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

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

 which is a rosaceous angjulated tranverse line. Leno-tli 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 attacking 

 the vine in Massachusetts, are Anomala varia7is Fabr., Pelid- 

 nota punctata Fabr., and several sphinges and moths. 



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

 me. 



Thanasimus f 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 tlie 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 longast ; labial palpi 3-jointed, first 

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

 securiform. Mandibles dentated at apex. Eyes notched. 

 Thorax obcordate or contracted behind. Description ; black, 

 'hairy, punctured ; mouth reddish beneath ; each elytron with 

 two 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.
