  We report the detection of very high-energy gamma-ray emission from the
intermediate-frequency-peaked BL Lacertae object W Comae (z=0.102) by VERITAS.
The source was observed between January and April 2008. A strong outburst of
gamma-ray emission was measured in the middle of March, lasting for only four
days. The energy spectrum measured during the two highest flare nights is fit
by a power-law and is found to be very steep, with a differential photon
spectral index of Gamma = 3.81 +- 0.35_stat +- 0.34_syst. The integral photon
flux above 200GeV during those two nights corresponds to roughly 9% of the flux
from the Crab Nebula. Quasi-simultaneous Swift observations at X-ray energies
were triggered by the VERITAS observations. The spectral energy distribution of
the flare data can be described by synchrotron-self-Compton (SSC) or
external-Compton (EC) leptonic jet models, with the latter offering a more
natural set of parameters to fit the data.
