5. LITHOCHARODES RAMBOUSEKI, new species 



Lithocharodcs ramhouseki Bieeig, MS. 



Description. — Rufous, marked with piceous as follows: A V-shaped 

 area from the posterior part of the vertex to each eye, vaguely on the 

 front of pronotum, the disk of the elytra, and each abdominal tergite. 

 Head two-ninths longer than wide, somewhat expanded behind, the 

 base feebly rounded ; antennal grooves feeble, arcuate, the epistoma 

 short ; ocular grooves absent ; with moderately large but not distinctly 

 umbilicate punctures except on midline; without distinct ground 

 sculpture on disk. Pronotum one-half longer than wide, widest in 

 front, narrowed to posterior two-fifths, base broadly rounded; with 

 smooth midline marked by rows of large punctures only a little closer 

 together than those over the rest of the surface. Elytra with surface 

 flat but finely coriaceous, with rather indistinct punctures not very 

 sparse. Abdomen with fine submuricate punctures; without ground 

 scultpure. Length, 5I/2 mm. 



Trjpe locality. — Cuba, Rio Almendares, province of Habana. 



Types. — HoJotype and one paratype, U.S.N.M. No. 52475, collected 

 by Sr. Bierig and sent as cotypes (No. 52736), though apparently 

 never published. Also one paratype in the Museum of Comparative 

 Zoology. 



Records. — The following are the records known to me: 



Cuba: Rio Almendares (Bierig, in U.S.N.M.), Asplro (Bierig, in U.S.N.M.), 

 Soledad (Darlington, in M.C.Z.). 



Specimens examined. — I have seen two examples sent several years 

 ago by Sr. Bierig and one from the Museum of Comparative 

 Zoology. 



Remarks. — This species is very distinct by its markings, but I am 

 not able to state the variability of these characters There must be 

 additional specimens in the collection of Sr. Bierig. 



I have no record of its habits.

Description. — Black to dark piceocastaneous, apex of abdomen 

 paler. Head nearly one-half longer than wide, scarcely at all 

 expanded behind the eyes, which are unusually large and separated 

 from base by two and one-half times their length; base straight 

 with angles moderately rounded; antennal grooves forming a 

 pareiithesis but obscured by strigulae; without ocular grooves; punc- 

 tures moderate and distinctly umbilicate, often slightly elongated 

 and genarally separated by about their diameter; without ground 

 sculpture on the disk; punctures near clypcus anastomosing and 

 obscured by strigulae and irregular ground sculpture. Pronotum
