

 are marked "Cal. 9." A specimen more closely resem- 

 bling the variety described bv Mr. Distant was taken by 

 Mr. John Xanthus near Cape St. Lucas. This insect 

 presents all the varieties of color and marking possible to 

 its plan of development. It is met with entirely of a yel- 

 lowish-white, then nearly all black, others are greenish- 

 yellow with a black face and mostly black pronotum and 

 clavus, and with a large black spot near the apex of each 

 corium : these markings are sometimes replaced by brown, 

 purplish, or rosy red. Another variety has the face 

 marked with crimson, four stripes of the same color on 

 the pronotum, and the clavus and large spots of the cori- 

 um also crimson. 



It is sometimes very common in Maryland and the Dis- 

 trict of Columbia on the linden tree. It occurs as far 

 north as the central part of Maine.
