yellow, with a rosaceous fascia on the base of the hemelytra, 

 another on the middle, and a fuscous one at tip, just before 

 which is a rosaceous angulated tranverse line. Length one 

 tenth of an inch or one line. Thousands of these live on a 

 single leaf, and by their punctures exhaust the sap, and cause 

 the leaf to turn yellow or brown. The other insects attackino- 

 the vine in Massachusetts, are Anomala varimis Fabr., Pelid- 

 notajnmctata Fabr., and several sphinges and moths. 



This day (Oct. 25) I have found a small Thanasimus new to 

 me. 



Thanasimus? analis^ mi. Four anterior tarsi 5-jointed, 

 posterior tarsi (apparently) 4-jointed, the first joint being con- 

 cealed above by the base of the second joint. Antennae 

 clubbed, club 3-jointed, terminal joint ovate, obliquely subacu- 

 minate. Tarsal joints (except the claw joints and first of the 

 hind tarsus) sub-obcordate, hollowed above, and membrana- 

 ceous in the middle of the tip ; claw joints and first and second 

 of the hind tarsus obconic ; nails with a short robust tooth be- 

 neath the middle. Labrum transverse, emarginated, labium 

 bilobed, the lobes rounded ; maxillary palpi 3-jointed, joints 

 cylindrical, terminal one longest ; labial palpi 3-jointed, first 

 joint short, minute, second long, obconic, terminal joint dilated, 

 securiform. jVIandibles dentated at apex. Eyes notched. 

 Thorax obcordate or contracted behind. Description ; black, 

 hairy, punctured ; mouth reddish beneath ; each elytron with 

 tw^o arcuated white fasciae, convex forwards, one on the middle 

 and one near the tip; neuter pale sanguineous. Length .20 in. 



Oct. 26. Yesterday I gave the above characters, and to-day 

 I discovered Thanasimus formicarius Fabr., which exhibits all 

 of them except that the basal joint of the hind tarsi is much 

 more apparent.
