Werner — Ischyropalpus 
193 
defined have the head and pronotum deeply sculptured, with the disc 
somewhat flattened and the base of the head and sides of the pronotum 
anterior to the constriction ending in a sharp margin that is lentic- 
ular in profile. 
Uniting Lappus with Ischyropalpus necessitates a rather large 
number of recombinations. To this number are added some new 
generic assignments and synonymy that have resulted from an examina- 
tion of the types. Bonadona has recently treated most of the species 
assignable to Ischyropalpus as previously defined (1961), and has 
made the changes necessary for these species. The new combinations, 
new synonymies, and the previous generic assignments of the species 
involved are given below, followed by a list of the species known to 
me, incorporating these changes. 
The following are new combinations: i. Species described in 
Anthicus: amplithorax (Pic), antic ef as ciatus (Pic), asphaltinus 
(Champion) (= Anthicus distinctus Pic, Lappus thicaniformis 
Werner, both new synonymy), aterrimus (Champion), baeri (Pic), 
dilatipes (Champion), externenotatus (Pic), impressus (LaFerte), 
laticeps (LaFerte), nigrofemoratus (Fairmaire and Germain), paral- 
lels (Fairmaire and Germain), subtilissimus (Pic) (substitute name 
for Lappus subtilis Casey, a junior secondary homonym in Anthicus) . 
2. Species described in Anthicus but transferred to Lappus by Casey, 
1895: bactrianus (Champion) (listed by Casey as backianus , a 
typographical error), nitidulus (LeConte) (= Lappus alacer Casey, 
asperulus Casey, canonicus Casey, cursor Casey, nubilatus Casey, 
vigilans Casey, all new synonymy), obscurus (LaFerte), occiden- 
talis (Champion), punctipennis (Champion), sturmi (LaFerte) 
(substitute name for elegans LaFerte, a junior primary homonym in 
Anthicus ) , tumidicollis (Champion). 3. Species described in Anthicus 
but transferred to Anthicus (Lappus) by Krekich, 1914: nitidus 
(Boheman) ( — Anthicus atomarius Boheman). 4. Species described 
in Anthicus (Ischyropalpus) : batesi (Pic), hemicyclius (Heberdey). 
5. Species described in Anthicus (Lappus) : dormei (Pic), goyasensis 
(Pic), postobscurus (Pic), proprius (Pic), sipolisi (Pic), vagema- 
culatus (Heberdey). 6. Species described in Lappus: lividus (Casey) 
(— Lappus bipartitus Casey, ornatellus Casey, solivagans Casey, 
vividus Casey, all new synonymy), pinalicus (Casey), turgidicollis 
(Casey) ( — Lappus animatus Casey, new synonymy). 
Anthicus trigonocephalus LaFerte 1848, described in the subgenus 
Ischyropalpus , is not included here. This species was described from 
India on the basis of a specimen lacking maxillary palpi. LaFerte 
placed it in a group separate from the South American species on the
